8.9 Obtaining Double Output Voltage(2-Channel Coordination, Differential 2)
WF1967/WF1968 8-14
8.9 Obtaining Double Output Voltage(2-Channel Coordination,
Differential 2)
If the channel mode is [Diff2], you can change the setting with the differential output of both channels
being kept. In this 2-channels coordination mode, the DC offset setting for channel 2 is the set value with
the reversed sign. In coordination with the change of setting of the channel 1, the setting of the channel 2
is automatically changed. Coordination is performed also during various modulations or sweeps. This
function is disabled for the burst oscillation and gated single sweep.
When the hot sides of CH1 and CH2 are used as the output, including DC, it is possible to obtain the
double amount of output voltage (however, the output impedance
is 100Ω).

Operational restrictions
The restrictions are the same as when the channel mode is [Diff]
.
In the Utility screen, set [Channel Mode] to
[Diff2] ([Indep] is normally set).
This makes the channel mode an oscillation
with differential output (DC is also reversed
polarity).
The frequency, phase, and amplitude
settings of both channels are the same and
the reverse phase waveform is output. DC
offset is also of reversed polarity. Even if
changing the various setting, the differential
output relationship is kept.
This function controls to keep the differential
output relationship also during various
modulations or sweeps.
For the differential output oscillation, the
setting can be set only for the channel 1
(behaves as the oscillator for one-channel).
