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

5.3.2 Carrier Waveform Shape

FM carrier shape: Sine (default), Square, Ramp, Pulse, Arbitrary (except DC) or Harmonic
waveform.
Press the front panel key Sine, Square, Ramp, Pulse, Arb -> Type or Harmonic to select a
desired carrier waveform shape.
Noise and DC could not be used as carrier waveform.

5.3.3 Carrier Frequency

The maximum carrier frequency varies by function for HDG2102B, as shown below. The default is
1 kHz for all functions.
Carrier Waveform
Sine
Square
Ramp
Pulse
Arbitrary Waveform
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.

5.3.4 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 frequency
deviation is controlled by the ±2.5 V signal level on the front-panel [Sync/Mod/Trig] connector.
