Dear all,

I am quite new to this web. I am trying to program PSA Series Spectrum Analyser using using LabView 8.0 (SCPI commands). The aim is to get a screen shot of the spectrum analyser measuement. What are the commands that will allow me to do so ? Are there are any Labview VI for the this spectrum analyiser which would allow me?

The option are either to receive a snap shoot of the measurment saved as a file or to directly display the sanp shoot on a LabView graph. I prefer to be able to get a snap shoot saved on a file within a specified directory.

Looking forward to hear anything related.

Best Regards,

BASHAR

I don't know of a Labview VI that will accomplish this. I do know there is a VI that functions as a pass-though that will allow you to send SCPI commands directly to PSA. You can use that VI and the following SCPI commands to create your screen shot file in the PSA flash memory and then transfer the file to your PC. You can then delete the file from your PSA if you chose. This can all be done via SCPI.

MMEM:STOR:SCR 'C:/MYSCREEN.GIF'
// This command creates a gif screen shot image
// named MYSCREEN.GIF the file on the PSA C: drive

MMEM:DATA? 'C:/MYSCREEN.GIF'
// This command will return the file in binblock format

MMEM:DEL 'C:/MYSCREEN.GIF'
// This command will delete the file from PSA

I don't have much experience with Labview, but I image there may be some file management VIs that would also allow you to move files from your PSA to your PC.

Best Regards,

Greeting,
I am still using the Labview 7.0 and unable to open the PSA Screen Capture via GPIB using LabView. vi that posted in this forum. Is that possible for you to convert it to labview 7.0.

Thanks.

Since you can only go back 1 version in LabView and I have 8.2 installed, I could only save a 8.0. You might take a look at the screenshots of the vi block diagrams in the original post's zip file.

I believe the vi that you are looking for is the "Write Binary File" vi as the first one and the "Close File" vi as the second one.
