oscilloscope and i want want to capture a screen shot(image) afte a particular trigger like high to low so, how can i do it by using scpi commands
You can save the screen image to disk using the :DISK:SAVE:IMAGe command, or you can get the screen image data using the :DISPlay:DATA? query.
There is an example of using the :DISPlay:DATA? query in the programmer's guide's "Sample Programs" chapter (see www.keysight.com/manuals/MSOS404A).
hey pat thanks for replying I am using :DISK:SAVE:IMAGe command to save image but I want it to happen after a change in one of the waveforms(like high to low ) so I want to know that there is scpi command for detecting and fall edge and then save image
Yes, you can use something like:
The programmer's guide's "Sample Programs" chapter also shows commands like this.
thanks pat ill try this out
What modifications do I need to make in the above mentioned program to automatically store voltage peak to peak values of a waveform for burst of triggers.
You can use the ":MEASure:VPP CHANnel1" command to add the voltage peak-to-peak measurement to the Results pane on the screen so that the saved screen image will show the measurement, and you can use the ":MEASure:VPP? CHANnel1" query to return the measured value to the remote program. For multiple triggers, you would put the :DIGitize, :DISK:SAVE:IMAGe, and :MEASure:VPP? in a loop for the number of triggers you want to capture.
Thanks for the reply Pat. I will work with your input.

I think I need to elaborate my problem. The oscilloscope I am working on is an infiniium S-Series DSOS204A. My objective is to store the Vpp of a waveform into a text file or excel( for further processing) in trigger mode. The trigger is at 10 Hz and I need to save Vpp for each and every trigger. I don't know what is the best way to do it. Any input will be appreciated.
I searched in internet and I learned that I need to implement some SCPI program. If this is the only way where will I get that program.
Thanks and regards
