4.2 Sweep
WF1946B 4-21
• 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.
The trigger rate is common for CH1 and CH2.

• START-STATE and STOP-STATE : Set output to start and stop values, respectively.
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.
START-STATE is the same as pressing the
STOP
key
(during a single sweep).

synchronization output,

and Z-MARKER/SYNC/X-DRIVE output)”, cf.
• Sweep type set to duty : Output waveform fixed to squarewave (variable duty) and
waveform (Function) cannot be selected.
During a sweep, multiple pulses may be output in one cycle,
as shown below.
