Is your model not supported yet? Get in touch! We need people to help us test other models in this series, and getting a new model supported is generally quick & easy.

== Connection ==

All models communicate via an optically isolated serial connection, at 9600 bps, 8 bits, no parity, and 1 stop bit (9600/8n1). Connecting to the devices can be done either via USB ([[Device cables#Agilent_U1173A|U1173A cable]]) or Bluetooth ([[Device cables#Agilent_U1177A|U1177A interface]] or U1117A interface).

== Protocol ==
All models in this series use generally the same protocol, with only minor differences between models – and none within the same range.

The meters will respond to commands, which consist of a short ASCII string followed by either LF or CR+LF. The meter will either send no response at all, some ASCII text followed by CR+LF, or <code>*E</code> followed by CR+LF if the command given was invalid.

Some events (such as turning the rotary switch) will cause spontaneous transmissions of event notifiers. These consist of a <code>*</code> character, a single character and CR+LF.

=== *IDN? ===
Sending the command <code>*IDN?</code> causes the device to return a comma-separated four-field string, compatible with the identical GPIB command. The four fields are vendor name, model name, serial number and version:

Agilent Technologies,U1232A,MY52020136,V1.00
Agilent Technologies,U1272A,MY5''xxxxxxx'',V2.04
Keysight Technologies,U1242C,MY5''xxxxxxx'',V1.20
Keysight Technologies,U1282A,MY5''xxxxxxx'',V1.03

=== *RST ===
Sending the command <code>*RST</code> causes the device to reset. The response is an asterisk followed by the current dial position, for example <code>*1</code> indicates the first position.

=== SYST:BATT? ===
The command <code>SYST:BATT?</code> returns a value indicating the device's battery level. The value is in a different format depending on the model series:

The U123xx, U124xC, U127xx and U128xx models return a percentage value, like this:
36%

The U124xx models return a value like this:
+1.04200000E+02

=== SYST:BEEP ===
The command <code>SYST:BEEP TONE</code> make the multimeter emit a beep.

=== SYST:BLIT ===
The commands <code>SYST:BLIT 1</code> and <code>SYST:BLIT 0</code> turn the screen backlight on and off. There is no response. The backlight timer will still run and turn the backlight back off again if it is enabled.

=== FETC? ===
The <code>FETC?</code> command returns the current measured value, as a floating point ASCII string, as in the following examples:

+9.25000000E-03
+0.00000000E+00
-1.01140000E+00
-9.10200000E-01

The sign characters are always present, and the value is always in normalized scientific format. This applies even when in a mode that uses integer numbers, 11 would be transmitted as <code>+1.10000000E+01</code>. If no valid measurement is available, i.e. the display shows "OL" or "-OL", the transmitted value is either <code>+9.90000000E+37</code> and <code>-9.90000000E+37</code> respectively.

For models with dual display, the <code>FETC? @2</code> command returns the current value from the secondary display, in the same format.

=== CONF: ===
The <code>CONF:</code> commands can be used to change modes and ranges on the multimeter. It is not to be confused with the <code>CONF?</code> query described below.

For a given rotary switch position, only those CONF: commands work that switch to modes that can be reached by pressing the range or shift buttons.

==== U124xx/U125xx models ====

Same as above for the U123xx, except for different ranges.

=== CONF? ===
The <code>CONF?</code> command queries the device's current measurement configuration.

==== U123xx models ====
This can be either one, two or three comma-separated fields. The number of fields depends on the first field's value, but the second field always denotes the measurement mode's range and resolution, and the third field is the current type (AC or DC). For example, this indicates AC voltage in the 600mV range:
V,0,AC

==== U124xx and U125xx models ====
The output consists of a quoted string with the meter's mode, followed by a space, two values, separated by a comma, denoting the current range, and the value of one count. The mode may optionally include a colon followed by a code denoting a submode relevant to that major mode.
For example, AC voltage mode with 1000mV range on a 10000-count U1241B would be given as:
"VOLT:AC +1.000000E+00,+1.000000E-04"

=== LOG: ===

Different commands can be used to retrieve the content of the different log memories from the multimeter. Those commands allow to retrieve log entries one by one, specifying the index of the entry to retrieve each time. When the index is greater than the index of the last logged value, the multimeter will return an error (<code>*E</code>). The actual commands depends on the model.

