Latest Patents

Ning Cheng holds a patent for "Automatic fixture removal using one-port measurement." This invention involves measuring the scattering parameters of a test fixture with a first port and a second port. The process includes outputting a one-port reflection test signal from a test instrument to the first port, while the second port is terminated in a reflective termination with a known reflection coefficient. The test instrument receives a one-port reflection measurement signal from the first port. The signal is then subjected to first and second time gating to generate time-gated measurement signals, which are used to derive the scattering parameters.
