ASK
ASK is a form of modulation that represents digital data as variations in the
amplitude of a carrier wave. The amplitude of an analog carrier signal varies
in accordance with the bit stream (modulating signal), keeping frequency and
phase constant. The parameters for the ASK are as shown in Figure 2- 32

Explanation
Key Freq
Set the frequency at which the output
amplitude shifts between the carrier
amplitude and zero (internal modulation
only): 2mHz~50kHz.
Type
ASK
Amplitude shift keying modulation.
Source
Internal
The source is internal.
External
The source is external; Use the
[ExtTrig/Gate/FSK/Burst] connector in the
rear panel.
