• 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.
