To Set FSK Waveform
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 Output Frequency which shifts from the carrier frequency to 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 [Ext Trig/FSK/Burst] connector on the rear panel.
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.
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.
Carrier Waveform used in FSK can be set through the Sine, Square, Ramp, Arb button
on the front panel.
