® Set the Carrier Frequency
Please refer to the AM carrier waveform setting.
e Select the Modulation Source
The device can select internal or external modulation source. After enabling FSK function, the
default modulation source is internal. You can change it to external modulation source by
multi-functional knob or pressing |Source hd External).

1) Internal Source
When modulation source is internal, internal modulation wave is a square wave of 50% duty ratio
(not adjustable). The FSK rate can be set to customize the moving rate 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 external digital modulation interface
(INPUT/CNT interface). For example, output the carrier wave frequency when external output logic
is low, and output hop frerquency when external input logic is high.
