DESCRIPTION:
The Bird Technologies 4421B540-2 Interface Module is a precision RF sensor interface designed to connect Bird 4020 Series, 4027 Series, and 4028 Series precision RF power sensors directly to a computer. When paired with Bird’s Virtual Power Meter (VPM) software, this module enables real-time display, logging, and analysis of sensor measurements — including multiple sensors simultaneously — without using a traditional RF power meter.
The interface supports both USB 2.0 Type B and Serial RS-232 connections, making it suitable for modern PCs as well as legacy systems. It accepts input from compatible sensors via a Latch-n-Lock connector and provides power and communication pathways for forward and reflected power measurements, VSWR data, and related RF sensor metrics. Standard accessories include interface cables, a power supply, and USB connectivity hardware, allowing immediate integration into test setups.
The 4421B540-2 simplifies data acquisition and automation workflows by enabling both graphical and programmatic access to sensor data, which can be incorporated into custom applications or logged through Bird’s VPM software. It is ideal for engineers and technicians who require flexible, computer-based RF power analysis using Bird precision sensors.
Key specifications include measurement support for forward and reflected average power and VSWR, a frequency range of 100 kilohertz to 3 gigahertz (sensor dependent), and a power range from 100 milliwatts to 25 kilowatts (sensor dependent), ensuring broad compatibility with Bird’s sensor families.
