The Agilent/Keysight E1364A is a 16-channel VXI multiplexer module featuring latching armature relays for signal routing in automated test systems. This B-size, 1-slot register-based module provides Form C (SPDT) switching per channel with normally closed, normally open, and common contact terminals. Designed for data acquisition and control applications, the E1364A maintains switch positions without power and delivers high DC isolation for measurement integrity.
Technical Specifications
The module handles DC and AC signals up to 250 V, with AC peak ratings of 354 V. Maximum switching current is 1 A per non-inductive switch for both DC and AC RMS operation. Closed-channel resistance measures less than 1.5 Ω typically, extending to 3.5 Ω at end of life. The module exhibits a typical bandwidth of 10 MHz and channel-to-channel capacitance below 20 pF. Crosstalk performance reaches < −80 dB below 100 kHz and < −30 dB below 10 MHz. DC maximum thermal offset is 7 µV. Insulation resistance exceeds 10⁷ Ω at 40°C and 95% relative humidity, and exceeds 10⁸ Ω at 25°C and 40% relative humidity.
– Key Features
