The Keysight (Agilent) 467A is a dual-function power amplifier and regulated DC supply instrument for laboratory and production test environments. Operating from DC to 1 MHz, it delivers 10 W peak output power with selectable gain stages (X1, X2, X5, X10) or continuous variable gain from 0 to 10, making it suitable for signal conditioning, transducer excitation, and precision power sourcing applications. The unit combines low distortion amplification with stable DC output across five voltage ranges, all from a compact footprint drawing under 35 W at full load.
