RigExpert AA-520 is a powerful antenna analyzer designed for testing, checking, tuning or repairing antennas and antenna feedlines in 1 to 520 MHz range.
Mainly, this is SWR (Standing Wave Ratio) and impedance measurement instrument (impedance analyzer).
Easy-to use measurement modes, as well as additional features such as memory storage and connection to a personal computer, make the AA-520 attractive for professionals and hobbyists. It is quite important that graphical display of various parameters over a wide frequency range is a key feature of this analyzer which significantly reduces the time required to adjust an antenna. The new MultiSWR™ mode is unique for this antenna analyzer.
MultiSWR mode: RigExpert Antenna Analyzers have a unique ability to display SWR for up to five different frequencies at a time.
The following tasks are easily accomplished by using RigExpert AA-520:
Rapid check-out of an antenna
Tuning an antenna to resonance
Antenna SWR and impedance measurement and comparison before and after specific event (rain, hurricane, etc.)
Making coaxial lines or measuring their parameters
Cable fault location
Measuring capacitance or inductance of reactive loads
