how can I capture the screen data sheet from netwrork analyzer?

[w1aai]

I think that we are closing in on the screen capture quest.

We purchased a Agilent 82357A GPIB interface and can see the 8722A with it and the PC.

Now we need to download screen captures...

Does NI have a way to do this with our existing equipment??

The ability to do an actual screen capture is dependent on the instrument. If there is an instrument command to do it and if there is a command to transfer that screen capture over the bus, then all you have to do is read the data returned and save it. If the instrument does not have this, then you will have to issue commands to read trace data, cursors, etc., display those with your program, and then save your programs screen in a suitable format.

If you are using LabVIEW, then there is a driver for the 8722C and 8722D that might help. You can go to http://www.ni.com/devzone/idnet/ for all instrument driver downloads.

Which NI product and driver do you recommend for use with the 8722C NWA? TNX...

I don't quite understand what you are asking. You said you already have an Agilent GPIB controller. Are you looking for a recomendation for the programming environment to use? There is no simple answer to that question. I happen to prefer LabVIEW and as I said, there is an instrument driver (a software program written in LabVIEW) available for it so you don't necessarily have to learn the instrument's command syntax to start using it in remote control situation. Besides LabVIEW, NI sells LabWindows/CVI which is an ANSI C compiler. They also sell add-ons for VB and C++ that make programming in those easier.

We only require the CSV output from the GPIB bus that is hooked to the HP8722C and that will do it...

We do not need to reconstruct the image into jpeg or any other format...

And I do not know what level of LABVIEW is required for this...

The LabVIEW base version will provide everything you need for instrument connectivity/control. LabVIEW full gives you a lot of analysis functions and a great tool for programming user interfaces called the event structure. The pro version adds the abiity to create an exe.