The response is presented as a quoted string whose length depends on the model.

Note that each log entry is also emitted by the multimeter whenever a new value is captured to the log.

==== U123xx models ====

The valid commands to retrieve log entries are yet to be determined.

Log entries are 15 characters long. Here is an example of log entry:
"050000210000200"

Note that the position of the decimal point is not explicitly given, it must be discerned from the range.

Is your model not supported yet? Get in touch! We need people to help us test other models in this series, and getting a new model supported is generally quick & easy.

== Connection ==

All models communicate via an optically isolated serial connection, at 9600 bps, 8 bits, no parity, and 1 stop bit (9600/8n1). Connecting to the devices can be done either via USB ([[Device cables#Agilent_U1173A|U1173A cable]]) or Bluetooth ([[Device cables#Agilent_U1177A|U1177A interface]] or U1117A interface).

== Protocol ==
All models in this series use generally the same protocol, with only minor differences between models – and none within the same range.

The meters will respond to commands, which consist of a short ASCII string followed by either LF or CR+LF. The meter will either send no response at all, some ASCII text followed by CR+LF, or <code>*E</code> followed by CR+LF if the command given was invalid.

Some events (such as turning the rotary switch) will cause spontaneous transmissions of event notifiers. These consist of a <code>*</code> character, a single character and CR+LF.

=== *IDN? ===
Sending the command <code>*IDN?</code> causes the device to return a comma-separated four-field string, compatible with the identical GPIB command. The four fields are vendor name, model name, serial number and version:

Agilent Technologies,U1232A,MY52020136,V1.00
Agilent Technologies,U1272A,MY5''xxxxxxx'',V2.04
Keysight Technologies,U1242C,MY5''xxxxxxx'',V1.20
Keysight Technologies,U1282A,MY5''xxxxxxx'',V1.03

=== *RST ===
Sending the command <code>*RST</code> causes the device to reset. The response is an asterisk followed by the current dial position, for example <code>*1</code> indicates the first position.

=== SYST:BATT? ===
The command <code>SYST:BATT?</code> returns a value indicating the device's battery level. The value is in a different format depending on the model series:

The U123xx, U124xC, U127xx and U128xx models return a percentage value, like this:
36%

The U124xx models return a value like this:
+1.04200000E+02

=== SYST:BEEP ===
The command <code>SYST:BEEP TONE</code> make the multimeter emit a beep.

=== SYST:BLIT ===
The commands <code>SYST:BLIT 1</code> and <code>SYST:BLIT 0</code> turn the screen backlight on and off. There is no response. The backlight timer will still run and turn the backlight back off again if it is enabled.

=== FETC? ===
The <code>FETC?</code> command returns the current measured value, as a floating point ASCII string, as in the following examples:

+9.25000000E-03
+0.00000000E+00
-1.01140000E+00
-9.10200000E-01

The sign characters are always present, and the value is always in normalized scientific format. This applies even when in a mode that uses integer numbers, 11 would be transmitted as <code>+1.10000000E+01</code>. If no valid measurement is available, i.e. the display shows "OL" or "-OL", the transmitted value is either <code>+9.90000000E+37</code> and <code>-9.90000000E+37</code> respectively.

For models with dual display, the <code>FETC? @2</code> command returns the current value from the secondary display, in the same format.

=== CONF: ===
The <code>CONF:</code> commands can be used to change modes and ranges on the multimeter. It is not to be confused with the <code>CONF?</code> query described below.

For a given rotary switch position, only those CONF: commands work that switch to modes that can be reached by pressing the range or shift buttons.

|}

==== U124xx/U125xx models ====

Same as above for the U123xx, except for different ranges.

=== CONF? ===
The <code>CONF?</code> command queries the device's current measurement configuration.

