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 diagrams, etc.), makes RigExpert 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 this analyzer:

• Rapid check-out of antenna
• Tuning an antenna to resonance
• Antenna SWR and impedance measurement and comparison before and after specific event (rain, hurricane, etc.)
• Making coaxial stubs or measuring their parameters
• Cable testing and fault location
• Measuring capacitance or inductance of reactive loads

 A built-in ZOOM capability makes graphical measurements especially effective.
