To Set Modulate/Sweep/Burst
As shown in the following figure, there are three buttons on the front panel, which are
used for Modulation, Sweep and Burst settings. The instructions below will help you to
be familiar with the settings of these functions.

Modulate/ Sweep/ Burst button
NOTE: Mod, Sweep and Burst functions are only used for CH1.
1. Press the Mod button, and a Modulated waveforms will be generated.
Parameters are set by using the menu buttons. The modulated waveform can be
changed by changing the parameters such as Type, Internal/external Modulation,
Depth, Frequency, Waveform, etc.
DG1022 can modulate waveform using AM, FM, PM and FSK. Sine, Square, Ramp
or Arbitrary waveforms can be modulated (Pulse, Noise and DC cannot be
modulated).

2. Press the Sweep button, Sine, Square, Ramp or Arbitrary waveform can be swept
(Pulse, Noise and DC can not be swept).
In the Sweep Mode, DG1022 generate signal with variable frequencies.
