3.1.14 QAM (Quadrature Amplitude Modulation) 

In quadrature amplitude modulation mode, set two signals of the same frequency but with phase 
difference 90°(usually represented by Sin and Cos)as the carrier wave, modulating the carrier 
wave by baseband signal. UTG9000T function/arbitrary waveform generator can output seven 
modulation types: QAM4, QAM8, QAM16, QAM32, QAM64, QAM128 and QAM256M. The 
modulation modes for each channel are independent, it can set the same or different modulation 
modes to each channel. 
 
Note: It is recommened to use the 10MHz reference output signal of this instrument as the input 
reference clock of the demodulation instrument or input the demodulation instrument reference 
clock as the signal clock, Accurate the signal demodulation and eliminate the phase deviation by 
clock sync.
