[:SOURce]:FM[1]|2[:DEViation]:TRACk?
This command enables or disables the deviation coupling between the paths (FM[1] and
Fm2).
ON (1) This choice will link the deviation value of FM[1] with FM2; FM2 will
assume the FM[1] deviation value. For example, if FM[1] deviation is set
to 500 Hz and FM2 is set to 2 kHz, enabling the deviation tracking will
cause the FM2 deviation value to change to 500 Hz. This applies
regardless of the path (FM[1] or FM2) selected in this command
OFF (0) This choice disables the coupling and both paths will have independent
deviation values.
