HOW TO GET OSCILLISCOPE "Screen Capture" ON THE FRONT-PANEL?????

[Vikram -Hardware Techy]

Hi All,
I have a lot of parameters displayed on the Tektronix Oscilliscope like the trigger level, the frequrncy,CH1 T/Div and probably many others along with the Waveform(obviuosly!).
I need to capture this exact oscilloscope screen on the Front Panel.

Kindly help me out in this!,

regards,
Vikram

Hi Vikram,

The answer to your question depends on the details of your scope. If your scope has the abilityto save the image to memory or floppy and allows reading same, you may be able to pull this off using gpib, if your scope is so-equiped.

Otherwise you will have to resort to readingas much as you can and simulating the screen using LV.

If you need help with VISA you should post to that list.

Hi Ben,
I have another question. I have been successful in finding 3rd party software for capturing the exact sreen of the oscilloscope. The question is that in Labview can I execute/run this 3rd party software after getting the waveforms on the scope. what exactly I mean is that I run the VI , obtain the waveforms and then in the same block diagram I define some Icon which actually runs/executes the 3rd part software downloaded by specifying the location of the software(say in C:\3rd party software)
Hpoe I am clear in what I mean here.

thanx,
Vikram Malik

Hi Vikram,

It depends to large extent on the 3rd party software.

If they provide a,
Command line interface,
DDE interface,
Active-X interface

it should be do-able.

Another thought;
If the 3rd party code can do it, you should be able to do the same thing in LV.

Get the manual for the scope,
or
Use NI-Spy to figure out what commands are being sent to get the image.
