Help! How can a transfer a screen shot to my computer with GPIB?

[JohanZhang]

I am using Labview 6.1 and through GPIB i can remote control Spectrum Analyzer(SA). I can use the command to save the screen shot on the SA to its local hard disk. But I wonder whether I can save the screen shot to my computer's hard disk. Thanks.

Your question is somewhat generic becuase you don't mention the make and model of the instrument. For a somewhat generic answer, read the manual to see if there is support for transferring a file or doing a print. For a more specific answer and a certain model of SA, you can see this. You can also search the forum yourself. Try using the model number as a search item. Whenever this question comes up, I also have to ask why do a length transfer from the instrument to the pc when the information ia already on the front panel of your LabVIEW VI? Presumably you are using LabVIEW to control and capture data from the instrument and it's simple to just print a LabVIEW graph or front panel.

The SA is E4437B from Agilent and FSU from R&S. I need the screen shot just because there is the manufacture logo on the screen, which our custom wants to verify our test data. I need help. Though I can manage it by mapping a computer's hard disk to SA, I want to know how to do it just by GPIB. Thanks.

I posted the incorrect link. This might help even though it is for a different model. You should be able to verify if the same commands exist in the manual for your instrument. Or you can use the same trick I suggested if you have Agilent's IntuiLink.

In FSU Instrument Driver there's VI called RSFSU Inititate Hardcopy to File.vi, which does exactly what you need. You can find it in pallete tree Action/Status->General Device Settings->Hardcopy.
For Agilent box I have no advice.

There is a free program from R&S called GPIBShot that can be used to capture screen shots from FSxx specans in BMP and WMF formats. You'll need to use command line approach with System Exec.vi residing under Connectivity menu in block diagram. This way you can even save pictures in colors.

Thanks all.

I have tried hardcopy but in vain. Can someone list the details of the command?

GPIB shot is kind of solution, but it is not easy for auto-test, I think.

If driver VI does not work, we shall fix it. Could you please send me more details how did you use it and what is the error message and code? Thanks.

"GPIB shot is kind of solution, but it is not easy for auto-test, I think."

Au contraire, it doesn't get easier than this (see attachment).

PS. You'll need to open the GPIBShot aplication and peruse through menus to set up default values on events, such as path on save event, image format, et.c. This VI assumes GPIBShot is installed in c:\program files\gpibshot\GPIBShot.exe  directory.

The VI is for R&S FSIG(SA). I can not find the "hardcopy" vi. But I have read the "programmable manual" and command line in the vi trying to get the information. But I found the "hardcopy" can save images to three ways: memory, clipboard, printer. which should I use? And how to use? Can you be kindly enough to send me the vi with command lines?
