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
When the Shift key is illuminated, press Home/Menu Modulation "ASK" to
enable the ASK function. When Modulation is enabled, Sweep or Burst will be
automatically disabled (if enabled currently). Tap the icon
at the upper-right
corner of the interface (when Sine is selected as the carrier waveform) to view and
set the parameters of the current carrier waveform. Tap the icon
at the
upper-right corner of the interface again to go back to the current modulation
parameter interface.
To Select the Carrier Waveform
ASK carrier waveform could be Sine, Square, Ramp, or Arbitrary waveform. The
default is Sine.
When the Shift key is illuminated, press Home/Menu Continuous to
select the desired carrier waveform. Also, when the Shift key is not illuminated,
you can directly press the corresponding waveform function key on the front
panel to select the desired carrier waveform.
Pulse, Noise, Harmonic, Dual-tone, and DC could not be used as carrier
waveform.
To Set Carrier Waveform Parameters
The different settings of various parameters (e.g. frequency, amplitude, offset, and
start phase) of the carrier waveform will affect the output ASK modulated waveform.
For different carrier waveform shapes, the ranges of the various parameters are
different (the ranges are related to the instrument model that you are using and the
currently selected carrier waveform). For all carrier waveform shapes, the default
values are 1 kHz frequency, 5 Vpp amplitude, 0 Vdc offset, and 0° start phase.
When the carrier waveform currently selected is Sine, Square, or Ramp, please
refer to descriptions 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 descriptions in "To Output the Arbitrary Waveform" to set the
parameters of the carrier waveform currently selected.
