2.9.6 ASK
When using ASK (Amplitude Shift Keying), the carrier frequency and key
frequency will need to be set. The key frequency is the shift rate of modulated
waveform amplitude.
Press Mod → Type → ASK, the parameters of ASK modulation are shown in
Figure 2-29.

Explanation
Type
ASK
Amplitude shift keying modulation.
Source
Internal
The source is internal.
External
The source is external. Use the [Aux In/Out] connector at
the rear panel.
Key Freq
Set the frequency at which the output amplitude shifts
between the carrier amplitude and zero (internal
modulation only): 1mHz~1MHz.
Note:
The methods for setting the parameters of ASK are similar to AM. In addition,
the external modulating signal of ASK must be Square which complies with the
CMOS level specification.
