8.7 Keeping Frequency Ratio Constant (2-Channel Coordination, Ratio)
WF1967/WF1968 8-11
8.7 Keeping Frequency Ratio Constant (2-Channel Coordination,
Ratio)
If the channel mode is [Ratio], you can change the frequency with the frequency ratio between both
channels kept constant. In coordination with the change of frequency of the channel 1, the frequency of
the channel 2 is automatically changed.
The channel 2 coordinates with the channel 1 also during the frequency modulation or frequency sweep.
This function is disabled for the burst oscillation and gated single sweep.

Selecting 2-channel coordination

To set the frequency ratio
In the Utility screen, set [Channel Mode] to
[Ratio] ([Indep] is normally set).
This makes the channel mode an oscillation
with constant frequency ratio.
The frequency ratio between both channels
is kept constant.
This function controls to keep the frequency
ratio
constant also during the frequency
modulation or frequency sweep.
For the oscillation with the constant
frequency ratio, you cannot
set the frequency of the channel 2 directly.
Set [Channel Mode]
to [Ratio]
In the Oscillator screen, set the frequency
ratio in [Ratio(N)] and [Ratio(M)] of the
channel 2.
Frequency of channel 2: Frequency of
channel 1 will be N:M.
If you change the frequency ratio, the phase
will be discontinuous temporarily because
both channels stop the oscillation once.
Set [Ratio(N)] and [Ratio(M)] of CH2
