Selection criteria for a VNA depend highly on the application or use case. Streamline USB VNAs have all the performance of a benchtop instrument, but at a fraction of the size.
The Streamline USB VNA enables a compact form factor with zero compromises. Customize the network analyzer's capabilities to only what you need and get fast, accurate multiport measurements. Modular PXI VNAs drive down the size of the test. Our handheld VNA enables benchtop precision in a rugged handheld unit. The FieldFox is the world’s most integrated handheld analyzer. ENAs balance speed, performance, and budget. 
Our midrange and economy ENA family drives down the test cost while providing reliable measurements, an intuitive UI, and upgradable instruments. PNA is the overall highest performing network analyzer in the industry. PNA-X maximizes measurement flexibility, replacing an entire rack of equipment. 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?
