Channel Coupling


DG4000 supports to enable frequency, phase and amplitude couplings separately
or at the same time. When coupling is enabled, set CH1 or CH2 as the “base”
channel and set the frequency, phase or amplitude deviation of the two channels.
Then when the frequency, phase or amplitude of the base channel is changed, the
corresponding parameter of the other channel will change automatically and
always keeps the specified frequency, phase or amplitude deviation.

Press Utility at the front panel, use

to open the 2/2 menu page and press

Coupling to enter the channel coupling interface.


1. To Set the Coupling Base

Press Base to set “CH1” or “CH2” as the base source of coupling. Here, “CH2”
is selected.
Note that the coupling base can not be changed when the coupling function is
enabled. At this point, this menu is grayed out and disabled.


2. To Enable Coupling Function

Press Coupling to turn “On” or “Off” the coupling function. The default is
“Off”.
Press FreqCoup to turn frequency coupling “On” or “Off”. After frequency
coupling is enabled, use the numeric keyboard to input the desired frequency
deviation. Here, it is set to “100Hz”.
Press PhaseCou to turn phase coupling “On” or “Off”. After phase coupling is
enabled, use the numeric keyboard to input the desired phase deviation. Here,
it is set to “10°”.
Press AmpCoup to turn amplitude coupling “On” or “Off”. After amplitude
coupling is enabled, use the numeric keyboard to input the desired amplitude
deviation. Here, it is set to “1Vpp”.
