In continuous mode, there are two parameters that need to
be specified:
Sampling rate
Specify the sampling rate of each AI channel. Since the
U2300A series DAQ devices comes with multiplexing
analog input, the maximum sampling rate depends on the
ADC's sampling rate and the entry number in the scan
list.
For example, if four channels are specified in the scan
list of the U2356A, the maximum sampling rate is actually
500 kSa/s divided by four, which is 125 kSa/s for each
channel. However, in the U2331A, the maximum sampling
rate is only up to 1 MSa/s when switching of multiple
channels is enabled.
Sample points
Specify the number of acquisition points for the channel.
For example, if 800 sample points and four channels are
specified in the scan list, there will be total of 3200
samples to be acquired.
The maximum sample points for single-shot acquisition are 8 MSa and for
continuous acquisition is 4 MSa, where both types of acquisitions are of
continuous input mode.
