DESCRIPTION:

The Bird Technologies 4421A-10-00-0 Single Sensor Multifunction Power Meter is a compact, high-accuracy RF power measurement instrument designed to operate with a single compatible Bird power sensor. It supports average power, peak power, and directional power measurements (sensor dependent), making it suitable for a wide range of RF testing, maintenance, and verification tasks.

The meter features a clear digital display and intuitive front-panel controls, allowing quick configuration and real-time readout of critical RF parameters. When used with directional sensors, the 4421A can display forward and reflected power and calculate key system metrics such as VSWR and return loss, providing immediate insight into RF system performance.

Engineered for both bench and field use, the 4421A-10-00-0 offers stable, repeatable measurements across a broad range of frequencies and power levels, as defined by the connected sensor. Its robust design and compatibility with Bird’s extensive sensor portfolio make it a flexible solution for communications, broadcast, industrial, and general RF test environments.

Key specifications include single-sensor operation, support for average and peak power measurement, compatibility with directional and wideband Bird sensors, and a form factor suited to portable or fixed test setups. Calibration integrity is maintained through sensor-based calibration, ensuring consistent and reliable measurement results.
