5244A to measure PWM?

Post by jhoyle »

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.

Serial Number: CP897/024
USB Version: 2.0
Calibration Date: Tuesday, September 01, 2015

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.
