I found out how it has to be used. So now basicaly i do not have to use all the settings that have to deal with ranges. for(i=0;ihandle, userProbe...

Yes and it dones't work.

Yes, the ps4000aSetProbeInteractionCallback function populates the values of userProbeInfo.userProbeInteractions . I can get access to them and obtain for example rangeFirst_ which in this case returns 6003 but can not be established as a value range inside ps4000aSetChannel . Also when the call to ...

I did not find a solution, ps4000aSetChannel() does not accept values like PICO_1KV_500V or 6010 . I kind of hardcoded the range so when I make a plot from the csv values the signal has the same shape as the one from the software. For example to use the 500V for the 442 differential probe i set the ...

Is there a way to just tell the unit that I want to use a connected probe without handling errors? Could I pass a null pointer to ps4000aSetProbeInteractionCallback? [/size] I recommend you to use the available c example and forget about python. You just have to run the ps4000aCon.c file and works ...

I have a picoscope 4444 connected with a TA300 current probe and an 442 differential probe ,to be able to make current and voltage measurements. On the programmers-guide PDF it is specified that the range is defined in the header file : PICO_STATUS ps4000aSetChannel ( int16_t handle, PS4000A_CHANNEL...

Streaming mode with python looks like is not available for now.

Hi

We are currently looking into implementing streaming mode for Python and will be generating examples for streaming mode soon

Any news?

I'm trying to use ps4000aGettimebase(). With this function i can specify the number of samples and the time interval between readings. Can this be used in streaming mode?
I know that I can specify the time interval between readings when I call ps4000aRunStreaming() but not the number of samples.

My question is the following: I am running the 4444a in streaming mode and I want a reduce the number of samples , how can be made? In this case I want 1 sample every 250ms,during a long period of time. uint32_t sampleInterval=250 ps4000aRunStreaming(unit->handle, &sampleInterval, PS4000A_MS, preTri...

Thank you

I am also having problems with streaming in Python. I'm stuck with the callback function. First I defined the callback function as: @CFUNCTYPE(None, c_int16,c_int32,c_uint32,c_int16,c_uint32,c_int16,c_int16,c_int32) def callBackStreaming(handle,noOfSamples,startIndex,overflow,triggerAt,triggered,aut...

Where do you problems with https://github.com/jbentham/picostream ?
