OH4VNA-Optical Head for Vector Network Analyzers

OH4VNA is a bi-directional radiofrequency (RF-) over-fiber link that offers the most reliable means to measure the S11 of electrically small antennas in the 500 MHz – 6 GHz frequency range. The fiber optic system is used to replace the traditional coaxial cable to eliminate the influence of the cable connected to the antenna and improve the measurement accuracy.
