Product Overview

The Keysight 33502A (Agilent) is a dual-channel, high voltage output amplifier. It has an isolated analog front end with up to 50 Vpp (±25 V) output voltage range. It is also a very low-distortion amplifier with < 0.01% @ 10 kHz and 40 Vpp. The Keysight 33502A (Agilent) is designed to work as a companion for function generators to offer low-distortion, higher voltage outputs.
