Can I save to psd only the part I am zooming in to?

First of all, I'd like to save on trigger at a speed of 100-200Hz. I have an external trigger at 150Hz at the moment. If I save, say 2000 files this way, it takes about 2 minutes to save the 2000 files. This gives me one file in about 60ms. Is the speed of save on trigger somehow limited? While the ...

Hmm, this is mysterious.

I decided to try once more and deleted the previous version of picoscope and installed the latest software version. Now it works.

psd -file format

I've been trying to make a matlab-code that would read psd-files. I am having slight problems with the code and I came here to ask, if I have understood something wrong. (I have a picoscope 3206 and the software version is 5.13.3) I use the save on trigger mode. I have also changed the SaveUncompres...

Save on trigger won't work on 5.13.9 (works on 5.13.3)

The save on trigger - mode will only give a 100 warnings (I haven't modified the psw.ini -file) when I try to save files. This occures with the latest software package, 5.13.9. I had the older version (5.13.3) of the software on a cd and with that, the save on trigger works fine. (All the settings a...

Thanks for this matlab-code! Any ideas on how to make the code run faster? This for-loop is the greatest time consumer. Would it be possible to change this for loop to some other form? for p=1:param.no_of_samples %here the samples are read t(p)=fread(fid,1,'uint')'; %time U(:,p)=fread(fid,param.no_o...

Fast block mode freezes

I'm using a Picoscope 3206 and I am struggling with the fast block mode (software version 5.3.19). I have the external power connected: The parameters I have for the fast block mode, are: Timebase: 20ns and the number of samples: 1M. Only channel A is being used (AC-coupled, +/- 1V). Additionally I ...
