4. BASIC OPERATION
f) Tostartautoburst→Automaticallystarts
When, in the auto burst mode, the mode is set to the burst oscillation mode, burst starts automatically.
However, if the burst setting is improper, burst oscillation will not start. ([Conflict!] is displayed in
the top right part of the screen.) When the [?] soft key appearing at the left end is pressed, a message
about the inappropriate setting is displayed. Once the setting has been changed to an appropriate
setting, burst oscillation starts.
g) Stoppingautoburst→Notpossible
Oscillation cannot be stopped in the auto burst mode as is.
To stop oscillation, set [BrstMode] (burst mode) on the 2nd page of the setting screen to a setting
other than [Auto] (auto), and then set so that no trigger or gate signal is input.
p.115
To set continuous oscillation, change [Mode] (oscillation mode) to [Continuous].
h) Tooutputburstsyncsignal:Syncoutputsetting
Set burst sync signal with [SyncOut] (sync output) on the 2nd page of the setting screen. One of the
following two settings can be selected.
• Signal synchronized with the reference phase of the waveform [Sync]
• Signal synchronized with burst oscillation [BrstSync]
When[Sync]isselected
A TTL level signal that rises at the reference phase of the waveform is output from the sync/sub-
output terminal.
When[BrstSync]isselected
A TTL level signal synchronized with the burst oscillation is output from the sync/sub-output
terminal. As shown in the following figure, this signal is low during oscillation and high during
oscillation stop.
When the signal during burst is observed with an oscilloscope, it can be used as the trigger signal
for the oscilloscope.

Oscillation Stop
i) Usage of stop level
The level when oscillation is stopped is normally set with the oscillation start/stop phase, but it can
also be set independently from that with a proportion of the amplitude full scale.
Set [StpLvl] (stop level) on the 2nd page of the setting screen to [On] and set the level with a % value.
