3.1.8 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.
Select carrier waveform
QPSK carrier waveform can be sine wave, square wave, saw tooth wave or arbitrary wave (except DC),
and is sine wave by default. After QPSK modulation is selected, press Carrier to select carrier waveform.
