4. At this time, the RF interface of the SSG3000X outputs an IQ modulation signal with a
modulation mode of 32QAM, and the IQ modulation signal is connected to an IQ
demodulation device to observe the demodulation characteristics of the IQ
modulation signal;
Note: IQ compensation can be performed through theI/Q adjustment menu of the
SDG6000X. For example, when the IQ modulation signal shows a significant local
oscillator leakage, it can be solved by alternately adjusting the Offset of I and Q.
