Hantek HDG2000B Series - AM Modulation; Select am Modulation; Carrier Waveform Shape; Carrier Frequency

User Manual 32
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
Frequency Range
Sine
1μHz to 100MHz
Square
1μHz to 30MHz
Ramp
1μHz to 4MHz
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.
5.1.4 Modulating Waveform Source
HDG2000B can receive modulating waveform from Internal (default), External, or Other Channel.
Press Mod -> Source to select the modulation source.
