摘要

The Invention employs a method "feed-forward" to cancel High Power signals reflected and transmitted by a device which is desired before these Electrical parametersSignals from the Measuring Instrument.In the Measurement System for Devices of a Port, The Signal power is divided into two branches: One That Feeds directly into the device and another to cancel the reflected Signal.The Phase and magnitude of the signal cancellation is achieved by a device whose Transmission can be controlled.Simultaneously, the device is supplied with a low Signal Power necessary for determination of Electrical parameters, and from the Measuring Instrument.This Signal low power is not affected by the signal of high power thanks to the cancellation.The circuit is used to measure the transmitted Power in multi Port devices.
