The Agilent/Keysight E1411B is a C-size VXI multimeter module delivering 5.5-digit resolution for precision data acquisition and automated test systems. This 1-slot, register-based instrument features dual analog-to-digital converters: a low-noise integrating ADC for accurate DC and AC measurements, and a 13 kHz high-speed sampling ADC for dynamic signal capture. Electronically equivalent to the E1326B, the E1411B differentiates through its compact C-size form factor. The module supports multichannel scanning via integration with VXI relay or FET multiplexers, enabling synchronized programming of multimeter and multiplexer channels through single SCPI commands. Balanced differential isolated inputs and flexible triggering with built-in timer pacer simplify complex measurement sequences.
