Two loops are provided for the testing of the R.F. amplifier one through variable fore and aft ganged attenuators and the amplifiers to one side of a ratio or difference meter and another loop through the attenuators, an isolator and another side of the ratio meter. This is accomplished alternately by a pair of switching devices and a coupler. In this way the meter reading will not be subjected to any errors presented by the attenuators. Author
