Hello forum users !

It's unclear to me : is signal generator (AWG) feature available on Pico 4424 ?
Thanks for your help,

Hi Martyn ! >>The decay would occur if there is a switch from DC to AC... OK, understood ! As a work around, I put a 500ms delay after setting channels and trigger and before calling ps4000RunStreaming: it works ! It's no problem for me if you want to take a look at the code. Just let me know. Thank...

OK, I've just tried what you suggested : no change. One could have expected this. Because when the input signal to be sampled is a +2.5Vconstant one, there are only two possibilities: - DC coupling and you get all samples @ +2.5V. - AC coupling and you get all samples @ 0.0 V. There shouldn't be any...

Hi Martyn, Thanks for your prompt answer. The application doesn't start in DC. To be really sure, I've hard coded coupling mode. I'm really talking of two different behavior of the *same piece of code* with either 32bits or 64bits compilation and SDK (ps4000.dll). I've attached the sampled result (i...

Hi forum users ! I wrote a C++ app that samples a signal that has +2.5V DC baseline and some AC pulses ( <400kHz ). I'm using a 4424 Pico with ps4000.dll (either 32bits or 64bits, see below) under Windows 10. The 4424 coupling is set to AC. I first used the 32bits SDK files, and the +2.5V baseline o...

Hi Hitesh, I wish you a happy Easter ! Back to problems... :? First I've isolated the issue, it comes from the call to ps4000RunStreaming : ps4000RunStreaming( Handle, &UsedSamplingPeriod, PS4000_NS, uint32_t(0), uint32_t( GLOBAL_PicoSignal_SampleNumber ), int16_t( true ), uint32_t( 1 ), GLOBAL_Pico...

Hi Hitesh, My application only calls streaming one single time for an 8s long acquisition. After this single streaming call, Pico is closed and data are processed by the app. I mean there is never , in parallel, driver data acquisition and application data processing . From my understanding, it seem...

Hi Hitesh, Thanks for your suggestions. 1- Delay I've tried the 10ms delay in the waiting loop : Pico is still crashing. :cry: 2- Copy Buffers This sounds unclear to me. I've followed instruction from "4000 Series Programmers Guide" on streaming ( page 16 ). I'm allocating one buffer for each used c...

Hi Hitesh,

Thanks for your prompt answer.

You mean the *whole* project src files ?
Its gcc, wxWidgets, CodeBlocks; will you handle this ?

Hello Support Team ! I’ve developed a Win7 32bits Picoscope 4424 streaming application that has been working like a charm for many years. Unfortunately, I’m struggling to port this application to Win10 64bits. The Pico 4424 is crashing (LED turns off) after a few second of streaming acquisition. On ...
