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 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 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.

In the case of polarity inversion, only the waveform is inverted, and the DC offset sign of the
output remains unchanged.

then press the
ENTER key

The current
