What exactly do you mean by GPIA? I searched the forum and developer zone and could not a single reference.

PGIA perhaps?

That makes sense. Maybe we should ask Laura for a new search option - 'All possible combinations of the following letters'.

Sorry,

Not sure about the exact property you might be looking for. There is a Device property called Gains that I believe will return the available ranges for a board. I haven't had to use that. The ones I've used are the Channel properties called AI.MAX and AI.MIN. These will report the coerced maximum and minimum values for a channel. So, for example, you use the DAQmx Create Channel and set the min to -2 and the max to +2 and the only range that supports that is +/-5, the properties will return +5 and -5.

I know about Channel properties, but it doens not tell about the gain of the amplifier. Before his was available.

Sorry, the properties that I mentioned are the only ones I know about. What function did you use before to return the gain?
