2.8 I/Q Modulation
I/Q modulation, i.e. two orthogonal signals (carriers with the same frequency,
phase difference of 90°, generally expressed by Sin and Cos) and I (In-Phase,
in-phase component) and Q (Quadrature Phase) signals are respectively
modulated by carrier and transmitted together, thereby improving spectrum
utilization.
Note: Only some models are equipped with IQ modulation function. For specific
models, please refer to the SSG5000X data sheet.
