EEVblog #662- How & Why to use Integration on an Oscilloscope

In this tutorial Dave demonstrates the seldom used and often little understood mathematical integration function available on your modern digital oscilloscope. And demonstrates a practical example use for it in accurately measuring the total power consumption of a microcontroller that sleeps and then wakes up and does some processing before shutting down again. By getting the total area under the current curve.

      Hi Dave, You should be able to set the MSO3054 probe input to convert the voltage from the uCurrent to a current (eg 1mV=100uA) That way all the waveforms will be in Amperes and the integrated calcs in Ampere*Seconds. Cheers, Kym

      I screamed when you used the marker on the screen! 🙂

      You can go all the way and even use the math menu to multiply that integral by (1A/1000V) to convert that uVs to nAs eliminate any silly human units errors.
