Agilent PNA N5224A

I need about 60 secs.

balan12, 

where did you get the instrument drivers from? I have a N5227A PNA, and I could not find Labview drivers anywhere. Agilent technical support was of little help.

[balan12]

I don't have the driver. I am using VISA Read and Write and communicating via the LAN port.

The error, " Visa Read timing out" which I had is due to I am sending write command and expecting to read the response from the analyzer.

When I programmed the N5224A over LAN, I used COM which is actually more flexible. Some commands are not available in SCPI.

However, if you want to do SCPI over LAN, then read http://na.tm.agilent.com/pna/help/latest/Programming/COM_Reference/Objects/SCPIStringParser_Object.h...

Thanks. I'm still getting used to it. Where can I find a list of all the necessary commands required for communicating with the N533xA series using VISA?

[elf_esteem]

That was N522xA, not 533x.

I get a timeout error for any operation other than *IDN? . My timeout is set to 20 seconds. Help needed.

Hijacking someone else's thread is not a good thing.

Stick to your own post http://forums.ni.com/t5/Instrument-Control-GPIB-Serial/SCPI-Command-to-make-S-Param-measurement-Agil...

Make sure you are not trying to read something that is not there. Example writing *CLS\n" and then trying to read will give you "timeout error".

I am able to display an S parameter measurement on the PNA window using the following commands.

CALC1:PAR:DEF:EXT 'measurement1', S11

DISP:WIND1:STAT ON

DISP:WIND1:TRAC1:FEED 'measurement1'

CALC1:PAR:SEL 'measurement1'

CALC1:MARK:STAT ON

However, when I use the CALC:DATA:SNP:PORT:SAVE command to write SNP data to a file immediately after the above commands, it doesn't save to file. Any help/suggestions?

Thanks.
