Press Parameter→Frequency softkey, then enter required number value, and select unit.
Modulation Source Selection
The device can select internal modulation source or external modulation source. After enabling ASK
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 wave of 50% duty cycle (not
adjustable). The ASK rate can be set to customize modulated waveform amplitude hopping frequency.
2) External Source
When modulation source is external, carrier waveform will be modulated by an external waveform. ASK
output amplitude is determined by the logic level of modulation interface on front panel. For example,
output the carrier wave amplitude of current setting when external input logic is low, and output
carrier wave amplitude less than the amplitude of current setting when external input logic is high.
