The Bird 4480A is an element-free RF Wattmeter for CW/Digital transmissions. The 4480A is more than just a tool; it’s a game-changing solution designed to meet the rigorous demands of today’s RF measurement landscape. With true average power measurements for both Continuous Wave (CW) and digitally modulated signals, the 4480A ensures unparalleled precision across critical frequency spans from 2MHz to 30MHz and 25MHz to 1000MHz – without the need for traditional, cumbersome elements.

The robust design and versatile capabilities of the 4480A make it the ideal tool for professionals who require consistent and precise measurements in challenging environments. 

Power Measurement:

• Forward (FWD)
• Reflected (RFL)
• Voltage Standing Wave Ratio (VSWR)

Accurate measurement of forward and reflected power, as well as VSWR, is essential for ensuring reliable communication and system performance.

Three-Button Interface

• On/off, Switch high/low band, Backlight

Designed for easy use in various conditions, allowing operation with gloves and in low light. The 4480A provides a smooth and efficient user experience. 

At the input and output of the line section are Bird Quick-Change type RF connectors, which may be quickly interchanged with any other Bird “QC” connectors. Optional QC connectors are available to allow the 4480A to interface with a wide range of RF connector types.
