[DCPower] Decouple nr. of points generated from nr. of points measured
I have a PXIe-4139. I want to generate a triangle sequence in voltage with a small voltage step, e.g. 1 mV. If the sequence lasts for 1 second, it generates 1000 points. But I don't want to measure 1000 points, 100 is enough. The problem is that I'm unable to decouple the generation from the measurement. Here is my attempt
I generate a triangle with 1000 points, with the source delay 0.001 for each point, the generation should last 1 second (1000 points * 0.001 second/point = 1 s). The fetching is done in 10 chunks of 0.1 s with an aperture time of 0.01 seconds. It fetches 10 * 0.1/0.01 = 100 points in 1 seconds (10 chunks of 0.1 seconds). But it doesn't fetch the entire waveform:
Is my request possible at all? Or is the sequence generation blocked by the aperture time of the fetching? I know I can simple fetch at the same rate as the generation and then average in post-processing, but it seems better to do it in hardware. What do you think?
