Re: Set range channel for probes ps4000aSetChannel()
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 ...

Re: Set range channel for probes ps4000aSetChannel()
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 ...

Re: Configuring a PicoConnectProbe through the API
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 ...

Set range channel for probes ps4000aSetChannel()
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...

Re: Reduce Sample Number in Streaming Mode
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.

Reduce Sample Number in Streaming Mode
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...

Python Callback Function Error
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...
