MCC USB-2404-UI: 'a_in_scan' returning incorrect values

[vkane]

I am trying to get measurements from my DAQ as fast as possible. I am tyring to do that with a_in_scan(). But a_in_scan() does not agree with a_in_32() or v_in().

Am I using a_in_scan wrong? How do I get data at the kHz logging speed?

There are three versions in the USB-2404 series: the -UI version you have and the -10 and -60. Only the -10 and -60 can reach kHz speeds, while the -UI version maxes out at 100 Hz.

Why does a_in_scan report different values than a_in_32?
