NI 5112: How to set number of averages for array measurement

[JE]

Hello,

I have a NI 5112 card.  There is an array measurement called Multi Acq Average.  If I understand correctly it is a running average.  Does anybody have an idea on how to set the number of averages?

Thanks,

Jerome.

Jerome,

You are exactly correct, it is in fact a running average which calculates a new result each time that it is called.  This means that the "number of averages" will correspond exactly to the number of times you call it (minus one since the first time it will just return exactly the data that was acquired).  The average array is cleared by calling niScope Clear Waveform Measurement Stats with the measurement function parameter set to Multi Acq Average.

This information is located in the NI High-Speed Digitizers Help, which is in your Windows Start menu and also downloadable here.

Thanks,
