Hi. I'm new with Pico but I noticed one thing I cannot explain to myself. I measure one signal each time with pico 4425 (a glitch in the electric piano) and at different settings i measure different frequency pf the glitch and IRL it is the same each and every time. I attach 3 files - 1 villion samples, 3 million, and 3 million longer time base and the frequency measured with rulers is different every time. What am i doing wrong? Thanks.
