4480A, Element-Free Digital-Ready

RF Power Meter

Beyond Simple Signals: Master Digitally Modulated Formats

The Bird 4480A Wattmeter redefines RF power measurement with precision and simplicity. Its element-free design delivers accurate true average power measurements for Continuous Wave (CW) and digitally modulated signals from 2 MHz to 30 MHz and 25 MHz to 1000 MHz. Switch between Watts and dBm effortlessly. With added Return Loss (RL), plus Forward Power, Reflected Power, and VSWR, it consolidates critical data for seamless operation and performance.

Ideal for telecommunications, broadcasting, industrial RF systems, research and development and more, the 4480A is built for demanding environments, offering unmatched accuracy (±4%) and power handling up to 10,000 Watts.
