SUM (Sum Modulation)
The modulated waveform consists of the carrier wave and the modulating wave. For
SUM, the amplitude of the carrier wave varies with the instantaneous voltage of the
modulating wave. The SUM user interface is shown below.

How to set the parameters of SUM
(1) Press the Mod function key, then press the Type softkey, turn the rotary control
to select SUM, press the OK softkey.
(2) Select carrier wave shape:
The carrier wave can be Sine, Square, or Ramp. Press , , or to
select a desired carrier wave shap.
(3) Set carrier wave parameters:
Press the wave shap key of the selected carrier wave to display the waveform
and parameters of the carrier wave. You can change the parameters of the
carrier wave. Press Mod to return to the modulation mode interface.
(4) Select modulating wave source:
Press the Source softkey to select the modulating wave source.
If you select External, use the Mod/FSK/Trig connector at the rear panel to
input the external modulating signal, the SUM setting is completed.
If you select Internal, continue with the following steps.
(5) Select modulating wave shape:
Press the Shape softkey, then press the Sine, Square, Ramp, Noise, or Arb
softkey to select the modulating wave.
