Note: when you select parameter coupling, appears at the lower left corner. When you select
signal tracking, appears instead.
1. Parameter coupling
Coupling of frequency, amplitude or phase. You can set the frequency deviation/ frequency ratio,
amplitude deviation/ratio or phase deviation/ratio of these two channels. The parameters of them are
the reference for each other. When you change the parameter of one channel, the parameter of the
other will adjust accordingly and keep the same deviation/ratio as the reference channel.
Deviation:=CH2-CH1

Ratio=CH2

Signal tracking in order, set up phase deviation. When you set the deviation, and the parameter of
one channel, the other one will adjust accordingly.
