Vector network analyzers (VNAs) are invaluable test tools for characterizing active and passive RF and microwave components and determining how they affect signals passing through them. By leveraging modern IC and circuit technologies, along with significant advancements in VNA technology, high-performance capabilities in a portable form factor are now attainable.

This paper explores various phase noise measurement methods and introduces a test solution that provides high-volume-production phase noise measurement speed and accuracy across wide frequency and dynamic ranges. The process employs cross-correlation technology to achieve low phase noise measurement levels at offset frequencies close to and far from the carrier.

As wireless applications grow, the needs for spectrum monitoring and interference hunting grow with them. In some applications, interference can be life-threatening. Portable spectrum analyzers are invaluable interference hunting tools.
