SCPI tests without instrument

Post by Lazariev » October 7th, 2015, 2:16 am

I set up an AWG70k interface program on a local computer which has no AWG. I wanted to test waveform creation and it worked. The program simulates running, switching outputs on/off etc.
Now I want to test SCPI commands with it. However, LXI doesn't start telling that there is no instrument found (quite reasonable: it is just a PC).
So if there is a way to do tests of SCPI commands on a local PC without AWG?

a dangerous assumption. it does not. there is no code to provide simulated feedback without the output board.
support for offline remote programmatic interface is possible but not supported by default. IIRC the awg software installer detects that it is a PC and not the instrument and does not install the VXI-11 server portion of TekVISA. the awg software does have it's own internal raw socket server which you could use but it is raw sockets, effectively the lack of a protocol.
