The Anritsu 60A50 SWR Bridge is a precision accessory for measuring Standing Wave Ratio (SWR) and return loss across RF systems from 5 MHz to 2 GHz. Operating as a Wheatstone bridge, it preserves both phase and amplitude of reflected signals, enabling accurate impedance mismatch assessment without a built-in RF detector. This design provides flexibility for low-level signal measurements requiring external RF amplification. The bridge delivers 40 dB directivity and 40 dB dynamic range with ±0.09% accuracy, making it suitable for component and system characterization in laboratory and field environments.
