9.2 Performing Synchronization
WF1967/WF1968 9-5

Performing synchronization
Synchronous operation is performed in the master unit.
When the phase synchronization is run, a message is displayed on each unit.

Phase relationship after synchronous operation
The oscillation phase for each channel is initialized by the synchronous operation. The phase
difference of the output waveform appears as the difference of the phase setting for each channel.
Even if you make a synchronous operation, changing a frequency later loses the synchronization
relationship. Even if the synchronization relationship is lost, no message is displayed. If necessary,
make a synchronous operation accordingly.
The synchronization relationship is lost when the connection cable between the master unit and slave
unit or between slave units is removed. If you change the setting of channel mode or external
frequency reference, the synchronization relationship is lost.

Operational restrictions
There are restrictions shown in the following table to the synchronous operation. Even if the
synchronous operation is invalid, making a synchronous operation causes all channels to stop the
oscillation once.
Item Restriction
Waveform Invalid for noise and DC
Modulated oscillation mode Invalid for FM and FSK
Sweep oscillation mode Invalid for frequency sweep. Invalid for gated single sweep.
Burst oscillation mode Invalid
Synchronous operation is performed in the
Utility screen of the master unit.
Select [
φ Sync] in the Utility screen, and
then press the ENTER key.
This runs the phase synchronization.
At this time, the phase will be discontinuous
temporarily because all channels stop the
oscillation once.
In the Utility screen, select
[
φSync] and then press the
ENTER key to execute the
phase synchronization
