GPIB Read Error HP4145B

[r.pennock]

Hello, 

I'm trying to set up my HP4145B semiconductor parameter analyzer (very old device) using labview 2012 and am encountering some issues!  I can successfully send commands to the instrument and it will take measurements, however I cannot get the SPA to output the data to my computer.  I am using the VIs that come with the instrument driver, downloaded at:

http://sine.ni.com/apps/utf8/niid_web_display.download_page?p_id_guid=E3B19B3E948F659CE034080020E748...

and I have isolated the issue to the GPIB Read function within the Data Ouptut VI.  Every time that I try to run the Data Output VI I receive error 6: HP4145 Receive Message.  Using NI-Spy I've figured out that it is a time-out issue, but I don't know how to solve it.  I've attached my NI-spy capture.  

There have been some posts about this a couple years back, but the solutions they came up with consisted of adding a delay between the Send Message and Receive Message VI's, which I have tried, but to no avail.  

Does anyone have any ideas on how to solve this?? Any advice would be very much appreciated!

Thanks, 

Rich

It might very well be an issue with timeout. The instrument will only answer when the entire measurement is completed. Depending on your setup, this can be a long time - much longer than the standard timeout setting of a few seconds. Check how long the measurement takes and set timeout accordingly

Good luck
