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.
Designed for phase noise power users at the high end of the market
Flexible architecture lets you integrate exceptional reference sources — yours or ours — and confidently solve specific challenges faster
Multi-segment hardware cross-correlation in field programmable gate array (FPGA)
Absolute and residual phase noise using the phase detector (quadrature) method and cross-spectral averaging (crosscorrelation) for sensitivity down to the kT thermal phase noise floor (-177 dBm/Hz)
