MS2026 -anvna Wait for Acquisition Complete -ERROR

[frnz]

Hi Everyone,

I wrote a labview program (LV 7.1) with instrument MS2026A VNA (Anritsu) and it was working fine.

However the original equipmet stopped working last week and we have received a loaner (until our is fixed), same model, but does not work with my labview program.  I even try running this equipment with the sample program provided by NI:  "anvna Acquire Trace Example" and it gives me an error -please refer to attached pictures.

The error is in the "anvna Wait for Acquisition Complete.vi."  I think it has to do with timeout (256).  I have added delays all over but nothing helps.  I used to have this same problem on the first instrument but it disappear "mysteriously."

Could somebody point me to way to fix this issue?   Thanks very much,

Frank

New information:

I have tried the following samples VIs and all failed at the same vi as explained before (anvna Wait for Acquisition Complete.v) and all failed at the same place (please refer

to attached picture):

anvna Acquire Continuous Trace Example.vi

anvna Acquire Marker Data Example.vi

anvna Acquire Smith Plot Example.vi

anvna Acquire Trace Example.vi

The only VI that works is: 

anvna Transfer Current Waveform Example.vi

This VI does not call "anvna Wait for Acquisition Complete.vi"  - Any thoughts?

Thanks,

Frank

Dennis Knutson or Altenbach -Do you have any thouhts as to why all 4 examples VIs for this equipment's library stop at "anvna Wait for Acquisition Complete"

Thanks very much,

Frank

Hi Fvalenzu,

I have a few questions about your application. 

Is the replacement instrument the same revision of the instrument you sent to get repaired? 

Is the device at the same address? 

Are you able to successfully communicate with the instrument in max using GPIB commands?

You might want to verify the program is calling the instrument by the correct alias or address and you are calling the device correctly.  Also, I would check and see if there is a newer version of the IVI driver for your instrument. IVI drivers can be found at the link below.

Andy,

I contacted Anritsu's tech support and upgraded this model to latest firmware and my labview code appears to be working fine.  Therefore at this point it appears that everything is working fine.  Thanks for your reply.
