Carrier Waveform Shape; Carrier Frequency; Modulating Waveform Source; 4Fsk Rate - Hantek HDG2000B Series User Manual

 When Mod is enabled, Sweep or Burst will be disabled automatically.
 After 4FSK is enabled, the instrument will generate 4FSK waveform with the currently specified
carrier and modulating waveforms. To avoid multiple waveform changes, enable modulation
after configuring the other modulation parameters.

5.11.2 Carrier Waveform Shape

4FSK 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.

5.11.3 Carrier Frequency

Choose carrier waveform shape, press Frequency/Period to highlight "Frequency", and then use
the numeric keyboard or direction keys and knob to input the desired frequency.
Different carrier waveforms have different frequency ranges as shown in the table below. For all
the carrier waveforms, the default value is 1KHz.

5.11.4 Modulating Waveform Source

4FSK uses internal modulation source. The modulation waveform is square.

5.11.5 4FSK Rate

4FSK uses internal modulation source.The 4FSK Rate is the rate at which the output frequency
shifts between "carrier frequency" and three "modulating frequencies". Press Rate to set.
 Use the numeric keyboard or direction keys and knob to input the desired frequency value.
 The frequency range is from 2mHz to 1MHz and the default is 100Hz.

5.11.6 Hopping Frequency

Alternating frequency (hopping frequency) is the modulating frequency. The range of hop
