AT-800
The AT-800, Antenna Tester provides a cost-effective, fast, graphical way of determining the quality of mobile and base station antennas.
· Rugged, easy-to-use, hand-held design with extended battery life makes it idealfor use in the field
· Tests the system in VSWR, Return Loss, Match Efficiency, or Reflection Coefficient (Rho)
· Single frequency readings and frequency sweeps allow for everything from pin-point tests to system optimization and tuning
· Can save up to 12 traces for comparison and tracking over time
· RS232 Interface allows communication
