Description
Product Overview
For component impedance characterization, the Keysight E4981B combines test frequency: 120 Hz / 1 kHz / 1 MHz (E4981B-002 or -001 configuration), basic accuracy: C-D measurement: 0.05% vs. 0.0005 (spec), measurement speed: 2.3 ms@1 MHz; 3.0 ms@1 kHz; 11.0 ms@120 Hz, test signal/offset: Supports test signal level compensation and 1 MHz ±1%/±2% frequency shift, and measuring range/function: 0 F to 2.0 mF (segmented by test frequency) in a production high speed capacitance meter platform. It is part of the E4981B Capacitance Meter. It can also be evaluated for materials and device research and production quality testing. Exact options, interfaces, accessories, calibration scope, and regional availability depend on the ordered configuration and should be confirmed before purchase.
