4.4.9 Setting the output level with high level/low level
The output level can be set by specifying the high level and low level of the waveform,
instead of setting the amplitude and DC offset.
a) Changing the amplitude/DC offset display to high/low display
There are three methods for changing the amplitude/DC offset display to high/low display,
described below.
○
Changing to high/low display with the [High] or [Low] soft key
When the amplitude or DC offset input field is open and the current value is displayed,
the [High] or [Low] soft key is displayed. By pressing this key, the high level or low level
input field opens, and the item displays change from [Amptd] and [Offset] to [High] and
[Low], respectively.
The [High] or [Low] soft key changes to [Amptd] or [Offset]. When the [Amptd] or [Offset]
soft key is pressed at this time, the amplitude or DC offset input field opens.
○
Changing to high/low display by pressing the AMPTD key twice
While the amplitude input field is not opened, press the AMPTD shortcut key twice
to open the high level input field.
If the high level input field is open, the amplitude/DC offset display and high/low display
are toggled each time the
AMPTD key is pressed.
○
Changing to high/low display by pressing the OFFSET key twice
While the DC offset input field is not open, press the OFFSET shortcut key twice to
open the low level input field.
If the low level input field is open, the amplitude/DC offset display and high/low display
are toggled each time the
OFFSET key is pressed.
Once the high level or low level field is open, the setting procedure is the same as for DC
offset.
When a numeric value is input from the numeric keypad, the high level/low level setting
unit is displayed on a soft key.
The display changes as follows when the high level/low level display is switched to.

b) AC+DC limitation
The high level and low level are limited to the range of − 10 V to + 10 V/open.
The maximum range varies according to the output voltage range setting and the external
