Phase Noise Test System
N5511A - Keysight Technologies
The Keysight N5511A phase noise test system (PNTS) lets you measure at the limits of physics with readings down to kT (-177 dBm/Hz). The N5511A PNTS is a replacement for the gold-standard Keysight E5500 phase noise measurement system and is designed to meet the needs of phase noise power users.
