No good duty cycle messurement value.PNG
This is the measurement that I have made.


Hello,

I have problems taking measurements with the function Duty Cycle with our new PicoScope. The problem is that it is a signal taken of a coil wich produce an induction. It is a automotive signal of the EVAP. I think it take the Duty Cycle time of the induction peak and not the time of the actuation and deactuation of the signal. Can you help me with this?

Try Tools->MathsChannels and enable Invert A, and then perform the duty cycle calculation on this, it will be inverted so needs subtracting from 100 to give the value you require.

A bit of a work around, but I will submit a request to the team to add a threshold level to perform duty cycle calculations on.
