Why does the spectrum intensity changes when I move a 20 kHz pulse in the scope window.
Spectrum intensity is maximum in the middle of the window when pritrigg is approx. 50% and that at least the end and beginning of
SCOPE window even though the entire signal is in the scope window.
I use to PicoScope6 3224.

Hi can you send a psdata file or settings file and screen shot if the data file is too big.

Kind regards

Excuse the late reply.
I have found the error.
I thought that during the election window function, flat-top was the last election.
I would later find that there was an additional weighting 'Rectangular' which solved the problem.
