Hi,
 
I'm trying to take burst power measurements using an Agilent MXA 9020.  the drivers so far have been great for taking most measurements but i have found it difficult for some specific measurements.  I noticed in the configure measurement type VI and configure measure VI it lists all types of measurements but in the read measurement VI it only has a few listed with the others, burst power included, in an "other measurements" option.  I can successfully take measurements of the listed ones but any of the "other measurements" the VI just hangs up and doesnt get anything back from the MXA.  if anyone has any suggestions or has dealt with this before it would make my day to find a solution!
 
thanks
 
Brent

Howdy Brent, I have not seen this before so it could either be a problem with the driver or a problem with the instrument.&nbsp; Can you post an <a href="http://digital.ni.com/public.nsf/allkb/8D890EC09B15C05A86256E6F007E3E86?OpenDocument" target="_blank">NI Spy Capture</a> of the communication between your computer and MXA?&nbsp; Also, what bus are you using to communicate with your instrument?&nbsp;

Hello Brent,&nbsp;I'm sorry if I do not have an answer right away, but would it be possible to attach the .SPY file to a post so we can see the complete file.&nbsp; Also, would it be possible to attach the high level VI you are using for this capture.&nbsp;Thanks and have a great day.&nbsp;
