Model: 4480A (replaces 4410A)

Bird 4480A RF Wattmeter

The Bird 4480A Power Meter offers element-free, precise RF power measurements for CW and digitally modulated signals. It is designed for ease of use, delivering reliable performance across a wide range of applications from 2 MHz to 1000 MHz.

New in-line power measuring equipment intended for measuring incident and reflective power levels in watts across two frequency bands. The element-free design streamlines field operations by reducing maintenance needs and enhancing reliability, allowing personnel to focus on mission-critical tasks without the complexity of managing interchangeable elements.

Purpose: Ensuring radio readiness.
Connection: Inline RF power measurements between the transmitter output (RF source) and the load or antenna.
