RigExpert AA-650 ZOOM

The RigExpert AA-650 ZOOM is a powerful antenna analyzer designed for testing, checking, tuning, or repairing antennas and antenna feed-lines.

Mainly, these are SWR (Standing Wave Ratio) and impedance measurement instruments (vector impedance analyzers). Their large, bright LCD screens provide graphic illustration of SWR, impedance; return loss, and much more.

Easy to use measurement modes, as well as additional features such as connection to a personal computer (to plot Smith charts, etc.); make RigExpert analyzers attractive for professionals and hobbyists alike. They are compatible with several operating systems, including Windows© 10.

The graphic display of various parameters over a wide frequency range is a key feature of these analyzers. This significantly reduces the time required to adjust an antenna. Their various ZOOM models even allow you to zoom-in on graph points for clearer analysis. USB connection allows export of sweep files with AntScope software to PC or MAC. Some models have Bluetooth for direct file transfer without USB cable, for galvanic isolation which provides the most accurate measurements.

RigExpert Antenna Analyzers are available in several models and in various frequency ranges of operation. Each is fitted with an SO-239 female connector, except for those models that will operate at 230 MHz and above, where a Type N connector is more efficient. An array of options are available to cover HF, UHF, and VHF bands.

The following tasks are easily accomplished by using RigExpert Antenna Analyzers:

* Rapid check-out of an antenna
* Tuning an antenna to resonance
* Antenna SWR and impedance measurement and comparison before and after a specific event (rain, hurricane, winter, etc.)
* Making coaxial lines or measuring their parameters
* Cable testing and fault location
* Measuring capacitance or inductance of reactive loads
*Send data to laptop for larger graphical display and further analysis.

Note: For additional product information, please look at the files under the “Documentation” tab.

When you need a versatile antenna analyzer for Amateur Radio or professional use, you’ll find that one of these RigExpert Antenna Analyzers, from DX Engineering, will be well suited to the task!
