User Manual 35
Pulse
1μHz to 15MHz
Arbitrary Waveform
1μHz to 20MHz
After the carrier waveform is selected, you can press Frequency/Period to highlight "Frequency",
and then use the numeric keyboard or direction keys and knob to input the desired frequency
value.
5.2.4 Modulating Waveform Source
HDG2000B can receive modulating waveform from Internal (default), External, or Other Channel.
Press Mod -> Source to select the modulation source.
Internal Source
When internal modulation source is selected, press Shape to select Sine, Square, Ramp, Noise
or Arb as modulating waveform. The default is Sine.

Sine waveform

Square: 50% duty cycle

Ramp: 50% symmetry.
Note: Noise can be used as modulating waveform but cannot be used as carrier waveform.
External Source
With the External source, an external waveform modulates the carrier waveform. The modulation
amplitude (DSB-AM) is controlled by the ±2.5V signal level on the front-panel [Sync/Mod/Trig]
connector.
Other Channel
Other channel: CH1 and CH2 can be used as modulation sources reciprocally. When CH1 is used
as the modulated wave, CH2 can be used as the modulation source. And vice versa.