==== U123xx models ====
This can be either one, two or three comma-separated fields. The number of fields depends on the first field's value, but the second field always denotes the measurement mode's range and resolution, and the third field is the current type (AC or DC). For example, this indicates AC voltage in the 600mV range:
V,0,AC

The output consists of a quoted string with the meter's mode, followed by a space, two values, separated by a comma, denoting the current range, and the value of one count. The mode may optionally include a colon followed by a code denoting a submode relevant to that major mode.
For example, AC voltage mode with 1000mV range on a 10000-count U1241B would be given as:
"VOLT:AC +1.000000E+00,+1.000000E-04"

=== LOG: ===

Different commands can be used to retrieve the content of the different log memories from the multimeter. Those commands allow to retrieve log entries one by one, specifying the index of the entry to retrieve each time. When the index is greater than the index of the last logged value, the multimeter will return an error (<code>*E</code>). The actual commands depends on the model.

The response is presented as a quoted string whose length depends on the model.

Note that each log entry is also emitted by the multimeter whenever a new value is captured to the log.

==== U123xx models ====

The valid commands to retrieve log entries are yet to be determined.

Log entries are 15 characters long. Here is an example of log entry:
"050000210000200"

Note that the position of the decimal point is not explicitly given, it must be discerned from the range.

Is your model not supported yet? Get in touch! We need people to help us test other models in this series, and getting a new model supported is generally quick & easy.

== Connection ==

All models communicate via an optically isolated serial connection, at 9600 bps, 8 bits, no parity, and 1 stop bit (9600/8n1). Connecting to the devices can be done either via USB ([[Device cables#Agilent_U1173A|U1173A cable]]) or Bluetooth ([[Device cables#Agilent_U1177A|U1177A interface]] or U1117A interface).

== Protocol ==
All models in this series use generally the same protocol, with only minor differences between models – and none within the same range.

The meters will respond to commands, which consist of a short ASCII string followed by either LF or CR+LF. The meter will either send no response at all, some ASCII text followed by CR+LF, or <code>*E</code> followed by CR+LF if the command given was invalid.

Some events (such as turning the rotary switch) will cause spontaneous transmissions of event notifiers. These consist of a <code>*</code> character, a single character and CR+LF.

=== *IDN? ===
Sending the command <code>*IDN?</code> causes the device to return a comma-separated four-field string, compatible with the identical GPIB command. The four fields are vendor name, model name, serial number and version:

Agilent Technologies,U1232A,MY52020136,V1.00
Agilent Technologies,U1272A,MY5''xxxxxxx'',V2.04
Keysight Technologies,U1242C,MY5''xxxxxxx'',V1.20
Keysight Technologies,U1282A,MY5''xxxxxxx'',V1.03

=== *RST ===
Sending the command <code>*RST</code> causes the device to reset. The response is an asterisk followed by the current dial position, for example <code>*1</code> indicates the first position.

=== SYST:BATT? ===
The command <code>SYST:BATT?</code> returns a value indicating the device's battery level. The value is in a different format depending on the model series:

The U123xx, U124xC, U127xx and U128xx models return a percentage value, like this:
36%

The U124xx models return a value like this:
+1.04200000E+02

=== SYST:BEEP ===
The command <code>SYST:BEEP TONE</code> make the multimeter emit a beep.

=== SYST:BLIT ===
The commands <code>SYST:BLIT 1</code> and <code>SYST:BLIT 0</code> turn the screen backlight on and off. There is no response. The backlight timer will still run and turn the backlight back off again if it is enabled.

=== FETC? ===
The <code>FETC?</code> command returns the current measured value, as a floating point ASCII string, as in the following examples:

+9.25000000E-03
+0.00000000E+00
-1.01140000E+00
-9.10200000E-01

The sign characters are always present, and the value is always in normalized scientific format. This applies even when in a mode that uses integer numbers, 11 would be transmitted as <code>+1.10000000E+01</code>. If no valid measurement is available, i.e. the display shows "OL" or "-OL", the transmitted value is either <code>+9.90000000E+37</code> and <code>-9.90000000E+37</code> respectively.

