Math channel for graphing pulse width

Post by MDuBois »

Hi everyone, I wonder whether anyone knows a formula for using a math channel to graph pulse width? My application is automotive related, I would like to view a waveform for fuel injector pulse width rather than just a digital measurement reading at the bottom of the screen. Fuel injectors are typically ground switched, so I would need to know how to measure how long the pulse goes low, then display that as a waveform. Thanks, Marc DuBois.

I have looked around and can't find an equation that would give sensible results and would be programmable as a maths channel in Picoscope.
