The Rohde&Schwarz HMO3000 series are 300-500MHz, 4GSa/s, 2 or 4 analog channels and 16 digital channels mixed-signal oscilloscopes. This series was previously branded Hameg.

The HMO3522 and HMO3524 are an earlier series from Hameg and are also supported by this driver.

All models support different extension modules which provide different connectivity options.

Most models come with a HO730 (USB, Ethernet) module, other modules like the HO720 (RS232, USB) and the HO740 (GPIB) are available optionally.

All models come with analog probes (specific probe might depend on the scope capabilities).

Digital probes (8 or 16 channels) are optional and can be purchased separately, see HO3508.

The latest available firmware version from the HMO3000 series is V 6.005 (dated 21 April 2017).

The HMO3000 series has been discontinued in the first-half of 2018.

All the devices use the SCPI protocol (for reference, see the "SCPI Programmers Manual").

The serial parameters are configurable on the device, the standard settings are: 115200 baud, 8n1, no handshake, no flow control.

All models support USB connection to the computer in both TMC and VPC mode, as well as Ethernet connection (raw TCP over a user-configurable port).
