Modulation Frequency; Phase Deviation; Ask Modulation; Select Ask Modulation - Hantek HDG3000BC Series User Manual

Other Channels
CH1 and CH2 can be used as modulation sources reciprocally. When CH1 is used as the
modulated wave, CH2 can be used as the modulation source. And vice versa.
When selecting another channel as the modulation source, please turn on the output of that
channel.

5.4.5 Modulation Frequency

When internal modulation source is selected, press [Mod] >Frequency softkey to set the
frequency of the modulating waveform.
 Use the numeric keypad or direction keys and knob to enter the desired frequency values.
 The modulating waveform frequency range is 2mHz to 1MHz, and the default value is 100Hz.
Note: This menu will be grayed out and disabled when other modulation sources except the
internal modulation source are selected.

5.4.6 Phase Deviation

Phase deviation is the deviation of the modulating waveform phase relative to the carrier
waveform phase. Press [Mod] > Deviation softkey to set the PM phase deviation.
 Use the numeric keypad or direction keys and knob to input the desired phase values.
 The phase deviation is set to 0 ° to 360 °.
When external modulation source is selected, the phase deviation is controlled by the ±4V signal
level on the [FSK/Trig/Sync/Extmod] connector on the rear panel.For example, if the phase
deviation is set to 180 °, +4V signal level corresponds to a 180º phase variation. The lower the
external signal level, the less deviation would be generated.

5.5 ASK Modulation

Users can configure the instrument to "shift" its output amplitude between two preset values using
ASK modulation. The rate at which the output shifts between the two amplitudes (called the
"carrier amplitude" and the "modulation amplitude") is determined by the internal signal level of
the instrument or the external signal level on the [FSK/Trig/Sync/Extmod] connector on the rear
panel.

5.5.1 Select ASK modulation

Press [Mod] >Type > ASKsoftkey to enable this function.
 When Mod is enabled, Sweep or Burst will be disabled automatically.
 After ASK is enabled, the instrument will generate ASK waveform with the currently specified
