NF WF1946B - Phase Sync

5.5 Other settings
5-24 WF1946B
 Phase sync (
SYSTEM
: φ SYNC)
Operation is described for restarting the CH1 and CH2 output waveforms from a set phase so as to clarify
the phase relationship.
This function is used when the channel mode is INDEP or when multiple units are synchronized by using
the 1991 synchronizer option.
When the channel mode is changed, phase sync is processed automatically.
CH1 and CH2 waveform outputs in the INDEP channel mode when the phase is synchronized
(CH1 is 0 deg. and CH2 is 90 deg.)
Operation:
① Press the
SYSTEM
key, then use the and keys to produce the following display (φ
SYNC flashes).

② Press the
ENTER
key to engage phase synchronization.
Other:
• φ sync is effective in Normal oscillation mode. In other modes, the phase may shift 180
degrees and the values of the mark cycle and space cycle settings may change.
• The phase between outputs of units (channels) in synchronous operation is the difference
between the phase settings (PHASE) set for each unit (channel).
