4.2 Sweep

• Internal trigger source
:
Trigger signal of 50% duty is generated at the following trigger rate for sweep.
Even is set to less than 100 ms, the trigger is applied only at 100 ms intervals.
The trigger rate is common for CH1 and CH2.

• START-STATE and STOP-STATE : Set output to start and stop values, respectively.
Both START-STATE and STOP-STATE oscillation can be
conducted together with a gated sweep. Since sweep
synchronization output becomes the respective start and stop
states, full-scale adjustment of the recorder and the status of
external equipment can be checked.
“4.2 Sweep (

Sweep value and marker/sync/
X-DRIVE output)”, cf.
• If the sweep type (TYPE) is set to DUTY, the output waveform automatically becomes a squarewave
(variable duty). This makes it impossible to select the waveform (FUNCTION).
Multiple pulses may be output in one cycle during sweep, as shown below.
• If the frequency is low and the sweep rest period short, in some cases, oscillation may not stop
immediately at the end of sweep.
• During sweep, if the oscillation mode of the other channel is changed, sweep stops.
• To manually operate sweep (start, stop, pause, restart) for both channels simultaneously or to
operate sweep via remote control (GPIB or USB), set both channels to sweep mode and set
OPER-COMMON to on.
