Keysight E1460A 64-Channel High-Density Relay Multiplexer VXI Module

Description

Key Technical Specifications

Product Introduction & Supply Chain Strategy

The Keysight E1460A is a C-size, 1-slot register-based VXI multiplexer module engineered for high-density automated test equipment (ATE) environments, including wire harness testing, cable validation, and semiconductor characterization. Built with armature latching relays, it manages up to 128 single-ended or 64 differential channels without requiring continuous coil power, preserving signal integrity and thermal stability across demanding industrial measurement cycles.

Securing the E1460A as New Surplus is a vital supply chain hedge against catastrophic system downtime. Because OEM production is discontinued, maintenance teams face extreme stock-out risks. Refurbished modules carry hidden degradation, such as contact oxidation or high relay resistance, leading to intermittent signal failures. Procuring unused New Surplus units guarantees factory-level relay lifespans, zero contact wear, and verifiable zero-hour operation, lowering your Total Cost of Ownership (TCO) compared to the recurring downtime risks of second-hand alternatives.

Installation & Configuration Guide

Stage 1: Pre-Installation (Prep & Safety)

1. Power down the VXI mainframe chassis and isolate all external signal sources connected to the system.
2. Put on a grounded ESD wrist strap before handling the E1460A to prevent static damage to sensitive onboard register logic.
3. Inspect the QUIC screw terminal block (E1460-80011). Document existing field wiring and take clear reference photographs of the jumper header configurations on the terminal card before disconnecting cables.

Stage 2: Removal

1. Loosen the top and bottom retaining screws on the existing VXI module faceplate.
2. Unlatch the insertion/extraction levers to disengage the board from the VXI backplane backplate.
3. Slide the card straight out along the slot guides without applying lateral pressure to prevent bending the rear P1/P2 backplane connector pins.

Stage 3: Installation (Clone & Seat)

1. Replicate the wire-mode jumper configuration (1-wire, 2-wire, 3-wire, or 4-wire mode) on the replacement E1460A terminal block to mirror the failed unit.
2. Align the replacement E1460A module with the card guides of the target C-size slot.
3. Slide the card smoothly until the rear connectors contact the backplane, then press the faceplate levers firmly to seat the P1 and P2 connectors. Tighten the retaining screws securely.

Stage 4: Power-On & Testing

1. Reconnect the wired QUIC terminal block onto the E1460A component card.
2. Apply power to the VXI mainframe and observe the power-on self-test (POST) LEDs on the front panel.
3. Send a baseline SCPI query over the VXI bus (*IDN? or channel query) to verify register access and confirm zero backplane handshake errors before putting the rack into production.

Firmware/Software Versions & Upgrade Notes

• Driver Compatibility: Use VXIplug&play driver version A.02.10 or later for stable register communications across modern VISA architectures.
• Backward Compatibility: Version A.02.x drivers maintain backward compatibility with legacy A.01.01 driver calls, but verify command syntax if migrating from older HP-IB command translators.
• Firmware Maintenance Risks: The is a hardware-driven, register-based slave card (A16). Avoid flashing or modifying bus bridge logic on the controller side while the multiplexer channels are actively energized. Mismatched VXI resource manager driver layers can cause relay driver register timeout faults during high-speed scanning routines.

Frequently Asked Questions (FAQ)

Q: Why is this New Surplus unit priced higher than refurbished modules online?

A: Refurbished modules are pulled from retired machinery and often suffer from high contact resistance, thermal degradation, and relay wear. Our New Surplus units come directly from controlled original storage, feature zero contact wear, and carry a full replacement warranty. Paying a slight premium for genuine new hardware avoids thousands of dollars in emergency troubleshooting and lost test throughput.

Q: Are these units truly factory-new and unused?

A: Yes. This product is a Brand New Surplus unit. It is not used, not pulled from a decommissioned plant, and not refurbished. Modules are held in original anti-static packaging, opened only under ESD-controlled conditions for visual inspection and functional backplane testing.

Q: Is the Keysight officially obsolete (EOL)?

A: Yes, Keysight has discontinued production of the VXI platform. Because OEM support is limited, holding 1-2 New Surplus units as critical buffer stock is recommended to prevent indefinite line stoppages.

Q: Can I hot-swap the card while the VXI chassis is powered on?

A: No. Hot-swapping register-based VXI cards can damage the P1/P2 backplane connector pins and cause electrical transients that destroy onboard CMOS logic. Always shut off mainframe power before insertion or extraction.

Q: Will replacing my unit cause memory loss or require reprogramming?

A: No programming logic is stored on the card itself. All routing logic is managed by your external VXI system controller via SCPI commands. As long as you replicate the hardware jumper configuration on the terminal block, the replacement card operates seamlessly without software modifications.

Q: What warranty coverage is included with this product?

A: All our New Surplus Keysight modules include a comprehensive 1-year functional replacement warranty and complete QC inspection reports verifying register access and relay continuity.
