• Internal trigger source
:
The internal trigger signal is produced at the rate indicated below. Even is set to
less than 100 ms, the trigger is applied only at 100 ms intervals.

• 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 adjustments of the recorder and the status of
external equipment can be checked.

•
Sweep type set to duty : Output waveform fixed to squarewave (variable duty) and waveform
(Function) cannot be selected.
During sweep, multiple pulses may be produced within 1 period output
as indicated in the figure.
• If the frequency is low and the sweep rest period short, in some cases, oscillation may not stop
immediately at the end of sweep.
• When an amplitude sweep is set with 0 as the start or stop values and the sweep function is set with
LOG / LOG / LOG , "SETTING CONFLICT 001" is displayed continuously during a
short trigger cycle and the menu may not be displayed. In such cases, switch the trigger source, or
stop input to the SWEEP PAUSE IN connector.
