The Keysight Technologies (formerly Agilent / HP) 4349B is a high-performance 4-channel high resistance meter designed for rapid, simultaneous testing of multiple device-under-test (DUT) components, such as capacitors. Offering high-speed measurements, basic accuracy of 0.6%, and built-in error correction, it is ideal for high-volume manufacturing environments.
