Functional Description (contd.)
FSK
The FSK Modulation is a modulation method, the output frequency of which
switches between two the pre-set frequencies (carrier waveform frequency
and the hop frequency). The frequency at which the output frequency
switches is called the key frequency. The key freq is determined by the
internal frequency generator or the signal voltage level offered by the Ext
Trig/Gate/Fsk/Burst connector in the rear panel:
