Vector network analyzers

General information

Network analyzers are designed to evaluate the impedance or scattering and reflection characteristics of active and passive devices such as antennas, amplifiers, filters, frequency converters, switches, attenuators and many other components used in various systems.

Vector network analyzers (VNA) are the most powerful in their group, as they measure a full set of amplitude and phase characteristics of devices. These parameters include: S-parameters, transfer functions, amplitude and phase, standing wave ratio (SWR), insertion loss or gain, attenuation, group delay, return loss or reflection coefficient. Modern vector analyzers usually allow measurements in the frequency range up to 43 GHz, some models provide an upper range of 70 GHz, and with additional modules the upper range can be extended to 145 GHz and higher.

Additional equipment

Typically, when working with a network analyzer, calibration kits and various accessories are used. This additional equipment is presented in the section: microwave accessories. Also note that most analyzer models can be equipped with additional useful options that significantly expand the functionality of the device, but at the same time, increase its cost.

Manufacturers of measuring equipment regularly develop and launch new models of vector network analyzers with expanded capabilities and improved performance. Some time after the start of sales of new models, old models and series are discontinued. A complete list of discontinued network analyzers, including proposed replacements, can be found here: discontinued network analyzers.

Basic theory

Buying an inexpensive and high-quality vector network analyzer is not always easy. When choosing a model, in addition to the standard parameters: frequency range and number of ports, it is necessary to take into account additional characteristics and capabilities of the analyzer: dynamic range, measurement accuracy, measurement speed, resolution, source power, directivity, calibration modes, possibility and ease of programming, built-in digital interfaces, a set of additional functions, operating temperature range, quality and durability of the device, the reputation of the manufacturer, the professionalism and reliability of the supplier, the availability of a service center, warranty period and much more. In addition, you may need technical advice on additional accessories: calibration elements, phase-stable cables, waveguides and adapters.
