Carrier Wave Waveform Selection

PSK carrier waveform can be: Sine wave, square, ramp wave or arbitrary wave (except

DC), and the default is sine wave. Press Carrier soft key to enter carrier waveform

selection interface.

Carrier Wave Frequency Setting

Modulation Source Selection

UTG2000B 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 Param → Source → External in turn.

1)Internal Source

When modulation source is internal, internal modulation wave is a square wave of 50%

duty ratio (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.
