MTS Multipurpose Elite - Manual (Page 145)

• Sample rate - (Default) Specify the frequency at which data is acquired. For example, with a sample
rate of 1 Hz, the buffer acquires data points once each second.
The sample rate must be a sub-multiple of the system rate:
— If you are connected to a controller, the sample rate that you enter is automatically adjusted to be
the closest multiple of the system rate.
— If you are not connected to a controller, you can enter any value; however, when you do connect to
a controller, the application checks the system rate and automatically adjusts the sample rate to the
closest multiple of the system rate.
Sample Duration
Specify how much data is acquired:
Timed Samples - Specify the duration of time that the signals are sampled. This setting in conjunction
with the sample rate determines how many samples are acquired. For example, a timed sample duration
of 10 minutes with a sample rate of 1 Hz would result in 600 samples.
Continuous Sampling - (Default) the activity acquires samples continuously until it is interrupted.
Sample Count - Specify the total samples acquired. For example, specifying a sample count of 600 at a
sample rate of 1 Hz, the DAQ activity would run for 10 minutes.

Delta Level Triggering Overview
Delta Level triggering places the selected signal values in the buffer when the reference signal changes
by the user-defined delta value.
