After the carrier waveform is selected, you can press Freq/Period to highlight
"Freq", and then use the numeric keyboard or direction keys and knob to input the
desired frequency value.
To Select the Modulating Waveform Source
DG4000 can receive modulating waveform from internal or external modulation
source. Press
Mod

Source to select "Int" or "Ext" modulation source.
1.
Internal Source
When internal modulation source is selected, press Shape to select Sine,
Square, Triangle, UpRamp, DnRamp, Noise or Arb as modulating waveform.
The default is Sine.

Square: 50% duty cycle.

Triangle: 50% symmetry.

UpRamp: 100% symmetry.

DnRamp: 0% symmetry.

Arb: when arbitrary waveform is selected as modulating waveform, the
generator would limit the waveform length to 2kpts automatically.
Note: Noise can be used as modulating waveform but cannot be used as
carrier waveform.
2.
External Source
When external modulation source is selected, the
Shape menu will be grayed
out and disabled. The generator receives the external modulating signal from
the
[Mod/FSK/Trig] (as shown in the figure below) connector at the rear
panel. The phase deviation is controlled by the ±2.5 V signal level of the
connector.
