noise_check
Purpose:
-
Statistical evaluation at input channels
Enter:
-
noise_check <number_samples> <channel_list>
Where:
-
number_samples
Specify the number of samples to be collected.
channel_list
Specify a list of the channel numbers to be sampled.
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 range of analog input channels in millivolts.
This process runs repetitively until cancelled with a Ctrl-C. The data is sampled at the fastest rate supported by continuous analog input, normally 20 Hz.
For the data to be meaningful, the channels should all be specified to have the “FAS” rate and should have 0.0 for the filter constant.
