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
AMPTD key twice
While the amplitude input field is not opened, press the
AMPTD
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
AMPTD key is pressed.
Changing to high/low display by pressing the
OFFSET
OFFSET key twice
While the DC offset input field is not open, press the
OFFSET
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
OFFSET key is pressed.
High level input field Low level input field
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.
Item name: Amptd → High, Offset → Low
Unit display: Vp-p, Vpk, Vrms, dBV, dBm, V → V
Soft key: High → Amptd, Low → Offset
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 addition
input setting.
