Network analyzers – advanced tools for diagnostics and characterization of high-frequency systems

In the measurement and diagnostics of high-frequency signals, equipment enabling precise examination of radio, microwave, and transmission system parameters is essential. Network analyzers – including vector network analyzers (VNA), spectrum analyzers, and their mobile counterparts – are fundamental equipment in research and development laboratories, quality control departments, telecommunications service centers, and technical universities. The Kamami store offers modern measuring devices that enable accurate analysis of frequency response, impedance measurements, attenuation, reflection coefficient, and spectral analysis of signals. The available models, both stationary and portable, combine advanced technology with intuitive operation and a compact form, making them an ideal solution for engineers, technicians, and electronics specialists working both in the field and in laboratories.

What is a network analyzer and what functions does it perform?

A network analyzer is a specialized measuring device used to examine the parameters of transmission systems – including lines, antennas, filters, amplifiers, or RF components – as a function of frequency. In the case of vector network analyzers (VNA), it is possible to measure both the amplitude and phase of the signal simultaneously, which allows precise impedance characterization and measurement of S-parameters (Scattering Parameters). Spectrum analyzers enable spectral analysis of electrical signals – detection of interference, unwanted emissions, harmonics, or intermodulation. Portable versions of these devices allow such measurements to be carried out in the field – e.g., when tuning an antenna on a mast, testing transmission lines, or examining radio equipment without the need to transport samples to a laboratory.

Vector network analyzers (VNA) – full characterization of RF systems

Vector Network Analyzers are key tools in the study of high-frequency systems. They allow the measurement of both amplitude and phase across two or more ports, enabling analysis of reflections, attenuation, impedance matching, and transmission characteristics of circuits. These devices are indispensable in the design and testing of antennas, power amplifiers, RF filters, impedance transformers, and many other components operating in ranges from tens of kHz to several GHz. Kamami offers both compact VNAs for laboratory use and lightweight, mobile USB-powered models ideal for field operations.

Portable network analyzers – mobility and functionality in one device

Modern portable network analyzers combine the performance of traditional laboratory equipment with the advantages of a mobile design. With battery power, lightweight construction, and built-in touchscreens, they enable quick measurements without the need for an external computer. They are widely used by technicians servicing telecommunications infrastructure, radio systems, base stations, as well as by radio amateurs and field engineers. Some models offer measurement data logging, USB and Bluetooth interfaces, and the ability to connect near-field probes or calibration heads.

Spectrum analyzers – accurate analysis of signals and interference sources

Spectrum analyzers are used to display the frequency distribution of a signal – both analog and digital – allowing assessment of transmission quality, identification of interference, and measurement of signal power in specific bands. They are used in telecommunications, radio electronics, EMC testing, compliance measurements, and RF system diagnostics. The devices available in Kamami’s offer enable analysis across a wide frequency range, often with resolution down to a few Hz, allowing the detection of even weak and narrowband interfering signals.

Adapted to various environments – from laboratory to field

All analyzers offered by Kamami are characterized by robust construction, resistance to interference, and high stability of measurement parameters. Mobile devices are equipped with surge protection, sealed housings resistant to dust and moisture, and interfaces enabling fast data transfer to computers or mobile devices. Thanks to this, these analyzers can be used in demanding field conditions while maintaining full precision and reliability.