For models with dual display, the <code>FETC? @2</code> command returns the current value from the secondary display, in the same format.

=== CONF: ===
The <code>CONF:</code> commands can be used to change modes and ranges on the multimeter. It is not to be confused with the <code>CONF?</code> query described below.

For a given rotary switch position, only those CONF: commands work that switch to modes that can be reached by pressing the range or shift buttons.

==== U123xx models ====
This can be either one, two or three comma-separated fields. The number of fields depends on the first field's value, but the second field always denotes the measurement mode's range and resolution, and the third field is the current type (AC or DC). For example, this indicates AC voltage in the 600mV range:

=== LOG: ===

Different commands can be used to retrieve the content of the different log memories from the multimeter. Those commands allow to retrieve log entries one by one, specifying the index of the entry to retrieve each time. When the index is greater than the index of the last logged value, the multimeter will return an error (<code>*E</code>). The actual commands depends on the model.

The response is presented as a quoted string whose length depends on the model.

Note that each log entry is also emitted by the multimeter whenever a new value is captured to the log.

==== U123xx models ====

The valid commands to retrieve log entries are yet to be determined.

Log entries are 15 characters long. Here is an example of log entry:
"050000210000200"

Note that the position of the decimal point is not explicitly given, it must be discerned from the range.

Is your model not supported yet? Get in touch! We need people to help us test other models in this series, and getting a new model supported is generally quick & easy.

== Connection ==

All models communicate via an optically isolated serial connection, at 9600 bps, 8 bits, no parity, and 1 stop bit (9600/8n1). Connecting to the devices can be done either via USB ([[Device cables#Agilent_U1173A|U1173A cable]]) or Bluetooth ([[Device cables#Agilent_U1177A|U1177A interface]] or U1117A interface).

== Protocol ==
All models in this series use generally the same protocol, with only minor differences between models – and none within the same range.

The meters will respond to commands, which consist of a short ASCII string followed by either LF or CR+LF. The meter will either send no response at all, some ASCII text followed by CR+LF, or <code>*E</code> followed by CR+LF if the command given was invalid.

Some events (such as turning the rotary switch) will cause spontaneous transmissions of event notifiers. These consist of a <code>*</code> character, a single character and CR+LF.

=== *IDN? ===
Sending the command <code>*IDN?</code> causes the device to return a comma-separated four-field string, compatible with the identical GPIB command. The four fields are vendor name, model name, serial number and version:

Agilent Technologies,U1232A,MY52020136,V1.00
Agilent Technologies,U1272A,MY5''xxxxxxx'',V2.04
Keysight Technologies,U1282A,MY5''xxxxxxx'',V1.03

=== *RST ===
Sending the command <code>*RST</code> causes the device to reset. The response is an asterisk followed by the current dial position, for example <code>*1</code> indicates the first position.

=== SYST:BATT? ===
The command <code>SYST:BATT?</code> returns a value indicating the device's battery level. The value is in a different format depending on the model series:

The U123xx, U127xx and U128xx models return a percentage value, like this:
36%

The U124xx models return a value like this:
+1.04200000E+02

=== SYST:BEEP ===
The command <code>SYST:BEEP TONE</code> make the multimeter emit a beep.

=== SYST:BLIT ===
The commands <code>SYST:BLIT 1</code> and <code>SYST:BLIT 0</code> turn the screen backlight on and off. There is no response. The backlight timer will still run and turn the backlight back off again if it is enabled.

=== FETC? ===
The <code>FETC?</code> command returns the current measured value, as a floating point ASCII string, as in the following examples:

+9.25000000E-03
+0.00000000E+00
-1.01140000E+00
-9.10200000E-01

The sign characters are always present, and the value is always in normalized scientific format. This applies even when in a mode that uses integer numbers, 11 would be transmitted as <code>+1.10000000E+01</code>. If no valid measurement is available, i.e. the display shows "OL" or "-OL", the transmitted value is either <code>+9.90000000E+37</code> and <code>-9.90000000E+37</code> respectively.

