The most affordable such instrument for some time has been NanoVNA. Please check also for other Vector Network Analyzers here.A Vector Network Analyzer (VNA) is an extremely useful tool for radio hobbyists as it allows you to measure and tune antennas and filters, as well as measure cables. Two antennas give you the opportunity to try the point-and-match function of the our VNA products, and measure the coupling between them. There are 1-port networks, 2-port attenuators, filters and an active amplifier component. It describe also what you see on the screen and why some of the measurements may look different from what the theory tells us. Also tutorial is included that will explain how to measure. Then you are ready to measure the different impedances and networks. You will start with a calibration of the measurement with the on-board UFL calibration kit. With VNA Sandbox beginners will get familiar with VNA measurements and also their meaning on the screen. Includes UFL sockets for your measurements.Above all it also great calibration tool. VNA Sandbox is learning tool for all Megiq VNAs. Moreover VNA-0440 can be used for automated production testing with VNA Application Programming Interface. PC-software, for controlling, saving data and set-ups, analysis, reporting, etc.It’s also ideal for on-site measurements. Thus using it near antenna or inside larger device or installation is simple. VNA-0440 has small size and it is lighweight. Its frequency range includes almost all popular telecom bands like GSM-GPRS-LTE, Wifi, DECT, GPS, ISM, Zigbee, Bluetooth and others. VNA-0440 is ideal for measuring all kinds of micro circuits like antennas, attenuators, amplifiers etc.
It is controlled from a PC through a USB connector because of simple controll. The VNA-0440 is full bi-directional 2-port Vector Network Analyzer. Description 4GHz 2-port Vector Network Analyzer
