ABSTRACT:
A test circuit for use in testing amplifiers in order to check that they are functioning properly at operational power levels. The test circuit includes switching mechanisms which configure the amplifier in feedback mode in order to cause the amplifier to oscillate and a circuitry for measuring the power output of the amplifier during oscillation in order to thereby check that it is properly operational. The circuit may also include a load acting as a fixed attenuator for dissipating the power output of the amplifier and a bandpass filter for selecting an appropriate frequency of oscillation for the amplifier. The circuit may also include a control loop for regulating the amount of feedback and controlling the output power level.