For models with dual display, the <code>FETC? @2</code> command returns the current value from the secondary display, in the same format.

=== CONF: ===
The <code>CONF:</code> commands can be used to change modes and ranges on the multimeter. It is not to be confused with the <code>CONF?</code> query described below.

For a given rotary switch position, only those CONF: commands work that switch to modes that can be reached by pressing the range or shift buttons.

Same as above for the U123xx, except for different ranges.

=== CONF? ===
The <code>CONF?</code> command queries the device's current measurement configuration.

==== U123xx models ====
This can be either one, two or three comma-separated fields. The number of fields depends on the first field's value, but the second field always denotes the measurement mode's range and resolution, and the third field is the current type (AC or DC). For example, this indicates AC voltage in the 600mV range:

=== LOG: ===

Different commands can be used to retrieve the content of the different log memories from the multimeter. Those commands allow to retrieve log entries one by one, specifying the index of the entry to retrieve each time. When the index is greater than the index of the last logged value, the multimeter will return an error (<code>*E</code>). The actual commands depends on the model.

The response is presented as a quoted string whose length depends on the model.

Note that each log entry is also emitted by the multimeter whenever a new value is captured to the log.

==== U123xx models ====

The valid commands to retrieve log entries are yet to be determined.

Log entries are 15 characters long. Here is an example of log entry:
"050000210000200"

Note that the position of the decimal point is not explicitly given, it must be discerned from the range.

Is your model not supported yet? Get in touch! We need people to help us test other models in this series, and getting a new model supported is generally quick & easy.

== Connection ==

All models communicate via an optically isolated serial connection, at 9600 bps, 8 bits, no parity, and 1 stop bit (9600/8n1). Connecting to the devices can be done either via USB ([[Device cables#Agilent_U1173A|U1173A cable]]) or Bluetooth ([[Device cables#Agilent_U1177A|U1177A interface]]).

== Protocol ==
All models in this series use generally the same protocol, with only minor differences between models – and none within the same range.

The meters will respond to commands, which consist of a short ASCII string followed by either LF or CR+LF. The meter will either send no response at all, some ASCII text followed by CR+LF, or <code>*E</code> followed by CR+LF if the command given was invalid.

Some events (such as turning the rotary switch) will cause spontaneous transmissions of event notifiers. These consist of a <code>*</code> character, a single character and CR+LF.

=== *IDN? ===
Sending the command <code>*IDN?</code> causes the device to return a comma-separated four-field string, compatible with the identical GPIB command. The four fields are vendor name, model name, serial number and version:

Agilent Technologies,U1232A,MY52020136,V1.00
Agilent Technologies,U1272A,MY5''xxxxxxx'',V2.04
Keysight Technologies,U1282A,MY5''xxxxxxx'',V1.03

=== *RST ===
Sending the command <code>*RST</code> causes the device to reset. The response is an asterisk followed by the current dial position, for example <code>*1</code> indicates the first position.

=== SYST:BATT? ===
The command <code>SYST:BATT?</code> returns a value indicating the device's battery level. The value is in a different format depending on the model series:

The U123xx, U127xx and U128xx models return a percentage value, like this:
36%

The U124xx models return a value like this:
+1.04200000E+02

=== SYST:BEEP ===
The command <code>SYST:BEEP TONE</code> make the multimeter emit a beep.

=== SYST:BLIT ===
The commands <code>SYST:BLIT 1</code> and <code>SYST:BLIT 0</code> turn the screen backlight on and off. There is no response. The backlight timer will still run and turn the backlight back off again if it is enabled.

=== FETC? ===
The <code>FETC?</code> command returns the current measured value, as a floating point ASCII string, as in the following examples:

+9.25000000E-03
+0.00000000E+00
-1.01140000E+00
-9.10200000E-01

The sign characters are always present, and the value is always in normalized scientific format. This applies even when in a mode that uses integer numbers, 11 would be transmitted as <code>+1.10000000E+01</code>. If no valid measurement is available, i.e. the display shows "OL" or "-OL", the transmitted value is either <code>+9.90000000E+37</code> and <code>-9.90000000E+37</code> respectively.

