Bird’s 4421A Power Meter combines precision measurement with a modern touchscreen interface, delivering fast, reliable RF power readings in real time. Designed for ease of use, it supports a wide range of Bird sensors to meet evolving test and calibration needs.
Dual Sensor Inputs for Flexible Workflow
Switch between two sensors without swapping cables or reconfiguring setups. The 4421A supports dual input channels, saving time and increasing throughput during testing.
Built-In Graphing for Smarter Measurements
Visualise power behaviour in real time. The 4421A’s graphing capability lets you confirm that your device under test has fully settled before taking a final reading—reducing error and improving consistency.
Backward-Compatible with Proven Sensors
Upgrade without overhauling. The 4421A is fully compatible with Bird’s trusted precision sensors, letting you preserve your investment while gaining modern performance.
