Abstract: |
Based on the digital oscilloscope and vector network analyzer, two methods of the amplitude and phase error measuring of wide band quadrature demodulator are proposed and compared. They've also been verified in the measurement of a quadrature demodulator of 100MHz band. |
Keywords: wide band quadrature demodulator digital oscilloscope vector network analyzer |
