CAUTION If a difference in potential exists between the grounds of the BNC
connectors, do not short circuit these BNC connector grounds, as this
may damage the equipment.
ATTENTION
En cas de différence de potentiel entre les terres et les connecteurs
BNC, ne mettez pas en court-circuit ces terres de connecteurs BNC :
vous risqueriez d’endommager l’appareil.

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.
