Keysight / Agilent / HP E1411A 5.5-Digit Multimeter

The Keysight/Agilent/HP E1411A is a 5.5-digit VXI multimeter module designed for automated test systems requiring precision measurement and high-speed data acquisition. This C-size, 1-slot register-based instrument integrates directly into VXIbus mainframes and delivers flexible measurement capabilities across DC voltage, AC voltage, resistance (2-wire, 4-wire, offset-compensated), temperature, and frequency. Dual analog-to-digital converters—an integrating A/D for low-noise 5.5-digit resolution and a sampling A/D for high-speed 14-bit readings—enable operation across diverse measurement scenarios. With sampling rates to 13 kHz and external trigger support at up to 5 kHz minimum pulse width of 100 ns, the E1411A suits demanding laboratory and field-test environments. Autoranging simplifies operation, while software calibration and self-test diagnostics ensure instrument integrity. SCPI command language support enables seamless integration into automated test sequences. The module operates as a stand-alone instrument or combines with VXI relay or FET multiplexers to create multichannel scanning configurations. Balanced differential isolated inputs provide robust noise immunity. Safety and compliance certifications include IEC 1010-1, EN61010-1, CSA C22.2#1010.1, UL 3111, CISPR 11:1990/EN55011 (Group 1, Class A), EN50082-1:1992, with 4 kV contact discharge and 8 kV air discharge ESD protection per IEC 801-2, and 3 V/m radiated immunity per IEC 801-3.
