An automated phase noise test measurement system includes a software controlled phase shifter to maintain quadrature so that a carrier may be removed from a signal provided by UUT. In this fashion, the UUT' s phase noise may be measured. Based upon the UUT' s measured phase noise, controllable variable(s) within the UUT are tuned so as to minimize the measured phase noise.
L'invention concerne un système de mesure d'essai à phase de bruit automatisé comprenant un compensateur de phase commandé par logiciel afin de maintenir la quadrature de sorte qu'une porte puisse être éliminée d'un signal généré par UUT. Ainsi, le bruit de phase de l'UUT peut être mesuré. Sur la base du bruit de phase mesuré, la/les variables régulables dans l'UUT sont syntonisées de manière à minimiser le bruit de phase mesuré.
