Our high-end PNA family provides unrivaled excellence in measurement integrity and repeatability.Keysight offers five different types of network analyzer families ranging from high-end to compact: The resulting transmission and reflection measurements, impedance, and s-parameters enable test engineers to characterize their DUT. To assess the device’s effect on the current and voltage, a VNA measures both the amplitude and phase responses caused by the device. The receivers detect changes to the output signal from a device (or network) and compare that to the source signals input into that device. Network analyzers include both signal sources and receivers.

A VNA captures transmission (transmission coefficient, insertion loss, gain), reflection (reflection coefficient, VSWR, return loss), and impedance measurements, as well as the s-parameters S11, S12, S21, S22.

Network analyzers provide calibrated stimulus signals to the RF network or device under test (DUT) and measure the vector response over the frequency with phase and amplitude information. Network analyzers are the go-to instrument to conduct transmission, reflection, and impedance measurements, as well as s-parameter measurements during both the design and production processes.įor more information, check out: What is a Network Analyzer?Ī network analyzer conducts component characterization tests. They are essential for radio frequency (RF) and microwave component analysis of various passive and active devices including filters, antennas, and power amplifiers. Vector network analyzers (VNAs) are test instruments that measure electrical network parameters. FREQUENTLY ASKED QUESTIONS - Network Analyzers What is a VNA?
