5244A to measure PWM?

Postby jhoyle » Tue Mar 15, 2016 11:45 am

Hi Everyone

Is there a way to graph PWM signal? I need to verify a 8-92% duty cycle signal. It is being generated at 500 hz I believe. It is an engine throttle control signal for ecu. I am just trying to verify the signal is ok.
A graph is ideal to show no fluctuations in the pwm output.

Thanks

Yes, there is a maths channel that will graph the duty cycle for you :D

Tools->MathsChannels->Create and then select Advanced button and you will see Duty as one of the options.
