FSK
The FSK Modulation is a modulation method, the output frequency shifts between the
two pre-set frequencies (Carrier Waveform Frequency and the Hop Frequency). The
Frequency for the Output Frequency to shift from the carrier waveform frequency to
and from the Hop frequency is called the FSK rate. The frequency by which the output
frequency shift from each other is determined by the Internal Frequency generator or
the Signal Voltage Level offered by the [Ext Trig/FSk/Burst] connector in the rear
panel:
z
If you choose the Internal Modulation, the frequency at which the output
frequency shifts between the carrier frequency and the Hop frequency is
determined by the set FSK rate.
z
If you choose External Modulation and overlook the FSK rate, the output frequency
is determined by the Voltage Level of the [Ext Trig/FSk/Burst] connector on the
rear panel. If the Voltage Level is low, then generate the carrier frequency; when
the voltage level is High, generate the Hop frequency.
