Phase Noise Test System: N5511A Datasheet

Source: Keysight Technologies

The N5511A Phase Noise Test System is a replacement for the “gold-standard” Keysight E5500 phase noise measurement system that can measure phase noise down to kT (-177 dBm/Hz at room temperature). This thermal phase noise floor is the theoretical limit for any measurement. Therefore, the PNTS can measure at the limits of physics. Phase noise is unwanted phase modulation noise that emerges from nearly all radio frequency (RF) and microwave devices including oscillators, mixers, frequency dividers, frequency multipliers and amplifiers. PNTS is designed for phase noise “power users” whose needs are consistently unmet by existing commercial phase noise test instrumentation such as “one-box” integrated test solutions.
