Can't read markers from Agilent PNA

[hammer3]

OK, then where does all the trace, scale, and marker information come from that appears on the screen when I load the .sta file?

Your calling a measurement called MY_MEAS that is not define, that why you have an error.

Measurements including limit lines and markers are included in .sta file but under what name? Probably something like CH1_S12_1 in your case. You can try to send the following command using the VISA Write function: CALC1:DEF:CAT? and use VISA Read to get the returned string. The return string is the catalog of all defined measurements for channel 1 in this case (measurement name + parameters). Alternative is to define and name the measurement as I said in a previous post.

All I am going to say again, is READ the Help file.

The problem with many LabVIEW peoeple is that they don't bother reading the manual to understand how the equipment works and just blindly cobble together VIs together to get "something working".

hi. hammer

Is your problem solved or not ? If yes then please tell me how?

I am using PNA-X N 5242A for my measurement & facing same problem like you.

After normalising my path using PNA I save the PNA settings in .csa file. So when I recall that file &  try to read the markers it gives error.

Even I am not able to change the marker frequency.

Looking for Help

Hi R.V.

Since this thread is about a year and a half old, you may get better help if you posted a new topic and referenced this one. I would recommend the Instrument Control forum, as this issue may be more suited for a hardware forum: http://forums.ni.com/t5/Instrument-Control-GPIB-Serial/bd-p/140

Since these fellows were little help with lots of sarcasm, I eliminated the limit lines and checked limits with post processing.

Hi JasonAE

Thank you for the reply.

You are correct. I should post the query in GPIB board but I have post some queries in different boards (other than Labview) also but I did not get any reply for these queries.

Hi hammer 

thanks for the reply

My problem to configure marker & read them is solved. I got solution from "ben64" post. Now I am using same measurement name.

Now I am facing problem in generating the pulse from PNA. Have you tried it from Labview

Search for SENSE : SWEEP : PULSE commands in the following document (in Programming -> SCPI ->Commands->Sense->Sweep)
