Measurement
251
where the up/down conversion method is used, the power of the
LO signal is distributed to the calibration mixer and the
measured mixer through the power splitter. During a
characteristics evaluation of the calibration mixer, the LO power
level used by the drive of the calibration mixer must be equal to
the LO power level with the measured mixer connected. This is
because the mixer's conversion loss and reflection coefficient
are significantly affected by the power level of the LO signal.
