Re: PICO示波器参考波形积分问题

I have made a comparison between different methods of current measurement.
See attached .psdata file. Measured on a 1 ms pulse of 11A DC rising and falling edges are of interest for you.

Re: PICO示波器参考波形积分问题

can you post a .psdata via https://wetransfer.com/ Also the current probe works with hall sensors and thye have some opamps in it to amplify the output of the hall sensor, they usually have a bandwidth of around 10kHz so a delay of some sort is to expect from this kind of sensor. If possible you can...

Re: PICO示波器参考波形积分问题

Do you have low pass filtering on in the settings ?

Re: CAN BUS

Your CAN bus is unterminated and you see the retry messages.
Terminate at least at 1 end with a 120 ohm resister.
Preferred both ends with a 120 ohm resistor.

Re: trigger consecutive pulses

So streaming is no option because the pulse is 1uS is 1 sample at 1MS/sec and streaming you can get at most 5-10 MS/sec. How many samples do you want of the 1uS pulse and what is the variation in the 1 uS pulse width. What programming language do you use ? can you post a .psdata file from the picosc...

Re: trigger consecutive pulses

What is the time between the pulses ?

Do you want to use the SDK or the picoscope software ?

So you only want the data from when the pulse signal is high ?

Re: Strange behaviour when using 500s/div and zoomed in

Ok it has nothing to do with zooming. When completely zoomed out i get exactly the same below 1 sec before pressing the stop button 2023-02-26_11-43-04.png and directly after pressing the stop button 2023-02-26_11-43-15.png complete psdata is too big for attachment so here is the link. https://www.a...

black screen on remote desktop

When running PS7 on a remote desktop (headless) system the PS software starts ok and shows the waveforms. But after some time combined with a new Remote desktop connection the screen stays black. The software is running on triggers and still works and also save the files with a correct waves in the ...

Re: How to set resolution enhancement by using Python --Picoscope 4425A

The option Martyn described will give some delay to your signal compared with the not enhanced channel data. Beter option is to take the average of your sample and 127 samples before your sample and 127 samples after your sample. This will give the same effect without the delay in the enhanced and n...

Re: How to set resolution enhancement by using Python --Picoscope 4425A

In the PS software this is done in the software so you have to program this yourselves.
You can do this with a moving average function.

Re: Problem with the digital highpass functionality

your sample rate is far to lo.
you should sample at least 5 times the frequency of the input signal.
So in your case you should be sampling at least at 1MS/sec.
