摘要： A noise measurement test system 10' for making phase noise and amplitude noise measurements of microwave signals derived from a continuous wave RF source. The system 10' comprises an RF input for receiving an applied RF noise signal and an RF coupler 11 coupled to the RF input for splitting the applied RF noise signal into first and second paths 18a, 18b. A mixer 15 that comprises a synchronous phase detector 15 is coupled to receive signals from the first and second paths 18a, 18b, respectively, and which outputs demodulated phase noise. The first path 18a comprises a variable attenuator 14 and a variable phase shifter 13 coupled between the coupler 11 and the first input of the mixer 15 for providing a reference signal input to the synchronous detector 15. The second path 18b comprises a delay line and an adjustable RF carrier nulling circuit 30 coupled between the coupler 11 and the mixer 15. A video amplifier is coupled to an output of the mixer 15 for providing a baseband video output signal from the system 10' that is processed to produce noise data.

摘要： An RF amplifier arrangement for providing output signals having a controlled frequency distribution and wherein the amplitude and phase of the input signals to an RF amplifier are controlled as a function of the amplitude and phase, respectively, of the output signals from the RF amplifier and also the amplitude of the input signals are adjusted so as to cause the power of the output signal to vary in accordance with a predetermined sequence, whereby such amplitude control of the input signals results in a modified frequency distribution in the energy of the output signals.
