User Manual

Check the shape of BPSK modulation waveform through oscilloscope, which is shown in

the figure below:

h) Quadrature Phase Shift Keying(QPSK)

The function/arbitrary waveform generator can move between four preset phases (carrier

phase and 3 modulation phases). 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 QPSK modulation

Press Menu → Mod → Type → QPSK to enable QPSK function (if Type is not highlighted,

press soft key Type to select). After QPSK function is used, UTG2000B function/arbitrary

waveform generator will output modulated waveform with the current carrier phase and

modulation phase.
