Oscilloscope/Digitizer persistence waveform

[emc2006]

Is it possible to have NI digitizers show waveforms with persistence such as Agilent and Tektronix benchtop oscilloscopes? I understand ZTec modular oscilloscopes have this function. I guess it can be progemmed using LabVIEW, but is there an off the shelf way of doing it?

Thank you.

Hi emc2006,

     When you are using NI Digitizers with NI-Scope Soft Front Panel you can save data and analyse later.

    But If you need datailed information about our NI Digitizers you can contact NI office of your region.

There is currently not a simple property or function that implements persistence for NI-SCOPE. Your interest in this feature has been passed along to R&D for future consideration.

You are correct that you would have the ability to program this feature in LabVIEW.  I would consider using an intensity graph. The x value would be your time, the y value the magnitude of your voltage and as you iterate through your waveform you would create the z values to show persistence of the waveform.  Shift reqisters can be used to keep track of the intensity from the previous iteration.

Hello Jennifer,

Thanks for sending my suggestion to R&D, maybe we will se this feature in future LabVIEW releases.

If I manage to implement this feature using the current LabVIEW version I will post a messege on the forum.

I wanted to do this and this was the only thread I could find on it - based on Jennifer's suggestions I managed the above
 persistence graph. I'm pretty pleased with the result, so I thought I'd share it.
