Scopy: can you do trace averaging?

Hi PRK ,

This has been a feature request for some time now:

https://github.com/analogdevicesinc/scopy/issues/824

but unfortunately it's not implemented yet. Also this discussion:

https://github.com/analogdevicesinc/scopy/issues/417

talks about some of the difficulty in aligning signals that have high slew rate. (That's part of the magic inside your favorite brand of benchtop oscilloscope.)

-Mark

Mark is correct about the need for trigger alignment. In the case of the M2k and Scopy the triggering is done in the hardware and will be aligned as well as the noise allows. There is also the possible issue of aligning on fractions of a sample period if you are looking at things that happen possibly between ADC samples, i.e. if a rising edge is as fast or faster than one ADC sample period. Up sampling / interpolation can help finding finer grained alignment of waveforms between raw data samples. I use this technique in the new Universal ALICE code and it works very well.

As to why it has not yet been added to the Scopy code is a matter of getting the attention of the developers to raise its priority in their to do list.

Thanks, if there is a way to help raise the priority, let me know. 

Yes, I am on to python and libm2k to try to do some trace acquisition etc.

Peter, you can always post another feature request on GitHub to see if that sparks a response from the development team.
