The Wandel & Goltermann AT462 is a precision step-attenuator bank designed for telecommunications calibration in both balanced and coaxial circuits. Offering discrete attenuation steps, typically 1 dB, across a range like 0–30 dB, it provides stable performance under varying conditions due to its rugged mechanical build.
Compatible with 2-wire (600 Ω) and 4-wire telecom lines, it's ideal for lab and field use, especially when paired with SPM-series level meters for precise alignment tasks.
