Then, tap the Phase Dev or Phase Ratio parameter input field to input the
desired value by using the numeric keypad.

Phase Deviation: indicates the phase deviation between CH1 and CH2. The
relations among the parameters are as follows: P
CH2
=P
CH1
+P
Dev
(take CH1
as the reference source); P
CH1
=P
CH2
+P
Dev
(take CH2 as the reference
source).

Phase Ratio: indicates the ratio of the phases of CH1 to that of CH2. The
relations among the parameters are as follows: P
CH2
=P
CH1
*P
Ratio
(take CH1
as the reference source); P
CH1
=P
CH2
*P
Ratio
(take CH2 as the reference
source).
Note: Please set this parameter before enabling the phase coupling function.
When the phase coupling is enabled, this menu is grayed out and disabled. You
cannot set the phase deviation or phase ratio.
Trigger Coupling
Tap the Trig Coupling parameter selection field to select "On" or "Off" to enable or
disable the trigger coupling function. By default, it is set to "Off".
When enabling the output of the two channels at the same time and enabling the
trigger coupling, if one channel executes the trigger, then another channel will be
triggered automatically.
When the corresponding coupling function is enabled, there will be a blue mark
at the left side of the frequency, amplitude, and phase of the two channels. As shown
in the following figure, the frequency, amplitude, and phase are in the coupling state.
For example, when the frequency, amplitude, and phase deviations are set to
"100Hz", "1Vpp", and "10°" respectively, and the frequency, amplitude, phase of CH1
are modified to "200Hz", "2Vpp", and "20°", then the corresponding parameters of
CH2 will be automatically modified to "300Hz", "3Vpp", and "30°". Switch to CH2 and
modify the frequency, amplitude, phase of CH2 to "200Hz", "2Vpp", and "20°", then,
the corresponding parameters of CH1 will be automatically modified to "100Hz",
"1Vpp", and "10°".
