SV-4401A from 50 kHz to 4.4 GHz

VNA SV-4401A is a portable vector network analyzer (VNA) with a frequency range of 50 kHz to 4.4 GHz. Featuring a 7” high-brightness IPS capacitive touchscreen display. It can be used for S11 and S21 measurements. The S21 dynamic range of the SV4401A is 75 dB, while the S11 dynamic range is 50 dB, making it suitable for testing MF/HF/VHF/UHF antennas, such as shortwave antennas, ISM band antennas, WiFi antennas, Bluetooth antennas, GPS antennas, etc. It can also be used to measure filters, amplifiers, attenuators, cables, power dividers, couplers, duplexers, and other RF components.

A network analyzer is an indispensable tool for any amateur radio station, whether for radio or antenna applications. Vector network analyzers enable highly versatile measurements on RF devices, cables, and antennas. This makes it easy to measure the most important characteristics of antennas, filters, cables, resonant circuits, and other assemblies and can be used as time-domain reflectometry (TDR). Time Domain Reflectometry (TDR) technique helps to accurately locate a loss, variation, or interruption of the electrical signal with a resolution of a few centimeters
