The Keysight/Agilent/HP E1326B is a B-size VXI multimeter module delivering 5.5-digit resolution in a compact 2-slot form factor. Electrically identical to the E1411B, this register-based instrument integrates into standard VXI mainframes for automated test and data acquisition. Dual measurement paths—a low-noise 5.5-digit integrating ADC and a 13 kHz high-speed sampling ADC—enable flexible test strategies. Balanced, differential, and isolated inputs ensure signal integrity across DC and AC measurements. Optional internal installation via kit E1326-80004 or Option 009 preserves external slots in space-constrained systems.
