Abstract :
AMiBA is a 3 mm wavelength astronomical interferometer consisting of 0.6 m to 1.2 m antennae. An artificial source is required for its calibration. We present an approach of using a tunable CW source to calibrate the phase and amplitude response. Performance and problems of the system are discussed.