For models with dual display, the <code>FETC? @2</code> command returns the current value from the secondary display, in the same format.

=== CONF: ===
The <code>CONF:</code> commands can be used to change modes and ranges on the multimeter. It is not to be confused with the <code>CONF?</code> query described below.

For a given rotary switch position, only those CONF: commands work that switch to modes that can be reached by pressing the range or shift buttons.

==== U124xx/U125xx models ====

Same as above for the U123xx, except for different ranges.

=== CONF? ===
The <code>CONF?</code> command queries the device's current measurement configuration.

==== U123xx models ====
This can be either one, two or three comma-separated fields. The number of fields depends on the first field's value, but the second field always denotes the measurement mode's range and resolution, and the third field is the current type (AC or DC). For example, this indicates AC voltage in the 600mV range:
V,0,AC

=== LOG: ===

Different commands can be used to retrieve the content of the different log memories from the multimeter. Those commands allow to retrieve log entries one by one, specifying the index of the entry to retrieve each time. When the index is greater than the index of the last logged value, the multimeter will return an error (<code>*E</code>). The actual commands depends on the model.

The response is presented as a quoted string whose length depends on the model.

Note that each log entry is also emitted by the multimeter whenever a new value is captured to the log.

==== U123xx models ====

The valid commands to retrieve log entries are yet to be determined.

Log entries are 15 characters long. Here is an example of log entry:
"050000210000200"

Note that the position of the decimal point is not explicitly given, it must be discerned from the range.

Is your model not supported yet? Get in touch! We need people to help us test other models in this series, and getting a new model supported is generally quick & easy.

== Connection ==

All models communicate via an optically isolated serial connection, at 9600 bps, 8 bits, no parity, and 1 stop bit (9600/8n1). Connecting to the devices can be done either via USB ([[Device cables#Agilent_U1173A|U1173A cable]]) or Bluetooth ([[Device cables#Agilent_U1177A|U1177A interface]]).

== Protocol ==
All models in this series use generally the same protocol, with only minor differences between models – and none within the same range.

The meters will respond to commands, which consist of a short ASCII string followed by either LF or CR+LF. The meter will either send no response at all, some ASCII text followed by CR+LF, or <code>*E</code> followed by CR+LF if the command given was invalid.

Some events (such as turning the rotary switch) will cause spontaneous transmissions of event notifiers. These consist of a <code>*</code> character, a single character and CR+LF.

=== *IDN? ===
Sending the command <code>*IDN?</code> causes the device to return a comma-separated four-field string, compatible with the identical GPIB command. The four fields are vendor name, model name, serial number and version:

Agilent Technologies,U1232A,MY52020136,V1.00
Agilent Technologies,U1272A,MY5''xxxxxxx'',V2.04
Keysight Technologies,U1282A,MY5''xxxxxxx'',V1.03

=== *RST ===
Sending the command <code>*RST</code> causes the device to reset. The response is an asterisk followed by the current dial position, for example <code>*1</code> indicates the first position.

=== SYST:BATT? ===
The command <code>SYST:BATT?</code> returns a value indicating the device's battery level. The value is in a different format depending on the model series:

The U123xx, U127xx and U128xx models return a percentage value, like this:
36%

The U124xx models return a value like this:
+1.04200000E+02

=== SYST:BEEP ===
The command <code>SYST:BEEP TONE</code> make the multimeter emit a beep.

=== SYST:BLIT ===
The commands <code>SYST:BLIT 1</code> and <code>SYST:BLIT 0</code> turn the screen backlight on and off. There is no response. The backlight timer will still run and turn the backlight back off again if it is enabled.

=== FETC? ===
The <code>FETC?</code> command returns the current measured value, as a floating point ASCII string, as in the following examples:

+9.25000000E-03
+0.00000000E+00
-1.01140000E+00
-9.10200000E-01

The sign characters are always present, and the value is always in normalized scientific format. This applies even when in a mode that uses integer numbers, 11 would be transmitted as <code>+1.10000000E+01</code>. If no valid measurement is available, i.e. the display shows "OL" or "-OL", the transmitted value is either <code>+9.90000000E+37</code> and <code>-9.90000000E+37</code> respectively.

