Detailed Description

Implementation of the WG Command interface defined by Mair & Rohner OEG (M&R Systems, www.mrsys.at) for their waveform generators.

Tested with waveform generator WG-1220.

Todo:

Implement timeout waiting for the device

Implement the missing commands

Definition at line 31 of file wgcommand.h.
