FSK
The FSK Modulation is a modulation method, the output frequency of which switches
between the two pre-set frequencies (Carrier Waveform Frequency and the Hop
Frequency). The Frequency for the Output Frequency to switch from the carrier
waveform frequency to and from the Hop frequency is called the FSK rate. The
frequency by which the output frequency switch from each other is determined by the
Internal Frequency generator or the Signal Voltage Level offered by the [Trig In]
connector on the rear panel:
z
If you choose the Internal Modulation, the frequency at which the output
frequency shift 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 [Trig In] 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.
