When I use normal block-mode with simple triggering, the 2205A has no problem in recording pulses with 25MHz and transferring the block of data to the PC, before rearming again. But with the 2208B (which is supposed to be faster!), I can't even get close to that. From 100 pulses (even at 25MHz!) it ...

Model is 2208B (2000-A Series) When I call ps2000aGetNoOfCaptures() without the trigger ever being triggered, "nCaptures" still shows a value greater than 0! Is this the expected behaviour? I thought it would return only the number of actually captured segements, but there can not be any, if the tri...

Thanks so much for the clarification.
I'm actually just happy to find out, I'm not the only one mislead

Also a little bumped here :( We just got two 2208Bs as I thought the Offset would provide what I now know it doesn't, after reading through threads for quite a while :? The dilemma is, that all I had before was a call to get system ticks (which isn't accurate at all but at least something) and now (...

Hello!
I am trying to get Rapid Block mode running in C# with a 2208B, but the GetValuesTriggerTimeOffsetBulk64 method was not included in the Imports-class.
Is there any way to get the times for a bulk recording in C#?
Thanks!

P.S.: It seems to be available in the python examples.

Ah yes, the unsafe-scare :) I totally forgot about that. Good point… But as I understood it, there's actually more difference between pinning via GCHandle and fixed segments. THE Hans Passant has an interesting answer over at SO, but I am not knowledgeable enough about G...

I'm curious what the decision was, not to use the "fixed" statement here, as it would make "unpinning" of the arrays unnecessary and we could just use regular GC routines.

That explains why I have no problems so far, without using the pinned arrays. The GC mode GCLatencyMode.Batch basically disables the GC

Hi bennog! Interesting idea. If I understand correctly, I would write a C function that does 'something' (like iterating, maybe) over the arrays, and that function, should start to see discrepancies, right? If I put increments of 1 in the arrays and check on the C side, data would get discontinous. ...

Hey Martyn, thanks for the answer! I am using unpinned arrays for a while and have not encountered a problem even once. So I am wondering now, how one would go about writing tests for this scenario :wink: But that's a question for a different forum, I guess :D BTW, the quality of your products is im...

Hello everyone! Quick question: In the API examples for the 2000A-Series (possibly others, that's the one I know so far :D ) the arrays passed to the GetValues and GetTimesAndValues methods are pinned (PinnedArray) and have to be fully initialized beforehand. Why is this necessary and in what situat...

Hi!
I have a different setup and hardware (2205A), but am also struggling with a kind of similar behaviour, where the trigger will fire at falling edge when it is configured to trigger at rising edge. Really strange.

Hello Martyn and thank you for your wonderful answer, although I was already aware of these links. I got it all working in VS2019, VS2022, VS Code, on PC and Pi, with C and C# 8) Basically I tried all the (sane) combinations even cross-compiling and remote-compiling (only for C). :D What I meant is,...

Thanks, that's what I thought.
Have a wonderful rotation!

TL;DR: Has anybody successfully compiled the picoscope c/c++ examples in Visual Studio >= 2019 ? How?! --- Hello fellow scopers :-) I am struggling to get the c/c++ example code to work on a Win10 machine with Visual Studio. Is there any tutorial or walk-thourgh, on how to get the picoscope (2205A i...
