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：CH1
Select Utility
→Channel coupling, the status is OFF, then select Channel coupling→ON→Coupling type
→ Parameter coupling in this order, you can set up parameter coupling: frequency, amplitude and
phase
Note: In frequency coupling, you can select OFF, deviation or ratio.
2. Signal tracking
Select Utility
→Channel coupling, the status is OFF, then select Channel coupling→ ON→Coupling type
→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.
