4421A Series, Multifunction RF Power Meters
Precision You Know. Smarter and Compact - Bird's 4421A Power Meter combines precision measurement with a modern touchscreen interface, delivering fast, reliable RF power readings in real time. Designed for ease of use, it supports a wide range of Bird sensors to meet evolving test and calibration needs. In a market where every wafer counts, make every measurement matter. Precision isn’t a luxury in your fab it’s a requirement. A slight deviation in RF power during etch or deposition can impact layer integrity, reduce uniformity, and ultimately lower your yield. Without accurate, repeatable power measurement, process drift becomes inevitable, and quality control suffers.
The Bird 4421A delivers the high-resolution data and real-time insight you need to maintain tight process windows, qualify tools faster, and catch anomalies before they affect production. It’s not just about measuring power it’s about protecting throughput, consistency, and the bottom line.
Dual Sensor Inputs for Flexible Workflow
Switch between two sensors without swapping cables or reconfiguring setups. The 4421A supports dual input channels, saving time and increasing throughput during testing.
Built-In Graphing for Smarter Measurements
Visualize power behavior in real time. The 4421A’s graphing capability lets you confirm that your device under test has fully settled before taking a final reading reducing error and improving consistency.
Backward-Compatible with Proven Sensors
Upgrade without overhauling. The 4421A is fully compatible with Bird’s trusted precision sensors, letting you preserve your investment while gaining modern performance.
