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...

trouble connecting to picoscope with Matlab

I setup Matlab for capturing data from picoscope 2208B. Installed PicoSDK and PicoScope Support Toolbox. 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...
