Press Parameter→Frequencysoftkey, then enter required numerical value, and select unit.
Modulation Source Selection
UTG1000A function/arbitrary waveform generator can select internal modulation source or external modulation
source. After enabling PSK function, the default of modulation source is internal. If need to change, press
Parameter→Modulation→Source→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 PSK rate can be set to customize the moving frequency between carrier wave phase and modulation phase.
2) External Source
When modulation source is external, carrier waveform will be modulated by an external waveform. Carrier wave
phase will be output when external input logic is low, and modulation phase will be output when external input
logic is high.
PSK Rate Setting
When modulation source is internal, the moving frequency between carrier wave phase and modulation phase can
be set. After enabling PSK function, PSK rate can be set and the settable range is 2mHz to 100kHz, the default rate is
100Hz. If need to change, press Carrier Wave Parameter→Rate in turn.
Modulation Phase Setting
Modulation phase indicates the change between the phase of PSK modulated waveform and the phase of carrier
wave phase. Settable range of PSK phase is from 0º to 360º, and the default value is 0º. If need to change, press
Parameter→Phase in turn.
