Keysight VNA accelerates spurious search by up to 500 times
Keysight Technologies today announced a new capability that adds a high-performance spectrum analyzer to its PNA and PNA-X Series microwave vector network analyzers (VNAs). This industry-first capability reduces test times by a factor of 10 to 500 times. Incorporating this functionality into a VNA simplifies system connections and saves time by putting high-speed spurious measurements in the instrument used to characterize S-parameters, compression, and distortion in satellite equipment, defense electronics, and commercial wireless devices.
It is often time consuming for engineers to perform spurious measurements, thus forcing tradeoffs between test time and test coverage. With the new high-performance spectrum-analyzer capability, a Keysight PNA can perform fast spurious searches across a broad frequency band, improving test throughput by as much as 500 times compared with existing approaches. Measurement results are comparable to those obtained with today’s fastest, most sophisticated standalone spectrum or signal analyzers.
The VNA also can perform simultaneous spectrum measurements on all test ports. This unique, industry-first capability reduces design cycle time by enabling one-connection characterization of mixers, converters, amplifiers, modules or subsystems. Example measurements include LO, RF, and IF feedthrough; harmonics; intermodulation products; and other higher-order mixing products.
In-fixture and on-wafer measurements gain the benefits of VNA calibration and de-embedding, which correct receiver-response errors and also remove cable and fixture effects. The resulting improvement in test accuracy makes it possible to achieve narrower test margins and tighter device specifications.
“The ability to make high-performance spectrum and network measurements in one instrument enables unparalleled insight into the device under test,” said Steven Scheppelmann, PNA marketing manager for Keysight’s Component Test Division. “By replacing a switch matrix and standalone spectrum analyzer, this innovation also addresses the increasingly important need to reduce the size of component-characterization test systems.”
Every Keysight VNA is an expression of the company’s expertise in linear and nonlinear device characterization.
The spectrum analyzer capability is available now. Prices start at $15,000 for an 8.5-GHz PNA-X and start at $30,000 for a 26.5-GHz PNA or PNA-X. This new functionality is available as an upgrade for installed-based customers, however this may also require additional costs for CPU, operating system, or digitizer upgrades.
