Boonton 4210-4E RF Microwattmeter

The Boonton 4210-4E is a single-channel RF power meter designed for precision power measurements across a broad frequency spectrum. It operates in conjunction with various Boonton 4210 Series sensors, enabling measurements from nanowatts to milliwatts. The instrument offers a wide dynamic range and multiple measurement modes, including power (Watts) and decibels (dBm or dBr). Its microprocessor-based design facilitates automatic ranging, auto-zeroing, and provides a 3.5-digit LED display for clear readings. The Boonton 4210-4E is engineered for both manual and system applications, prioritizing ease of use and reliability in RF and microwave testing and calibration.
