desired value by using the numeric keypad, the arrow keys, or the knob.
 Freq Deviation: indicates the frequency deviation between CH1 and CH2.
The relations among the parameters are as follows: F
CH2
=F
CH1
+F
Dev
(take
CH1 as the reference source); F
CH1
=F
CH2
+F
Dev
(take CH2 as the reference
source).
 Freq Ratio: indicates the ratio of the frequencies of CH1 to that of CH2. The
relations among the parameters are as follows: F
CH2
=F
CH1
*F
Ratio
(take CH1
as the reference source); F
CH1
=F
CH2
*F
Ratio
(take CH2 as the reference
source).
Note: Please set this parameter before enabling the frequency coupling
function. When the frequency coupling is enabled, this menu is grayed out and
disabled. You cannot set the frequency deviation or frequency ratio.
Amplitude Coupling
1. To Enable the Coupling Function
Tap the Ampl Cpl parameter selection field to select "On" or "Off" to enable or
disable the amplitude coupling function. By default, it is set to "Off".
2. Amp Coupling Mode
Tap the AmplCplMode parameter selection field to select "Deviation" or "Ratio".
Then, tap the Ampl Dev or Ampl Ratio parameter input field to input the
desired value by using the numeric keypad.
 Ampl Deviation: indicates the amplitude deviation between CH1 and CH2.
The relations among the parameters are as follows: A
CH2
=A
CH1
+A
Dev
(take
CH1 as the reference source); A
CH1
=A
CH2
+A
Dev
(take CH2 as the reference
source).
 Ampl Ratio: indicates the ratio of the amplitudes of CH1 to that of CH2. The
relations among the parameters are as follows: A
CH2
=A
CH1
*A
Ratio
(take CH1
as the reference source); A
CH1
=A
CH2
*A
Ratio
(take CH2 as the reference
source).
Note: Please set this parameter before enabling the amplitude coupling
function. When the amplitude coupling is enabled, this menu is grayed out and
disabled. You cannot set the amplitude deviation or amplitude ratio.
Phase Coupling
1. To Enable the Coupling Function
Tap the Phase Cpl parameter selection field to select "On" or "Off" to enable or
disable the phase coupling function. By default, it is set to "Off".
2. PhasCplMod
Tap the PhasCplMode parameter selection field to select "Deviation" or "Ratio".
