Calibration Measurements
Before measuring the reflection factor of a device under test (DUT), it is
important to take calibration measurements as described in “Calibrating
the Return Loss Module” on page 176. These calibrations eliminate
wavelength dependencies, coupler directivity, insertion losses,
backscattering and other non-ideal characteristics of the system.
