Hello,
I have following problem:
Currently I'm writing a software which is communicating with a network analyzer and an Accretech UF200 Waferprober using VISA. Both are connected to my computer via an GPIB to USB adapter.
Scenario 1: Only Network Analyzer is connected
Everything works fine and I can send commands and receive answers from the network analyzer.
Scenario 2: Both Network Analyzer and Prober are connected
When I try to send a command (no matter which one) using RawIO.Write() I immediately get the error: Unable to start operation because setup is invalid (due to attributes being set to an inconsistent state)
I also tried sending commands with NI MAX but I get the same result there with the prober.
When I try sending a query to the Network Analyzer with NI MAX I just get a timeout error.
I have also appended a screenshot of the IO Trace where I request the prober ID. Unfortunately it's in German but the last line contains the mentioned error message.
I really don't know what causes this problem or how to fix it. Do I have to change any settings?
Did anybody else have encountered this problem or has an idea on how to solve this issue?
Best regards,
Jakob
