Trying to use the Averaging mode Acquisition with MSO 7054B and didn't find in scope manual a detailed description of the algorithm and parameters used for averaging: what is the formula of any point on the screen after triger? Probaly linear An(i) = An-1(i) + [Xn(i) - An-1(i)]/n is used and switched sometime to exponential (what equation).

Avgs parameter definition also confuses me. Help says : "number of triggers to be averaged together" while remote ref guide says:

"The COUNt value determines the number of averages that must be acquired."

What exactly means "Averages" above? - either display points or triggers? How the acquision restart after Count is reached?

How can we estimate the averaging time vs. triger period?

Will somebody please point me to a relevant material?

2. always linear

3. when it reaches the COUNT value, it just drops the first waveform from the memory, so the disaplyed waveform is always the last N acquisitions.
