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

5.12.2 Carrier Waveform Shape

OSK carrier waveform can only be sine waveform. Press Sine at the front panel.

5.12.3 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.
The range is from 1μHz to 100MHz. The default frequency is 1KHz.

5.12.4 Modulating Waveform Source

Press Mod -> Source to select Internal (default) or External as the modulation source.
Internal Source
When internal modulation source is selected, the modulating waveform is set as a Square with
50% duty cycle, and the intermittence time and oscillate time of the output signal is determined by
the OSK "Rate".
External Source
With the External source, the generator receives the external modulating signal from the
[Sync/Mod/Trig] connector at the front panel.

5.12.5 OSK Rate

When internal modulation source is selected, press Rate softkey to set the OSK frequency.
 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.
Note: This menu will be grayed out and disabled when the external modulation source are
selected.
