8.6 Keeping Frequency Difference Constant (2-Channel Coordination, 2-Tone)
WF1967/WF1968 8-9
8.6 Keeping Frequency Difference Constant (2-Channel
Coordination, 2-Tone)
If the channel mode is [2Tone], you can change the frequency with the frequency difference 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 difference
In the Utility screen, set [Channel Mode] to
[2Tone] ([Indep] is normally set).
This makes the channel mode an oscillation
with constant frequency difference.
The frequency difference between both
channels is kept constant.
This function controls to keep the frequency
difference constant also during the
frequency modulation or frequency sweep.
For the oscillation with the constant
frequency difference, you cannot set the
frequency of the channel 2 directly.
Set [Channel Mode]
to [2Tone]
In the Oscillator screen, set the frequency
difference in [ΔFreq] of channel 2.
The frequency of channel 2 results from
adding this frequency difference to the
frequency of channel 1.
Set [ΔFreq] of CH2
