RigExpert AA-30 and AA-54 are powerful antenna analyzers designed for testing, checking, tuning or repairing antennas and antenna feedlines.
Mainly, these are SWR (Standing Wave Ratio) and impedance measurement instruments (vector impedance analyzers).
Easy-to use measurement modes, as well as additional features such as connection to a personal computer (to plot Smith charts, etc.), make RigExpert AA-30 and AA-54 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 these analyzers which significantly reduces the time required to adjust an antenna.
The following tasks are easily accomplished by using RigExpert AA-30 and AA-54:
- 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 testing and fault location
- Measuring capacitance or inductance of reactive loads
