Osk Modulation; Select Osk Modulation - Hantek HDG2000B Series User Manual

frequency depends on the carrier waveform currently selected.
Sine: 1μHz to 100MHz
Square: 1μHz to 30MHz
Ramp: 1μHz to 4MHz
Pluse: 1μHz to 15MHz
Arb: 1μHz to 20MHz
Press HopFreq1/HopFreq2/HopFreq3 to set the parameter. Use the numeric keyboard or
direction keys and knob to input the desired frequency value.

5.12 OSK Modulation

When OSK (Oscillation Shift Keying) modulation is selected, users can configure the generator to
output a sine signal with intermittent oscillation as shown in the figure below (the carrier waveform
is 100Hz and the OSK rate is 10kHz). The start-oscillation and stop-oscillation of the internal
crystal oscillator are controlled by the internal signal level or signal level at the [Mod/FSK/Trig]
connector at the frount panel. When the internal crystal oscillator starts to oscillate, the instrument
starts to output the carrier waveform and when the internal crystal stops oscillating, the output
stops.

5.12.1 Select OSK Modulation

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