Calibrating two 6-port reflectometers with one impedance standard helps you master a streamlined calibration process.
This nonfiction guide describes a technique for calibrating a pair of 6-port reflectometers to measure reflection coefficients and scattering parameters. The method connects the devices in a simple setup, uses two terminations and a standard, and yields a closed-form solution without iteration.
The described operations focus on practical steps: linking the two 6-ports, configuring a calibration circuit with unknown impedance terminations and a leveling loop, and then incorporating a known standard. The standard can be a single termination with known impedance or a precise length of transmission line with known characteristics. The approach emphasizes ease of use and reliability across frequencies.
