Bird Technologies AT-800 Datasheet

Antenna Tester

AT-500, AT-800 Series

The Bird’s® AT-Series Antenna Testers provide 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 ideal for use in the field.

}

Tests the system in VSWR, Return Loss, Match Eciency, or Reection Coecient (Rho)

}

Single frequency readings and frequency sweeps allow for everything from pinpointests to system

optimization and tuning.

}

Can save up to 12 traces for comparison and tracking over time.

}

RS232 Interface allows communication.

APPLICATIONS

Ideal for use when a ruggged eld instrument is required to validate,

test and troubleshoot antenna systems.

PROBLEMS } SOLUTIONS

Harsh environment

} Military grade instrument

Extended field use

} Long battery life

Antenna failure

} Multiple measures to identify failure mode
