Modulating Waveform Source; Modulating Waveform Frequency - Hantek HDG2000B Series User Manual

5.4.4 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 Phase
Deviation is controlled by the ±2.5 V 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.

5.4.5 Modulating Waveform Frequency

When internal modulation source is selected, press Frequency to set the modulating waveform
frequency.
 Input the desired frequency value using the numeric keyboard or direction keys and knob.
 The modulating waveform frequency ranges from 2mHz to 50kHz, and the default value is
100Hz.
Note: This menu will be grayed out and disabled when other modulation sources except the
internal modulation source are selected.
