How to capture entire display of oscilloscope DPO 4054 as screenshot.

[Sagar Tidame]

I am developing one labview application for testing. in that i am fetching the display data of oscilloscope in Labview in waveform graph. but i am not able to fetch entire display of oscilloscope like cursors, measurment values etc. i have already downloaded instrument driver from ni site for DPO4054 oscilloscope.

please guide me how i can capture entire display of osciloscope as screenshot.

Hello,

If you are looking for a autonomous screen capture of your waveform using labview, it can be done as per the following link: http://vi-lib.com/user.lib/HowtoperformScreenCapture.html

Hello Sahil

I am looking for the same solution. I would like to capture a screen shot of the osciloscope front panel and save it as a JPG. I do not want to read data from scope, then disply it on my LV front panel to capture a screen shot of my LV front panel. The solution you suggested work just like that, capturing LV front panel, not scope front panel.

Is there a way to transfer the scope screen shot to LV and via LV save it on PC hard drive?

Thanks

Tom

All the features you need can be recalculated from the data, or you instruct the scope to store a screendump and then transfer the file from the scope,

This procedure is not implemented in th driver because a screenshot is less easy to use than the data when calculating.

Furthermore it takes a whole lot of time to transfer the picture. Calculate yourself the number of bytes transerred for both cases.

But it has been done in LabVIEW and maybe you find an example in the forum.

Yes, if you want the screen shot from the oscilloscope, you have to recalculate the data and generate the screen shot again, or if your oscilloscope permits, which can be checked from the vendor or the data sheet, store the screen dump and transfer that file to LabVIEW using VISA.
