DESCRIPTION:

The Bird Technologies 4421A-20-00-0 Dual Sensor Multifunction Power Meter is a high-performance RF measurement instrument designed to operate with two compatible Bird power sensors simultaneously, allowing parallel measurement and comparison of RF power parameters. It supports average power, peak power, and directional power measurements depending on the connected sensors, making it well suited to complex RF test and monitoring applications.

With dual-sensor capability, the meter can display forward and reflected power from separate measurement points or sensors at the same time, enabling efficient evaluation of RF systems, transmission lines, and antennas. When used with directional sensors, it also provides calculated RF metrics such as VSWR and return loss, supporting rapid diagnostics and system optimisation.

The 4421A-20-00-0 is designed for reliable operation in laboratory, production, and field service environments. Measurement frequency range and power handling are defined by the attached sensors, allowing the meter to adapt across a broad range of RF applications. Key characteristics include dual-sensor operation, support for average and peak measurements, compatibility with directional and wideband Bird sensors, and a robust form factor suitable for bench or portable use. Calibration accuracy is maintained through sensor-based calibration, ensuring consistent, repeatable measurement performance.

Typical Use Suitability:
Ideal for simultaneous multi-point RF power measurement, comparative testing, system commissioning, and troubleshooting in communications, broadcast, and industrial RF environments where dual-sensor capability improves efficiency and insight.
