know that I was able to solve the problem,
it was all due to a `float` being casted

source buttons do something different than
the "or" and "transparent

app (see below), and I measure a constant
difference of 10 Hz among the whole range

problem could be. In principle the trigger
should be independent of the sampling speed,

normal users are advised to use the DRSOsc
oscilloscope.

which requires a minimum pulse width of 3-4
ns. I see that your pulses are only 1-2 ns

Thanks a lot.

I solved it.
