VNAs Insights | Sumble

What is VNAs?

A Vector Network Analyzer (VNA) is an instrument that measures the network parameters of electrical networks. It is used to characterize microwave components such as filters, amplifiers, and antennas by measuring their S-parameters over a range of frequencies. VNAs are essential for design, testing, and manufacturing of RF and microwave circuits.

What other technologies are related to VNAs?

VNAs Competitor Technologies

spectrum analyzers

Spectrum analyzers measure the magnitude of an input signal versus frequency, while VNAs measure both magnitude and phase of a signal after it passes through a network. They both analyze frequency domain behavior, so they are competitors to a limited extent but VNAs provide richer characterization.

VNAs Complementary Technologies

power meters

Power meters measure the power of a signal. VNAs can measure power as part of their s-parameter measurements, but power meters are more specialized for accurate power measurement. Thus, they are complementary for full RF characterization.

signal generators

Signal generators create test signals used as stimulus, and VNAs measure the response to that stimulus from a DUT, so they work together for network analysis.

ADS

ADS (Advanced Design System) is circuit simulation software. Measurements done using VNAs may be compared to simulated results from ADS, to validate circuit models or debug design discrepancies, so they are complementary tools.