For models with dual display, the <code>FETC? @2</code> command returns the current value from the secondary display, in the same format.

=== CONF: ===
The <code>CONF:</code> commands can be used to change modes and ranges on the multimeter. It is not to be confused with the <code>CONF?</code> query described below.

For a given rotary switch position, only those CONF: commands work that switch to modes that can be reached by pressing the range or shift buttons.

==== U124xx/U125xx models ====

Same as above for the U123xx, except for different ranges.

=== CONF? ===
The <code>CONF?</code> command queries the device's current measurement configuration.

==== U123xx models ====
This can be either one, two or three comma-separated fields. The number of fields depends on the first field's value, but the second field always denotes the measurement mode's range and resolution, and the third field is the current type (AC or DC). For example, this indicates AC voltage in the 600mV range:
V,0,AC

==== U124xx and U125xx models ====
The output consists of a quoted string with the meter's mode, followed by a space, two values, separated by a comma, denoting the current range, and the value of one count. The mode may optionally include a colon followed by a code denoting a submode relevant to that major mode.
For example, AC voltage mode with 1000mV range on a 10000-count U1241B would be given as:
"VOLT:AC +1.000000E+00,+1.000000E-04"

=== LOG: ===

Different commands can be used to retrieve the content of the different log memories from the multimeter. Those commands allow to retrieve log entries one by one, specifying the index of the entry to retrieve each time. When the index is greater than the index of the last logged value, the multimeter will return an error (<code>*E</code>). The actual commands depends on the model.

The response is presented as a quoted string whose length depends on the model.

Note that each log entry is also emitted by the multimeter whenever a new value is captured to the log.

==== U123xx models ====

The valid commands to retrieve log entries are yet to be determined.

Log entries are 15 characters long. Here is an example of log entry:
"050000210000200"

Note that the position of the decimal point is not explicitly given, it must be discerned from the range.

| Rotary switch position has changed. <code>*0</code> denotes the most counter-clockwise position (excluding the OFF position), then the value is increased by one for each step in the rotary switch's range. On the U127xx models the codes range from <code>*0</code> through <code>*10</code>.

|-
| <code>*B</code>
| Battery voltage dropped to "battery empty" level.

|-
| <code>*E</code>
| Invalid command.

|-
| <code>*I</code>
| Probes are connected to the wrong sockets for this mode, "Cerr" is shown on display (not supported on U123xx; it ''is'' supported on U127xx).

|-
| <code>*L</code>
| A button was pressed (not supported on U123xx, U127xx and U128xx). This notifier is only sent once after a command, even if the user presses several buttons.

sigrok is intended as a flexible, cross-platform, and '''hardware-independent''' software suite, i.e., it supports various devices from many different vendors.

Here is a list of currently supported devices (various stages of completeness) and devices we plan to support in the near future.

The lists are sorted by category ([[File:Nuvola OK.png|16px]] supported: [[:Category:Supported|{{PAGESINCATEGORY:Supported|pages}}]], [[File:Nuvola Orange.png|16px]] in progress: [[:Category:In progress|{{PAGESINCATEGORY:In progress|pages}}]], [[File:Nuvola Red.png|16px]] planned: [[:Category:Planned|{{PAGESINCATEGORY:Planned|pages}}]]), and alphabetically within those categories.

}}

The '''HP 6632B''' is a single channel 100W DC programmable power supply with GPIB and RS232 connectivity. It is part of the [[HP 663x]] series. The same device appears with HP, Agilent and now Keysight branding, following the history of subdivision of the company.

The device uses the same SCPI command set over both the RS232 and GPIB ports. The interface and communications settings to use must be selected from the front panel before remote use.

All connections are on the back panel, unless an optional set of front panel binding posts are fitted. The unit is designed to be rack mountable.
