hello,
I'm using code to record input along 4 different channels of an NI USB 6343. I'm using a single task and a AnalogMultiChannelReader then after a finite acquisition collecting the data with the ReadMultiSample(-1) command. However the input along the first channel always starts with a zero. This happens even if what I'm recording is set to a constant non-zero value and it always occurs on the first channel created even when I try switching this channel.
If I output the same square wave on every channel then I see an offset on the first channel (see attached image) which makes it seem as though this zero is being appended to the collected data. Is this a known behavior? Is there anything I can do about it?
Please help.
Thanks!
I didn't find the right solution from the Internet.
