Agilent/Keysight E1465A

The Agilent/Keysight E1465A is a VXI relay matrix switch module that provides signal routing and switching control within VXI-based test systems. As a C-size, 1-slot, register-based module, it implements a 16×16 two-wire switching matrix capable of handling up to 1 A and 200 V across analog and digital test applications. The E1465A integrates legacy GPIB equipment into modern VXI architectures and supports expandable matrix configurations through chaining cables and interconnected terminal blocks.

– Key Features

• Scalability: Rows and columns expand to larger matrix configurations using chaining cables
• High-Density Integration: Up to 3072 two-wire crosspoints in a fully populated E1401B 13-slot mainframe
• Modular Design: Four E1465A modules interconnected with 16 daisy-chain expansion cables create a 32×32 matrix
• Cross-Family Compatibility: Shares switch card with E1466A and E1467A modules; matrix topology determined by terminal block selection
• Field Reconfiguration: Terminal blocks obtainable separately to modify matrix topology without module replacement

– Typical Applications

• Complex signal routing in VXI test architectures
• Analog and digital test switching
• Legacy GPIB instrument integration
• Multi-channel signal management

– Compatibility & Integration

The E1465A row and column expansion capability enables interconnection with E1466A and E1467A modules. Expansion uses chaining cable P/N E1466-80002 for 16×32 configurations and supports larger custom matrix topologies within standard VXI mainframes.
