Coupling Set
DG1000Z supports frequency, amplitude and phase couplings. Users can set the
frequency deviation (frequency ratio), amplitude deviation (amplitude ratio) or phase
deviation (phase ratio) of the two channels. When coupling is enabled, CH1 and CH2
are mutual base source. When the frequency, amplitude or phase of one channel (as
the base source) is changed, the corresponding parameter of the other channel will
be changed automatically and always keeps the specified frequency deviation (ratio),
amplitude deviation (ratio) or phase deviation (ratio) relative to the base channel.

Frequency Coupling
1. Frequency Coupling Mode
Press FCpl Mode to select “FreqDev” or “Ratio” and then input the desired
value using the numeric keyboard.
 FreqDev: the frequency deviation between CH1 and CH2. The parameter
relations are as shown below:

 Ratio: the frequency ratio of CH1 and CH2. The parameter relations are as
shown below:

Note: please set this parameter before enable the frequency coupling function.
When frequency coupling is enabled, this menu is grayed out and disabled and
you can not set the frequency deviation or frequency ratio.
2. To Enable Coupling Function
Press Freq Cpl to turn frequency coupling “On” or “Off”. The default is “Off”.
Amplitude Coupling
1. Amplitude Coupling Mode
Press ACpl Mode to select “AmplDev” or “Ratio” and then input the desired
value using the numeric keyboard.
 AmplDev: the amplitude deviation between CH1 and CH2. The parameter
relations are as shown below:
