4.2 Sweep
WF1966
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
: Trigger signal of 50% duty is generated at the following trigger rate for sweep.
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).
Relationship between sweep values and sweep synchronization
output,

Sweep value and
marker/sync/ X-DRIVE output)”, cf.
• If the sweep type (TYPE) is set to DUTY,
the output waveform is forced to become a square wave
(variable duty), making it impossible to select the waveform (FUNCTION).
Multiple pulses may be output in one period during sweep, as shown below.
•
During sweep, if the oscillation mode of the other channel is changed, sweep stops.
