Re: Real time collection and analysis with Matlab

Thanks Martyn,
Back to my earlier question, is there a way to fix the sample number? Typically, the sample number varies greatly. for instance, ~200000 samples are sent, then ~3000, then ~200000 etc.

Re: Real time collection and analysis with Matlab

@ Benno: thank you for help, are you suggesting to use a circular buffer in Matlab? If so can you please point me to an example? @Marty: Thanks for your feedback. The data collected are voltage pulses from a photomultiplier tube. The pulse duration is typically 100ns, and I need to collect the signa...

Re: Real time collection and analysis with Matlab

Follow up: I'm running a modified version of PS2000A_ID_Streaming_Example for analyzing and plotting the stream of samples. It works but is there a way to maintain constant the number of collected samples? Data analysis would be a lot easier if the size of the sample were say 100xsample interval

Real time collection and analysis with Matlab

I need to collect a signal from a Picoscope 2208B and analyze it in real time with Matlab. Ideally the time interval has to be 100ns and I need to analyze ~1ms samples at the time and plot the results. It seems to me that this could be accomplished using the instrument driver with streaming data cap...

However, I get the following message when running PS2000_ID_Block_Example.m Warning: Disconnect: No devices found. Error using icdevice An error occurred while executing the driver create code. T...
