Agilent / Keysight E1467A 8 x 32 Relay Matrix Switch

The Keysight E1467A is a C-size, 1-slot VXI relay matrix switch delivering 256 two-wire crosspoints in an 8×32 configuration. Built on latching armature relays and register-based control, this module executes non-blocking signal routing with sub-millisecond switching speed. The E1467A scales through matrix expansion via chaining cables, enabling larger configurations—three units create an 8×96 matrix, and a full 13-slot mainframe supports up to 3072 crosspoints. QUIC terminal blocks provide field-configurable topology selection.

• Open column-to-column: −82 dB (<10 kHz), −64 dB (<100 kHz), −50 dB (<1 MHz)

– Key Features

• Scalable Architecture: Supports expansion to larger matrices via optional chaining cable (e.g., E1466-80002) or expansion terminal blocks (Options 201/211)
• Compatible Core: Shares switch card topology with E1465A and E1466A models for flexible system integration
• Multi-Protocol Control: GPIB, RS-232, and VXIplug&play interfaces
• Software Support: LabVIEW, Agilent VEE, MATLAB, and C/C++
• Relay State: Relays open at power-up

– Typical Applications

• Automated test systems requiring high-density signal routing
• Data acquisition and multiplexing
• General-purpose two-wire switching and matrix expansion

– Compatibility & Integration

The E1467A integrates into standard VXI mainframes and chains with E1465A and E1466A modules. Matrix expansion degrades crosstalk and bandwidth; worst-case specifications apply to expanded configurations.
