Rigol DG4000 Series Instruction Manual

Synchronizing Outputs with a Rigol DG4000 Series Arbitrary Waveform Generator
The Rigol DG4000 series of arbitrary waveform generators can be used to create and source many different types of waveforms.
They feature sine, square, ramp, and pulse waveforms as well as the ability to create arbitrary waveforms. This can be useful when
testing the limitations or to ensure normal operation of a design.
In some instances, you may need to synchronize both outputs of the DG4000. In this application note, we are going to describe how
to use the coupling and DDS Hold features of the DG4000 series to synchronize the outputs. This will link each channel together.
The amplitudes and phases of each channel will change simultaneously.
Initial Setup
First, we'll start at factory default settings to make configuration steps repeatable. You can reset the factory defaults by pressing
the green Preset Key on the front panel.
Alternately, you can set the PowerOn selection to Default by pressing Utility > System > PowerOn = Default and then power cycle
the instrument.
Now that the instrument is in factory defaults, we can begin to configure the instrument for channel synchronization.
Using Channel Copy
Channel copy enables you to copy the characteristics of one channel of the generator and apply those settings to the other channel.
In this example, we are going to configure a square wave with a total period of 15ms and then set the duty cycle to a minimum to
create a short pulse.
