Today’s communication systems (e.g., 5G and Wi-Fi) utilize high order modulation to achieve high data throughput. Higher throughput requires faster clock rates, which make these systems more sensitive to local oscillator (LO) phase noise. This sensitivity can degrade EVM, increase symbol errors, and limit overall performance, underscoring the importance of minimizing phase noise for high-integrity communications.
In radar systems, excessive LO phase noise can mask weak return signatures and reduce a radar receiver’s ability to resolve Doppler-shifted target information. Minimizing phase noise is therefore critical for improving receiver sensitivity and target detection.
This demonstration highlights both ultra-low phase noise signal generation with the Maury Microwave HSX9100 series multi-channel RF synthesizer and precision phase noise measurement, featuring the Maury HA7162D series real-time phase noise analyzer. The stable, spectrally pure output of the HSX9100 series can be used as an LO substitute during testing to evaluate its impact on system performance, whether in communication links or radar receivers, while the high-performance HA7162D can measure the phase noise improvement directly to find a suitable replacement LO.

Product Overview
HSX9100 Series Multi-channel RF Synthesizer
The HSX9100 series offers exceptional phase noise and spectral purity performance as a multi-channel CW signal source. The compact 1U chassis allows for anywhere from 1 to 4 independently tunable channels (frequency/phase offset/amplitude) to optimize channel density within test system racks where real estate is often crucial.
KEY SPECIFICATIONS AND FEATURES:
- Fully independent channel
- Phase coherent channels
- The ultimate in channel-to-channel stability
HA7162D Real-time Phase Noise Analyzer
The HA7162D real-time phase noise analyzer offers a unique combination of accuracy, speed, flexibility, and reliability in a compact form factor. Control is easy through an intuitive GUI or simple remote commands. The real time engine covers the full measurement bandwidth with extremely fast measurement speeds to reduce product development time and optimizes ATE manufacturing throughput.
KEY SPECIFICATIONS AND FEATURES:
- Automated absolute and additive (residual) measurements
- Real-time cross correlation
- Only analyzer available that allows actual noise floor measurement
