PNA Guided Calibration: GPIB write error in for loop

[Benjamin38]

The I/O Trace is only going to monitor the writes and reads done from the machine/PC you are running it on.  There is no way you'll be able to run the utility without that.  There could be some other analyzer outside of NI that could accomplish this, but I'm not aware of anything.

I had a look at this forum...have you tried to execute the monitor utility on the device described below?  

One other thing you can try to see if LabView is mangling the command somehow, is to turn on PNA's SCPI monitor and observe what commands it is actually receiving. the SCPI monitor can be turned on using the Utility->System->Configure->SICL/GPIB/SCPI... menu. You can also turn on NI's IO monitor on your PC and compare what is being sent and what is being received to see if there are any discrepancies.

I would also suggest executing the commands in MAX. Try switching the order as well - i.e. step #2 first.

p.s. There are two methods to communicate in MAX - VISA and low level GPIB. You can try both.

If your VB script is saved on the PNA then your PNA is probably set in the GPIB System Controller mode. To run your LabVIEW program you should disable this mode: PNA system menu, click SICL/GPIB, in the GPIB box uncheck System Controller.

Hope this help.

Note that how your setup is connected is also important. To control from a remote PC the GPIB between the PC and PNA should be connected to the GPIB Talker/Listener port. If the power meter is not connected to the PC but from the PNA you should use USB/GPIB interface between the PNA and power meter. Refer to the user manual (search for External test set control) ther may be some more settings to adjust.
