Binary Phase Shift Keying (Bpsk) - UNI-T UTG2122B User Manual

3.1.7 Binary Phase Shift Keying (BPSK)

The function/arbitrary waveform generator can move between two preset phases (carrier phase and
modulation phase) in binary phase shift keying, expressing 0 and 1. Phase of carrier signal or modulation
signal is output according to logic of modulation signal. The modulation mode of the two channels is
mutually independent. You can configure same or different modulation mode for channel 1 and 2.
Select BPSK modulation
Press Menu → Mod → Type → BPSK successively to use BPSK function (if Type is not highlighted,
press soft key Type to select). After BPSK function is enabled, UTG2000B function/arbitrary waveform
generator will output modulated waveform with the current carrier phase (0˚ by default and unadjustable)
and modulation phase.
Select carrier waveform
BPSK carrier waveform can be sine wave, square wave, ramp wave or arbitrary wave (except DC), and is
sine wave by default. After PSK modulation is selected, press Carrier Parameter to select carrier waveform.
