4.8.7 Setting DC offset sweep
For the manipulation methods that are common with the sweep setting screen, refer to p.87 and
p.90 .
a) DC offset sweep example
The following is an example of continuous, linear shuttle sweep.
Shuttle sweep
Sweep value
Output signal
Start value
Stop value
Sweep time Sweep time
b) Selecting DC offset sweep
When [Mode] (oscillation mode) is set
to [Sweep] (sweep), set [Type] (sweep
type) on the 2nd page of the setting
screen to [Offset] (DC offset).
c) Waveforms for which DC offset sweep is not possible
None. DC offset sweep is possible for all waveforms. However, when DC is selected as the waveform,
the DC level itself becomes the sweep object. Moreover, when DC is selected as the waveform, gated
single-shot sweep cannot be done.
d) Setting items required for DC offset sweep
Set the following items on the 2nd page of the setting screen. The DC offset settings on the 1st page
of the setting screen are invalid.
• Start DC offset [Start]
• Stop DC offset [Stop]
• Sweep time [Time]
This is the transition time from start DC offset to stop DC offset.

p.91
• Sweep mode [SwpMode]
Continuous, single-shot, and gated single-shot can be chosen from.

p.91
• Sweep function [SwpFctn]
One-way/shuttle can be chosen from.

p.90
Setting with [Center] (center DC offset) and [Span] (span DC offset) instead of start DC offset and
stop DC offset is also possible.

p.90
When the sweep mode is single-shot or gated single-shot, [Trig] (trigger condition) must be set..

p.94
Select [Offset] in
[Type] and then
press the ENTER
key.
