A sync signal is output according to the waveform or oscillation status. This signal can be used as the
oscilloscope synchronization signal.
As shown in the following table, the output signal can be selected according to the oscillation mode.
Table 3.1 Signals Selectable for Sync/Sub-Output
Oscillation Mode Selectable Output Signal
All 50% duty TTL level logic signal that rises at zero phase position of reference
phase of waveform output (hereafter, reference phase sync signal).
The phase relationship with waveform output can be changed.
