problem with Agilent 8510C network analyzer in frequency set command by GPIB

[yasmain62]

Hi I downloaded Plug and Play (project-style) driver for Agilent 8510C network analyzer. I run VI and want to set start and stop frequency, but it doesn’t execute correctly. It mean’s that the start and stop frequencies don not change! I attached the main VI. I would really appreciate any help. Thank you Yasamin Gharib

I do not see an attached VI.

Are you getting any errors?  Are you getting responses back from querries?  The first thing to check would be that you are actually talking to the instrument.  It could be something as simple as having the wrong GPIB address.

As a point of reference guys, you might want to read his other post about the 8510C.  http://forums.ni.com/t5/Instrument-Control-GPIB-Serial/problem-with-Agilent-8510C-network-analyzer-G...

If that problem isn't resolved, then I don't know why he is bothering posting again.

I could preset 8510c by this VI but I have problem in reconfiguration.

I could connect to 8510 correctly, because I can preset or check id query.

but my problem is in start/stop or center/span frequency setting in "stimulus sweep.vi" which I attached it.

thanks

compare the command being sent by driver to what the command should be per Programmer's Manual for 8510C
