Oscilloscope multiple channel measurement

[arihant]

Hi all,

I am working on measurement and logging of peak value for two pulsed signals. The signals are connected to agilent scope DSOX 3034A for display and local measurement. The scope is then interfaced with PC using LAN interface for peak measurement of the signals. I have sucessfully carried out the programming to display them on Labview on PCusing drivers provided by Agilent. But I am only able to get peak of one signal but not the other even after trying quite a few logic combinations.

The vi is attached herewith. 

Can anyone suggest how to display and log both signals on a single chart and file respectively? It would be of great help.

Thanks

A Tektronix scope wouldn't have any problems with this...

You might want to play around with using Configure Measurement Type.  I'm thinking you will need to use that to set which channel the measurement is done with and then read the measurement.  Repeat for the other channel.

Alternatively, you could just use the Array Max & Min function in LabVIEW to calculate the peak-to-peak measurments directly from the retrieved waveforms.

Thanks for your response.

I tried to use configure measurement for multichannel display. It is working fine as long as only displaying the DSO screen to a remote PC is concerned. But I also need to get the peak value of both the signals whereas I am getting that for only one. The read waveform vi does not have channel selection option if I am right. I will check it once get back to my workbench.
