Press Parameter→Frequency softkey, then enter required numerical value, and select unit.
Modulation Source Selection
The device can select internal modulation source or external modulation source. After enabling FSK
function, the default of modulation source is internal. If need to change, press
Parameter→ModulationSource→External in turn.
1) Internal Source
When modulation source is internal, internal modulation wave is a square of 50% duty cycle (not
adjustable). The FSK rate can be set to customize the moving frequency between carrier wave
frequency and hop frequency.
2) External Source
When modulation source is external, carrier waveform will be modulated by an external waveform. FSK
output frequency is determined by the logic level of modulation interface on front panel. For example,
output the carrier wave frequency when external output logic is low, and output hop frequency when
external input logic is high.
