Question: Can RFXpress be run independently of the AWG online/offline software?
Answer: Yes, it can run without AWG software running. However RFXpress software can detect the presence of AWG offline/online software and execute the AWG software in background.
Note: Incase of AWG instrument (online) make sure AWG software is running. RFXpress version might have issues running, if AWG online software is not executing.
