4. BASIC OPERATION
4.4.10 Setting the waveform polarity and amplitude range
a) Setting method
1.
Select the polarity/amplitude range
icon to the right of the waveform
name to display the current polarity/
amplitude range settings under that
icon.
Press the
ENTER
ENTER key to open
the polarity/amplitude range choice
list.
2.
Select the desired polarity and
amplitude range from the choice list
and then press the
ENTER
ENTER
key to set the input values and reflect
them to the output.
Alternatively, input the numbers
corresponding to the desired polarity
and amplitude range displayed in the
choice list from the numeric keypad to
set these values and reflect them to
the output.
b) What are the polarity and amplitude range?
The polarity can be inverted and the amplitude range can be changed to a single polarity for each
waveform. Examples for a sine wave are shown below.
Polarity
Amplitude Range
-
FS/0 ±FS 0/+FS
Normal
[Norm]
0
-FS
0
-FS
+FS
0
+FS

0
+FS
In the case of polarity inversion, only the waveform is inverted, and the DC offset sign of the output
remains unchanged.
Check
The polarity and amplitude range settings are done independently for each waveform.
Select the
polarity/amplitude
range icon and
then press the
ENTER key.
The current
polarity/amplitude
range is displayed
when the polarity/
amplitude range
icon is selected.
