Am Modulation; Select Am Modulation; Carrier Waveform Shape; Carrier Frequency - Hantek HDG2000B Series User Manual

5.1 AM Modulation

A modulated waveform consists of a carrier waveform and a modulating waveform. In AM, the
carrier amplitude is varied by the voltage level of the modulating waveform.

5.1.1 Select AM Modulation

Press Mod->Type->AM to enable AM function.
 When Mod is enabled, Sweep or Burst will be disabled automatically.
 After AM is enabled, the instrument will generate AM waveform with the currently specified
carrier and modulating waveforms. To avoid multiple waveform changes, enable modulation
after configuring the other modulation parameters.

5.1.2 Carrier Waveform Shape

AM 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.

5.1.3 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.

5.1.4 Modulating Waveform Source

HDG2000B can receive modulating waveform from Internal (default), External, or Other Channel.
Press Mod -> Source to select the modulation source.
