Re: Averaging signal before tranfering data from buffer to PC

Hi,
No this cannot be done by the scope. All the waveforms have to be transferred to the PC and averaged.

Resolution enhancement / moving average filter

This is how 'Resolution enhancement' works- If you collect the following data samples from the scope- s1,s2,s3,s4,s5,s6,s7,…..,sn For ½ bit you replace each sample with the average of two values (s1+s2)/2, (s2+s3)/2, (s3+s4)/2, (s4+s5)/2, (s5+s6)/2, (s6+s7)/2, (s7+s8)/2,……, (sn+s(n+1))/2, For 1 bit ...

Averaging N waveforms, for repetitive waveforms

Just sharing a LabVIEW code snippet here for returning an average shape of a repetitive waveforms, over N captures.
It can be directly used with our block examples.
If you wish to use a current streaming example with you need to create a circular buffer that returns a fixed number of samples.

I have created this Advanced triggers document as general guide in to help configure them.
I hope to add more examples when I get time.

Re: Install error for picoscope/stable,stable 6.14.36-4r5676

Hi,
I have created a bug for this seems to affecting Debian systems. (amd64 and armhf packages)
I have added rpm packages may also be affected.
For now you can install with the work around for Debian systems, full instructions here-

Re: Use of GetTimebase function

Hi Aaron, I have just looked at the ps5000aGetTimebase in the related Programmers guide. It seems to clear that *timeIntervalNanoseconds and * maxSamples are outputs and the other variables inputs to the function. It also has the same statement relating to internal overheads. If you are relying on t...

Re: Streaming Mode trigger reset

Hi, Continuous streaming is limited to 80 MS/s per channel using the API, or 160 MS/s total shared across all channels. So for all 8 channels that only 20MS/s. Slower than block mode at the fastest time base. You may get PICO_STATUS code returned if set the sample interval above this transfer rate f...

Re: Generator Frequency rounding issue

Hi, How does this compare to setting the frequencies in Picoscope 6? I assure you are using a sine wave as this would rule out rise time limits of the AWG. I would try setting up the AWG with a one cycle of a a sine wave in the buffer. And call SetSigGenArbitrary() Calculate the deltaPhase value usi...
