I have found 2 options to trigger 1 for entring and 1 for exiting.
but not a option to trigger on both situations.

The PSDATA files are these 2. https://www.ans-net.nl/picotech/exCHBstarttransmissions.psdata https://www.ans-net.nl/picotech/exCHBendtransmissions.psdata The end of transmission is not a big problem but triggering on the start and the end looks challenging. Maybe someone from picoscope can tel somet...

Ok I got the files

Can I publish them here on the forum so the people can also have a look at them ?

Looks like some form of QPSK.
Are there stuff bits in the signal ?
So the longest time the signal is below 50 mv is always less than e.g. 64ns.

You can see it from the yellow diamond or the % value at the bottom of the screen. See the red arrows for the trigger point.

The capture time in the property's screen is the time the capture is finished. So trigger time + the time of the waveform after the trigger point. e.g. you have a time scale of 1 sec/div (10 sec whole trace) and the trigger is alt 20% of the image then the capture time would be (100-20)=80% * 10sec ...

My main expertise is in C and C++.

I even can not tell you if MATLAB is fast enough to do tis at 10M values per second.

I know C and C++ can do it with ease, there are always programmers that can even produce code that even C is too slow

Can you post a .psdata file ?

Dit you install the latest updates from Windows and .net ?
Also the latest updates for the video drivers ?

I have seen this sometimes in the past when there are math channels in view, or internal data was corrupted (2015 or so, a long time ago)

With the SDK or with the PicoScope 6 / 7 software ?

Double buffering is the only solution I could think of. Everything you receive you put in a ring buffer, at least 2 or 3 times the number of samples you want. When there is enough data in the ring buffer you take the samples you want and analyze them. The extra samples you leave in the ring buffer f...

You can try running a program that wait x seconds and then stops executing.

On Linux / mac "sleep 5"
On windows "powershell start-sleep 5"

Both options wait 5 seconds.
I don't know if picoscope waits for the program to exit, if not then this is no option.

The decoding of CAN signal is not in the SDK

Time measurement should be no problem.

Example code see below.

I had done the same measurements to compare different types of current clamps and a 0.1 ohm shunt. Below the rise times of various clamps v.s. shunt (TA300 can be compared to the TA189 I think) current clamp rise-times.png Below the fall times of various clamps. current clamp fall-times.png The ring...

You can not have the picoscope software running while you are using the SDK.
