Apologies for the delay, I am working remotely and didn't have access to the correct scope. I have now confirmed the issue and it is a driver bug which I have raised with the development team.

As a first look the PicoLog traces are greatly zoomed on the vertical axis (120uVolt) when compared to the PicoScope traces (10mVolt) so the noise automatically looks bad. I would also suggest sampling at 1msec per channel in PicoLog and select "Latest Sample" and not "Average" to see what you get a...

I would change the math channel 60/((1/freq(A))*2) to 30*freq(A) which is the same. The reason you are getting the crash is that at the very start of the trace the frequency is unknown as there haven't been the crossing points to determine it, you will see no trace in the math channel plot. And if y...

I would be keeping an array of device handles that are assigned when you open the units and then use these values for the close unit calls.

Actually I can see the issue you have, the 20200708-0001.psdata file I had originally loaded for comparison was the earlier one you sent through not the second one. I will need to test this against a real scope tomorrow.

If I step through those files each buffer in turn is different from the previous one, and if you compare file to file the same numbered buffers are different, so I am still at a loss in seeing what you are. One point when you run again are you are allowing it to fully capture the 1000 buffers and st...

The waveforms in the file you sent look perfectly feasible for a rapid block capture with those trigger settings.

What makes you say they are from the previous run ? can you make a short video to highlight the issue.

If you use the waveform buffer tools highlighted you can step through the 1000 rapid blocks that you have captured

Can you post a psdata file for your rapid block capture where you only get the first waveform so we can take a look at your setup.

Firstly make sure that Tools->Preferences->MaximumWaveforms is set to a value >= to the number you wish to collect using rapid trigger. Then try a normal repeat trigger and what you will see is the waveform count at the top increment buffer by buffer as the scope triggers, displaying the last collec...

Example code is available on https://github.com/picotech in different languages. You will need ps4000a ones for the PicoScope 4824

One question before you go down this route, how many channels of data collection do you need and at what desired sampling rate ?

You need the ps2000a examples for the 2207B, not the ps2000 ones.

I have removed the link to the video.

Do not use passive probes for mains measurement, it is dangerous. You will probably damage one or more of the probe, the scope, the PC, or yourself.

You need to use appropriate CAT rated differential probes or an isolation transformer.

As you are now in touch with support@picotech.com directly we will handle the issue through your support ticket, with a possible RMA

Sorry for the delay in responding due to the current situation.

Can you please email a Picolog data file to support@picotech.com and one of the team will be able to look at your issues.
