Signal purity determines the quality of measurements in several applications such as radar, transceiver, ADC/DAC, and components testing. Rubidium delivers phase noise performance with its low and ultra-low phase noise options. Coupled with harmonic and spurious performance, the Rubidium offers overall signal purity performance to make more accurate measurements. Rubidium offers atomic clock frequency stability with an internal rubidium frequency reference option and it’s an ideal signal generator for Metrology and high-speed clock applications.
