NF WF1945B - Phase Sync

5-24 WF1945B
 Phase sync (
SYSTEM
: φ SYNC)
Operation is described for restarting the output waveform from a set phase so as to clarify the phase
relationship.
The function uses φ-SYNC IN, OUT (1991 synchronous operation option) to synchronize the operation of
multiple units.
Phase sync operation and waveform outputs of 1st and 2nd units (1st unit phase 0 degrees, 2nd unit
phase 90 degrees)
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).
