• FUNCTION determines the sweep type.
: For example, provides step-type change of output (e.g., frequency) at the sweep time halfway
point. LIN/LOG provides linear or logarithmic variation of the output with respect to the time axis.

• Internal sweep trigger source
: The trigger signal is generated at the following rate, then sweep is conducted.
However, the trigger interval is 100 ms even if set to less.

• START-STATE and STOP-STATE : Respectively set the output to start and stop values.
Since the sweep auxiliary output becomes the respective start
and stop states, the full scale of the recorder can be adjusted
and the state of external equipment can be checked. The
Start-State is the same as pressing the
STOP
key (during single sweep).

•
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.
• To generate the trigger signal via remote control (GPIB or USB), set the TRG command from the
remote control interface.
For details of the remote control command,
