Hi, I'm trying to understand the true acquisition rate per channel in our system.
From page 69, I understand that the set acquisition rate of the device is divided down per the channels used:
Our configuration (via LabVIEW):
3AI, 1AO
Analog Inputs:
We create AIN tasks for Channels 0-2 (differential)
Range +/-10V
Channels 1 & 2 have gain set to 8; Channel 0 has gain set to 1
Timing is setup as:
Internal Clock
Continuous Samples
Sample Frequency 12kHz
Samples per channel: 1200
Number of buffers: 100 (I would like to note that I was unsure of number of buffers as a setting and welcome any feedback in that regard)
We periodically read this data DtOlReadMultiple2D which provides 1200 data points for each channel
Analog Outputs:
We create AOUT tasks for Channel 0
Range +/-10V
No explicit timing setup, we simply start the task
When needed, we issue a 1Chan 1Sample command to write to our output via Channel 0 (we apply 0/5V to a magnetic door lock)
I want to confirm that the AO does not count toward the input channel-gain list count and that we have a total of 3 inputs within this input channel-gain list (Ch 0 - gain 1, Ch 1 - gain 8, Ch 2 - gain 8). Meaning the sample rate for each of those inputs is 12000/3 = 4kHz.
Thank you for your help.
