Keysight E1412A C-Size VXI Digital Multimeter Module

Description

Key Technical Specifications

Product Introduction & Supply Chain Strategy

The Keysight E1412A is a C-size, 1-slot VXIbus 6.5-digit multimeter engineered for automated test equipment (ATE) environments in aerospace, defense, and telecommunications manufacturing. It provides laboratory-grade DCV, ACV, 2-wire/4-wire resistance, frequency, period, and current measurements directly over the VXI backplane. Designed for high-speed automated data acquisition, it delivers fast measurement throughput with tightly synchronized TTL triggering across system switches and digitizers.

Securing the Keysight E1412A as New Surplus is a critical supply chain safeguard for automated test systems. Because the VXI standard has reached mature/legacy status and original manufacturing lines are phased out, procuring verified factory-new modules avoids multi-month defense contract disruptions. Second-hand or refurbished VXI cards frequently suffer from relay contact wear, drifted internal voltage references, and degraded input protection diodes caused by previous over-voltage events. A single false reading from a degraded refurbished DMM can invalidate entire ATE test runs or misclassify flight-critical hardware. Stocking 1–2 units of genuine New Surplus inventory preserves original factory calibration parameters, maintains 100% signal path integrity, and ensures zero downtime during scheduled maintenance cycles.

Installation & Configuration Guide

Stage 1: Pre-Installation (Prep & Safety)

1. Power down the VXI chassis completely and disconnect main AC power. Follow standard Lock-out/Tag-out (LOTO) protocols.
2. Put on an ESD-grounded wrist strap connected to the chassis frame before touching the E1412A circuit board.
3. Record the Logical Address DIP switch settings and VXI bus interrupt levels from the module being replaced.

Stage 2: Removal

1. Unplug front-panel BNC trigger cables and terminal input connectors.
2. Loosen the top and bottom captive retaining screws on the E1412A front faceplate using a flathead screwdriver.
3. Grasp the module extraction handles firmly and pull the card straight out to disengage it from the DIN backplane connectors without bending pins.

Stage 3: Installation (Clone & Seat)

1. Configure the Logical Address DIP switch on the new E1412A to match the address of the old unit (default factory setting is usually 24).
2. Align the module card edges with the top and bottom chassis card guides in the designated C-size slot.
3. Slide the card smoothly into the slot until the backplane connectors touch, then press the extraction levers inward to firmly seat the card. Tighten the top and bottom faceplate screws.

Stage 4: Power-On & Testing

1. Apply power to the VXI mainframe and check the front-panel status LEDs. The Failed LED should illuminate briefly during self-test and extinguish once initialization passes.
2. Send a *TST? command via your VXI slot 0 controller (such as VISA or SICL) to run the internal hardware diagnostic suite.
3. Connect a precision voltage calibrator to the front input terminals and execute a baseline 10 V DC reading to confirm measurement accuracy before releasing the system to production.

Firmware/Software Versions & Upgrade Notes

• Firmware Lineage: The E1412A uses internal ROM-based firmware designed for SCPI command processing. Board revisions specify hardware compatibility for register-level programming versus high-level driver abstraction (VISA/IVIs).
• Driver & OS Compatibility: Compatible with Agilent/Keysight IO Libraries Suite, NI-VISA, and legacy HP-IB/VXI controllers. Ensure your host system driver supports SCPI command set translation over the P1/P2 VXI backplane.
• Upgrade/Swap Warning: Never attempt field-flashing of system ROMs or swap daughterboards between different assembly revisions. Altering internal EEPROM calibration constants without a reference precision source like a Fluke 5720A will permanently degrade measurement accuracy. Always swap the instrument as a complete, factory-verified card assembly.

Frequently Asked Questions (FAQ)

Q: Is this Keysight unit genuine New Surplus or a refurbished card?

This module is 100% Brand New Surplus inventory. It has never been installed in a test rack, never fielded on a test line, and never repaired. It remains in original anti-static protective packaging, opened strictly for visual inspection and initial QC power-on verification.

Q: Why choose New Surplus over lower-cost refurbished VXI modules available online?

Refurbished VXI modules carry high risk in mission-critical ATE applications. Prior thermal stress, relay contact pitting, and aging input protection components can introduce intermittent measurement drift that is difficult to diagnose. Purchasing New Surplus ensures zero component degradation, factory-level reliability, and full peace of mind for critical test operations.

Q: How does purchasing New Surplus impact Total Cost of Ownership (TCO)?

While refurbished cards appear cheaper up front, a failed DMM in an automated test cell can halt an entire production line or reject valid aerospace assemblies. Paying a modest premium for New Surplus eliminates emergency line stoppages, re-calibration cycles, and expensive re-testing of false failures, providing a vastly superior long-term ROI.

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

No. Hot-swapping is strictly prohibited in VXIbus architectures. Inserting or removing the while the backplane is energized will cause bus errors, disrupt active backplane communication, and potentially damage the DIN connector pins or backplane transceivers. Always shut down mainframe power before module insertion or removal.

Q: What documentation and quality verification accompany this unit?

Each module ships with its original serial number label intact, pristine backplane pin condition, and a comprehensive QC verification report confirming self-test pass status and visual inspection clearance.

Q: What warranty is provided with this New Surplus card?

We cover this module with a full 1-year functional replacement warranty from the delivery date. If the hardware experiences any functional defect under standard operating conditions within 12 months, we provide a direct replacement unit or a full refund.
