Wavforms stops recording at 4098/5000 average

[nickdorogy]

I have recently encountered a semi-reproducible issue averaging data with the Waveforms app. I am recording data from my ADP3450 using Waveforms V3.22.2. I am saving 512Ki samples at 1E8 Hz (so a total of 524288 samples). I trigger on an the ch1 input, record both ch1 and ch2 and stack over 5000 samples. This amount of stacking is necessary to sufficiently improve SNR, so I do not think I can reduce the total averaging. More than half the time I try to record, the averaging gets stuck at 4098 samples (specifically 4098, not any other number) out of the 5000 total desired samples. The app does not freeze and I can still toggle windows or navigate, but it never updates from the 4098. I have the oscope connected via USB.

Any suggestions on what might be causing this problem or how to track down the issue?

Hi @nickdorogy

Could you provide some screenshot on what you are doing ?

The following seems to be working for me, 1000 average of 5000 samples:

@attila Certainly. Attached here is an example, although you can see that I am averaging over 2k samples instead of 5k samples since I cannot get 5k to work. Also, I want to clarify that I am collecting 512Ki samples and averaging over 5K.

Hi @nickdorogy

I still don't see the problem

@attila As I mentioned, it is a semi-reproducible issue even for me. If I let the data collection run for the full 5k average it gets stuck at 4098, but this issue is inconsistent.  I can attach a screenshot showing 4098/5000 samples averaged but I am not sure how much help that would be. Ive checked the temperature and I don't see any issues there either which is why I am uncertain of the root cause. Is there a log I could download that might provide further info?

Hi @nickdorogy

Have you tried the latest software version ?
