The '''Noname LHT00SU1''' is a USB-based, 8-channel logic analyzer with up to 24MHz sampling rate, with 1 additional analog channel (theoretically 2, but only one of them can be used at a time; 3MHz analog bandwidth).

It is a clone of the [[CWAV USBee AX-Pro]].

In sigrok, we use the open-source [[fx2lafw]] firmware for this logic analyzer.

'''Note''': [[fx2lafw]] currently doesn't support switching between the two possible analog channels, 1ACH will be used unconditionally.

See [[Noname LHT00SU1/Info]] for some more details (such as '''lsusb -v''' output) on the device.

== Hardware ==

There's a jumper on the PCB which write-protects the I²C EEPROM when set (it ships in that state) by keeping the WP pin at 3.3V.
