Increasing PicoScope buffering capabilities

Post by dcamps »

Dear all,

I have a PicoScope 4227, and I was wondering if there is any way to increase its capture buffer capabilities. Right now the software can maintain up to 32 "buffers". I can decrease the sampling resolution in order to control how much time is captured in each buffer.

What I had in mind is whether it would be possible to tell the software to automatically save to disk each buffer once it is captured, and once the 32 buffers are full then simply continue overwriting from the first one (which would be already saved in disk).

Best Regards

Daniel

Hi you can increase the number of buffers by going into Tools->Preferences.

You can actually capture your waveforms straight to disk by using the Alarms Feature under Tools. You will need to change it from Beep "Save Current Buffer" and make sure it is enable or selected.

Kind regards

Hi,

I have tried the "straight to disk" version, but I don't know how to exctract all the measurement files if I want to convert them into csv. After 32 buffers, the counter stops, it saves something but afterwards there is only two files (the saved one and the one opened) and both has only 32 buffers. I have also increased the buffers in settings to 2000, but no difference. Can you, please, explain in details, what are my options here for capturing a long file, and saving them all in csv? It would be also great to have the timetamp for the whole measurement.

I have a Pico5442MSO and Picosoftware 6.

Kind regards,
Vince

Can you explain what data you need to capture, specifically

Number of samples
Sample interval
Number of channels

and then what you need to do with the data once you have collected it.

1 µs resolution (14 bit)
4 channels

I want to save an about 200 s long heating process, than analyse it.

Thanks,
Vince

I need to observe an induction heating process with 15 kHz. So:

1 MS
1 s intervall --> 1 µs resolution (14 bit)
4 channels

I want to save an about 200 s long heating process, than analyse it.

Thanks,
Vince
