8.5 Maintaining to Same Frequency (2-Channel Coordination, 2-Phase)
WF1967/WF1968 8-7
8.5 Maintaining to Same Frequency (2-Channel Coordination,
2-Phase)
If the channel mode is [2Phase], you can change the frequency with the frequencies for both channels
kept the same value while the synchronization relationship is kept. 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

Changing phase difference between channels
You can set a phase for each channel in the Oscillator setting screen. The phase between channels
appears as the difference for each phase setting.
Normally, set the phase of the phase reference channel (for example, channel 1) to 0 degree and
change only the phase setting of the channel 2. At this time, the phase setting of the channel 2 is a
phase of the channel 2 based on the channel 1. As shown in the figure below, if the phase setting of the
channel 2 is positive, the channel 2 precedes the channel 1 and if it is negative, the channel 2 lags
behind the channel 1.
In the Utility screen, set [Channel Mode] to
[2Phase] ([Indep] is normally set).
This makes the channel mode an oscillation with
2-phase.
Frequencies for both channels will be the same
and the phase synchronization is automatically
run. Even if changing the frequency, the
synchronization relationship is kept.
This function controls to keep the synchronization
relationship with the same frequency also during
the frequency modulation or frequency sweep.
For the 2-phase oscillation, the setting relating to
the frequency can be set only for the channel 1.
