New N5511A PNTS enables Power Users to optimize and prove performance of new
designs, on schedule and on budget.
Santa Rosa, California - May 30, 2019 - Keysight Technologies, Inc. (NYSE: KEYS),
a leading technology company that helps enterprises, service providers and governments
accelerate innovation to connect and secure the world, today introduced a new phase
noise measurement system for "power users", which enables them to optimize and prove
performance of new designs, meet operational requirements, as well as remain on
schedule and on budget.
Phase noise is an unwanted phase modulation
noise that emerges in nearly all radio frequency and microwave devices including
oscillators, mixers, dividers, multipliers and amplifiers. Power users, including
professionals responsible for developing high-performance aerospace and defense
applications as well as cutting-edge device characterization for 5G and other wireless
communication systems, need to validate the phase noise performance of their designs.
Keysight's new N5511A Phase Noise Test System (PNTS) models are available in
three frequency ranges - from 50 kHz and going up to 3, 26.5, or 40 GHz with offsets
from .01 Hz to 160 MHz internally. It can be configured for either single or dual-channel
operation and offers the following key technology features:
Flexible architecture for easy integration of external reference sources enabling
users to select from a variety of commercially-available low-noise sources Phase
detector (quadrature) technique maximizes dynamic range Best-in-class absolute and
residual measurements on both continuous wave and pulsed signals Cross spectral
averaging (cross-correlation) to measure noise approaching the limits of physics,
down to the kT (–177 dBm/Hz) thermal noise floor, by removing uncorrelated noise
between two channels and enabling users to see the real performance of their device
"In terms of radio frequency and microwave design, less phase noise means more
performance, and the new Keysight N5511A PNTS can help customers achieve that performance,"
said Dan Dunn, vice president and general manager of Keysight's Aerospace Defense
and Government Solutions Group. "Its flexible architecture lets customers integrate
exceptional reference sources – theirs or ours – and confidently solve specific
The flexible and scalable architecture of Keysight's N5511A PNTS enables power
Confidently and quickly solve specific challenges in phase noise by removing
uncorrelated reference noise, system noise and any additional uncorrelated noise
from signal conditioning devices such as attenuators and amplifiers Generate faster
measurements using hardware acceleration with fast Fourier transform (FFT) and cross-correlation
in a Field Programmable Gate Array (FPGA), rather than software on a CPU Simplify
set-up of residual measurements using the phase noise measurement interface (PNMI)
accessory Stay ahead of the leading edge in metrology and calibration and adapt
to future needs by upgrading from single channel to dual channel (for cross-correlation)
and integrating other PXI modules for new functionality
Consisting of phase detector and data conversion modules housed in a custom,
low-noise single PXIe mainframe four units (4U) high, the N5511A occupies minimal
rack space. The system software included runs on an integrated PC controller using
the Microsoft Windows 10 operating system.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed
formulas and reference material while performing my work as an RF system and circuit
design engineer. The World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps
while typing up your telephone line, and a nice lady's voice announced "You've Got
