Re: Scope running, recording pages question

This depends on the number of samples on a single screen. in PS6 the max sample memory would be 100Msamples in PS7 it is 250Msamples (i think) This is for all channels together (so with 4 channels enabled you have 25Msamples in PS6 and 62,5 M-samples in PS7) so in PS7 if your width of the screen is ...

Re: Missing Edges

This is because the scope has to sample 2 divisions of data before it can trigger. So after transferring the previous trigger to the pc the scope starts capturing data again, and (in your case) needs to capture at least 2 divisions of data. (otherwise you can not see the 2 divisions of signal in fro...

Re: Will a picoscope fit my needs?

I have tested here with a 3404d MSO In streaming mode, If you set 5s/div then you can sample at 2.5 M-samples/sec (if you use 2 channels) When using all or digital channels this will be reduced to 1.25 M-samples/sec. so depending on you SPI bit speed you can or can not do this. If you use block mode...

Re: Picoscope with Raspberry PI

I was thinking about your problem but the problem using picoscope software is that if you use triggers and alarms to save the .psdata file, you will have a gap of data between the end of the capture and the start of te new capture where the data is saved. Also if the voltage drops for say 1 hour bel...

Re: Picoscope with Raspberry PI

A simple intel NUC is also an option. I regularly use this smal formfactor PC (115mm x 115mm x 35mm) you have a small i5 windows (10/11) based system that wil work with picoscope. you can get a decent i5 system for below $100 on ebay I don't know if the 2205A has level drop out trigger to test for 1...

Re: Pico 4262 Low pass and Bandwidth filter

Most pico scopes do this in software, after the sampling is done and calculated in the OS you use.
If they do this in hardware with custom bandwidths the cost of the scope would double or maybe tripple.

Re: Getting back an event when trigger happens?

Yes that is the reason my preferred language is C/C++.
If you know what you are doing you can do even protocol decoding Realtime while streaming.
Only downside is you can not save your data as .psdata file so you can look at it in picoscope software.

Re: Data TransferHi

I don't think 400mA will bring you succes. I know the 3000 and 4000 series will not start and function properly with 400mA.
Don't know about the 2000 series scopes.

Re: Getting back an event when trigger happens?

The scope you are using, and the mode you are using it in is capturing in the memory of the scope. If the trigger fires then the scope captures the number of samples remaining after the capture (if your capture is at the start then the full 22M samples) and only then the scope signals over USB to th...

Re: Getting back an event when trigger happens?

Something is not adding up in your story. if you set timebase 0 (500 MS/sec) your scope memory is 32 MSamples. In this case all the data should be read by the scope in less than 0.1 sec. So the 6.5 sec wait time is not correct or you are not sampling at 500MSamples/sec. If it really takes 6.5 sec yo...

Re: Saved Waveforms are Truncated

It looks like there is a bug in the CSV export. However there is a workaround for your problem for now. Save only the complete waveforms as .psdata file so save (1-2). Open this .psdata file and save to CSV (all waveforms) Then you have the CSV data, see attached compressed CSV file I made this way....

Re: Saved Waveforms are Truncated

Can you post a .psdata file of the truncated waveforms ?
