A typical acquisition might take 6 readings off of the 3000 Series board module as illustrated below. The
user determines the scan rate and the number of scans to take.
DaqBoard/3000 Series board Acquisition of Six Readings per Scan
Note
: Digital channels do not take up analog channel scan time.
In general, the output of each channel’s counter is latched at the beginning of each scan period (called the
start-of-scan
.) Every time the 3000 Series board receives a
start-of-scan
signal, the counter values are
latched and are available to the /3000 Series board.
The 3000 Series board clears all counter channels at the beginning of the acquisition. This means that the
values returned during scan period 1 will always be zero. The values returned during scan period 2 reflect
what happened during scan period 1.
The scan period defines the timing resolution for the /3000 Series board.
If you need a higher timing resolution, shorten the scan period.
