Abstract: A source of radiation comprises a first low frequency oscillator 200 for providing a reference signal and a plurality of phase shifters 210a, 210b, 210c coupled to the first oscillator. In addition there are a plurality of phase locked loops 230a, 230b, 230c, each phase locked loop having a respective Voltage Controlled Oscillator (VCO) 240a, 240b, 240c for outputting a signal. Each phased locked loop is coupled to a respective one of the phase shifters, so that in use each VCO is phase locked to a reference signal which has been phase shifted by a respective one of the phase shifters. In this way the phase of the radiation output by each VCO may be controlled indirectly by controlling the phase shift of the reference signal. In a preferred embodiment the phase shifters are adjustable to shift the phase by an adjustable amount.

Abstract: A reference signal is split and input to first and second variable phase shifters 10, 20. The first and second variable phase shifters output to first and second inputs 31, 32 respectively of a phase comparator 30. Initially, the first and second variable phase shifters 10, 20 are preferably set to the same phase. The first and second phase shifters are then aligned, e.g. by adjusting the calibration of one or both of the phase shifters so that the phase comparator 30 indicates that they output the same phase. The phase of the first phase shifter 10 is then adjusted by one step and a phase delay section 60 is placed between the output of the second phase shifter 20 and the second input 32 of the phase comparator 30. The first and second phase shifters 10, 20 are then aligned again.
