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. Currently, competing PXI VNA products reach only 8.5 GHz, occupy two or three slots, and cost significantly more than Keysight’s 9-GHz model.FREQUENTLY ASKED QUESTIONS - Network Analyzers What is a VNA?

Six models are available, providing frequency coverage from 300 kHz to 4, 6.5, 9, 14, 20 or 26.5 GHz. To address applications such as high-volume device testing and highly complex on-wafer testing, a single chassis can be loaded with up to sixteen PXI VNA modules for use as either multiple two-port VNAs, a single 32-port VNA, or any combination in between. When space is at a premium, full two-port VNA capability with S-parameters can be added to an existing system that has just one open slot. This enables the PXI VNAs to perform fast, accurate measurements and reduce the cost-of-test by enabling simultaneous characterization of many devices – two-port or multi-port – using a single PXI chassis. The new analyzers offer the best PXI VNA performance on key specifications such as speed, trace noise, stability and dynamic range.
