Oscilloscope Average Acquisition and AC Triggering

When seeing small signals with the oscilloscope, noise can corrupt the signal and measures can not be made.

Using the Average Acquisition Mode present in all modern digital scopes can be very helpfull when the noise is not correlated.

A nice trick when using average acquision with small AC signals is to use the trigger in AC coupling mode. This will prevent misstriggering becasue of small DC offsets of the front-end. ... https://www.youtube.com/watch?v=vvC-Pw8E1os
