8 Commands
Most of the commands can only be performed when the data acquisition is stopped (See commands
stopacq and startacq). Keep in mind that this will corrupt any running schedulers as the direct command
interface bypasses the scheduler and the running Frog software. When operating the ENIGMA
signalprocessor with the Frog/MURAN software it is virtually never necessary to perform any of these
commands manually.

Noise sampling is performed by command 'noisesample'.
Parameters:

It returns the following values:
IoffsetH=<val> - Offset of horizontal I
IoffsetV=<val> - Offset of vertical I
QoffsetH=<val> - Offset of horizontal Q
QoffsetV=<val> - Offset of vertical Q
noisePowerH=<val> - Horizontal noise power
noisePowerV=<val> - Vertical noise power
