Function Waveform Generator Mode
Setting the Amplitude
The amplitude can be set in steps of 1 mV within the range 0.050 V – 5.000 V
(P-P value). using the numeric keys or the general purpose knob. Figure 3 -201
shows a sine waveform whose amplitude has been set to 5V.
Figure 3 201: Setting the Amplitude
Setting the Offset
The offset for each waveform can be set in steps of 5 mV within the range
2.5 V using the numeric keys or the general purpose knob. Figure 3 -202 shows
the waveform used in Figure 3 -201 after an offset of 1 V has been applied. The
dotted line in the figure indicates the zero line.

Setting the Polarity
This menu item sets the output waveform polarity. Each time the Polarity button
in the side menu is pressed, the polarity toggles between Normal and Invert and
the polarity of the displayed waveform is reversed. See Figure 3 -203. The figure
below at left shows a sine wave whose polarity has been set to "Normal," the
figure on the right shows a sine wave whose polarity has been set to "Invert."
