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 Mod Type ASK 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.
