WILCOM T207 Longitudinal Balance Test Set

The Model T207 Longitudinal Balance Test Set is designed to measure the longitudinal balance of single-port or two-port circuits and devices. This test set permits evaluation of relays, feed coils, networks, long-line units, amplifiers and other equipment present on the typical communications circuit. These devices may have poor longitudinal balance and thus
contribute to the susceptibleness of the facility. The measuring technique and circuit configuration conforms to the IEEE standard 455-1976 for Longitudinal Balance Measurements.
