Time Delay measurement with Tektronix TDS5034B Scope

[jgmh]

Im trying to do a Time Delay measurement between two TTL signals on the TDS5034B O-Scope. Manually I am able to do it on the scope (Measure -> Time -> Delay). With LabView I am successful in communicating with the scope as well as doing most of the things I found in the Library. But I am not able to see where I can do the delay measurement with LabView. I want to use the O-Scope's internal functions with LabView to record the delay at a specified interval of time (i.e. record the delay every minute for ten minutes).

Please let me know if there is a VI or similar that will be able to do this.

Thanks,

John

John,

I assume you are using the driver available at http://sine.ni.com/apps/utf8/niid_web_display.download_page?p_id_guid=1CCC03EAE2B94BFDE0440003BA7CCD... ?

If so, included in that driver are all of the functions that we have that are specific to that device.  If there is something that is not in that driver that you would like to do, you will either need to program it yourself, or it may not be possible with that particular device.

I thought I would Hijack this thread and ask if this is possible to do this with the NI-Scope PXI 5122, I have started to develop a LabView VI.

This works in that it will display the signals on the graphs, but I am unable to think of a way of measuring the delay.

I am going to measure power supply delays, so I will be looking for a voltage of 4.9 and 3.2.

Thanks.

Mike.

Yes, it is possible to measure the time delay between two signals using NI-SCOPE.  You would use the niScope Fetch Measurement VI, and select Time Delay as the Array Measurement.
