Azelio,

thanks for the link but I already know this manual.

of 56,3 kHz at a timebase setting of 5µs/div.
If I am changing my timebase to 10µs/div and measuring the frequency I am getting
65,4 kHz.
This is a little bit confusing and seems to be reasoned from the little signal 
level...

So now I am more curious what signal the ESEC seems to be
