Amplitude Shift Keying (ASK)

When using ASK (Amplitude Shift Keying), you can configure the generator to “shift”

its output amplitude between two preset amplitude values (“carrier amplitude” and

“modulating amplitude”).

To Select ASK Modulation


Press ModTypeASK to enable ASK function. When Mod is enabled, Sweep
or Burst will be disabled automatically (if enabled currently).

To Select Carrier Waveform Shape

PM carrier waveform could be Sine, Square, Ramp or Arbitrary waveform (except

DC). The default is Sine.
 Press the front panel key Sine, Square, Ramp or Arb (you need to press

Select Wform in the arbitrary waveform setting interface to select the desired

arbitrary waveform) to select the desired carrier waveform shape.

 Pulse, Noise and DC could not be used as carrier waveform.

To Set Carrier Waveform Parameters

The different settings of various parameters (frequency, amplitude, DC offset and

etc.) of the carrier waveform will influence the ASK modulated waveform. For

different carrier waveform shape, the ranges of the various parameters are different

(the ranges are related to the model of the instrument used and the carrier

waveform currently selected. See Specifications for details). For all carrier

waveform shapes, the default values are 1kHz frequency, 5Vpp amplitude and 0V

DC

offset.


 When the carrier waveform currently selected is Sine, Square or Ramp, please

refer to the introduction in To Output Basic Waveform to set the

parameters of the carrier waveform currently selected.

 When the carrier waveform currently selected is arbitrary waveform, please

refer to the introduction in To Output Arbitrary Waveform to set the

parameters of the carrier waveform currently selected.
