Agilent/Keysight E1364A

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

• Latching relays maintain switch state during power loss
• Simultaneous channel switching capability
• Configurable internal +5 V (1 A limit) and +12 V (0.5 A limit) supplies for digital output applications
• Jumper and resistor configuration options for pull-up integration
• 16 independent SPDT channels with flexible contact routing
• VXI register-based control architecture

– Typical Applications

The E1364A serves automated test equipment requiring flexible signal multiplexing, digital output actuation, and high-voltage measurement isolation. Applications include multi-channel data acquisition systems, relay-based control circuits, and test sequences demanding state retention across power cycles.

– Compatibility & Integration

Designed for B-size VXI mainframes, the module operates in C-size mainframes with an adapter. Terminal blocks ship standard; connector blocks are available as options. VXIbus register-based programming enables integration with VXI test platforms.
