The parameters that can be set for ASK are listed in the table below.
Table 10-9 ASK parameter descriptions
ASK
Keying frequency
The rate of the binary sequence. This value can be set directly when
the source = internal and the internal source is a clock sequence with
the specified frequency multiplied by 2. When the source = external, the
amplitude of the carrier is determined by the 0/1 state of the external
trigger input
FSK
FSK is frequency keying, here refers to binary frequency keying. The frequency of the modulated
carrier varies with the 1/0 state of the binary sequence, i.e. a carrier frequency of f
0
means that
0 is transmitted and a carrier frequency of f
1
means that 1 is transmitted.
The parameters that can be set for FSK are listed in the table below.
Table 10-10 FSK parameter descriptions
FSK
Keying frequency
Same as ASK
Frequency
hopping frequency
The frequency representing 1, i.e.f
1
. The frequency representing 0 (i.e.f
0
)
is the currently set carrier frequency
PSK
PSK is phase keying, here refers to binary phase keying. The instantaneous phase of the carrier
being modulated varies with the 1/0 state of the binary sequence.
The parameters that can be set for PSK are listed in the table below.
