DESCRIPTION:

The Bird Technologies 4421A-12-11-1 Dual Sensor Multifunction Power Meter is a versatile RF measurement instrument designed to support two Bird RF power sensors concurrently, enabling efficient, side-by-side monitoring of RF power parameters. This model is equipped with both RS-232 and LAN (Ethernet) interfaces, making it suitable for integration into automated test systems, networked laboratories, and remote monitoring environments.

The meter supports average power, peak power, and directional power measurements depending on the connected sensors. When paired with directional sensors, it provides forward and reflected power readings and calculates essential RF performance metrics such as VSWR and return loss, offering rapid insight into antenna and transmission line behaviour. Dual-sensor operation allows simultaneous measurement at two points in an RF chain or direct comparison between sensors.

Designed for reliable use in laboratory, production, and field service applications, the 4421A-12-11-1 delivers consistent measurement performance across frequency and power ranges defined by the attached sensors. Key characteristics include dual-sensor capability, support for average and peak measurements, combined RS-232 and LAN connectivity, compatibility with Bird’s extensive range of directional and wideband RF sensors, and sensor-based calibration to ensure stable, repeatable results.

Typical Use Suitability:
Ideal for networked and automated RF power measurement, system commissioning, comparative testing, and remote diagnostics in communications, broadcast, and industrial RF environments where LAN and RS-232 control are required.
