Agilent E4440A display line and screen capture problem.

[Vincent90]

Have you tried the command page 78 of manual i linked you first ?

MODSAVT ? which saves a trace in module memory.

BR,

You can try  the HCOPY command. The other possibility is to use the MMEM commands to save the screen capture locally, copy the file and delete the local copy after. See the attached command reference document.

After placing a VISA read after VISA out, still got a timeout error..

I try to do a screen capture using intuilink, it gives me screenshots while the program isn't running, but fails to give me screenshots while the program is running, I think it is more or less like the labVIEW situation, the GPIB is giving out commands and meanwhile recieving data, is it this that causes the timeout error?

No, you can't really run two separate GPIB programs at the same time.

Since you have not provided the exact command you are sending or your code, it's impossible to say what is wrong with your code.

Hello Dennis,

The attached is my program, I am quite new to labview, my aim is to control the analyzer to measure amplitude at different frequencies and then save the screenshots on my pc.

Without the save screen part, which is a bit different from what I did yesterday, it is working alright.

But after adding the save screen command, it stops working.

+. + Knight please save me.

The error happens at the first VISA read, it gives a time-out error.

I'm posting by phone. Can you attach an image? No promises since I don't even have the manual for the instrument.

Thx again man, you can just help me check the structure. I am not quite familiar with the structure so it may cause error.
