DESCRIPTION:

The Bird Technologies 4421A-10-11-0 Single Sensor Multifunction Power Meter is a versatile RF measurement instrument designed for use with a single compatible Bird power sensor, providing accurate average, peak, and directional power measurements depending on the sensor type connected. This variant includes both RS-232 and LAN (Ethernet) communications, enabling integration into automated test systems, remote monitoring setups, and networked laboratory environments.

The meter supports measurement of forward and reflected power when paired with directional sensors and can calculate essential RF system parameters such as VSWR and return loss, allowing rapid assessment of transmission line and antenna performance. Its digital display and straightforward user interface allow for quick setup and clear presentation of real-time measurement data in both bench and field applications.

Designed to operate across a wide range of frequencies and power levels as defined by the connected sensor, the 4421A-10-11-0 offers flexibility across communications, broadcast, industrial, and general RF maintenance environments. Key characteristics include single-sensor operation, support for average and peak power, network and serial control via LAN and RS-232, and compatibility with Bird’s extensive portfolio of directional and wideband RF power sensors. Calibration accuracy is maintained through sensor-based calibration, ensuring stable and repeatable measurement performance over time.

Typical Use Suitability:
Well suited for automated and networked RF test systems, production testing, transmitter maintenance, and remote RF power monitoring where LAN or RS-232 control is required alongside reliable multifunction power measurement.
