This capability, a market first, reduces test times by a factor of 10 to 500. Incorporating this function into a VNA simplifies system connections and saves time by integrating high-speed spurious signal measurements into the instrument used to characterize S-parameters, compression, and distortion in satellite equipment, defense electronics, and commercial mobile devices.
Engineers often spend a considerable amount of time performing spurious signal measurements, resulting in trade-offs between test duration and coverage. With its new high-performance spectrum analyzer capability, a Keysight PNA can perform rapid spurious scans across a wide frequency band, improving test speed by up to 500 times compared to existing approaches. Measurement results are comparable to those obtained with the most sophisticated and fastest standalone spectrum or signal analyzers currently available.
The VNA can also perform simultaneous spectrum measurements on all test ports. This unique, market-first capability reduces design cycle time by enabling the characterization of mixers, converters, amplifiers, modules, or subsystems with a single connection. Measurement examples include LO, RF, and IF interface connections, harmonics, intermodulation products, and other higher-order mixing products.
Measurements on fixtures and wafers benefit from VNA calibration and disaggregation, which corrects receiver-response errors and also eliminates the effects of cables and fixtures. The resulting improvement in test accuracy allows for tighter test margins and more precise device specifications.
“The ability to perform high-performance spectrum and network measurements with a single instrument provides unprecedented insights into the device under test,” said Steven Scheppelmann, PNA Marketing Manager for Keysight’s Component Testing Division. “By replacing the separate switching array and spectrum analyzer, this innovation also addresses a growing need: reducing the size of component characterization test systems.”.
Keysight's VNAs are the ultimate expression of the company's expertise in linear and nonlinear device characterization. From R&D to the production line, the PNA family offers unparalleled excellence in measurements and design.
Prices and availability in the United States
Spectrum analyzer capability is now available. Pricing starts at $15,000 for an 8.5 GHz PNA-X and $30,000 for a 26.5 GHz PNA or PNA-X. This new functionality is available as an upgrade for customers with existing products, though it may incur additional costs related to CPU, operating system, or digitizer upgrades.
