Settings for PWM signal averaged out

Postby greanie » Mon Jan 05, 2015 11:16 am


I am looking to see the effective or average voltage of a PWM signal. My PWM is controlling fet switching the voltage across a solenoid. To simplify my interpreting the data, I'd like to be able to see the PWM average which should correspond to the average voltage across the solenoid. I have done this before through the settings but can't seem to figure it out this time.

Two options to add an average

    Measurements->AddMeasurement will give you the option to add a numerical average

    Tool->MathChannels->Create and then add average(A) in the equation editor to give a graphical average
