To output an ASK waveform
(AFG1062 only)
Amplitude Shift Keying modulation is a modulation technique that shifts the output signal amplitude
between two amplitudes: the carrier amplitude and modulating amplitude.
1.
Select a waveform and
then push the front-panel
Mod button.
In this example, use
the
sine waveform as an
output waveform (carrier
waveform).
2.
Press Mod.
NOTE: You can only choose
sine, square, ramp, or arb as
a carrier waveform.
3.
Press Type to display the
modulation selection menu.
Press NextPage.
4.
Select ASK as the
modulation type.
5.
The ASK parameter setting
screen is displayed. Select
Internal or External as ASK
source.
6.
If you select Internal, you can
set the ASK Rate. The rate at
which the output amplitude shifts
between the carrier amplitude
and the modulating amplitude is
called the ASK rate.
If you select External, press Slope
to switch between Positive and
Negative. The external source can
be offered by the Fsk/Ext Trig In
connector in the rear panel. Set the
Slope to Positive and the
generator would output the lower
of the carrier amplitude and
modulating amplitude when the
external input signal is logic low
level and output the greater when
the external input signal is logic
high level. The situation is the
opposite when the Slope is set to
Negative.
7.
Set Amplitude.
Carrier waveform amplitude
shifts to the modulating
amplitude with the specified ASK
rate, and then returns to the
original amplitude.
