noise_check

Purpose:

Perform statistical analysis on specified analog input channels, calculating and reporting mean, standard deviation, minimum, maximum, and variance based on collected samples.

Enter:

noise_check <number_samples> [channel1 [channel2 …]]

Where:

number_samples

Specify the number of samples to collect per channel.

channel1 [channel2 …

Optional. Specify one or more channel numbers to sample. If omitted, no data will be processed.

Example:

noise_check 100 0 1 2 3 4
The above command takes 100 samples of channels 0 through 4 and reports the statistics.

Notes:

Reports mean, standard deviation, minimum, maximum, and variance of analog input channels. This process runs continuously until interrupted, sampling data at the system’s configured rate for meaningful results.
