This unit
The Agilent/Keysight E8460A is a C-size, 1-slot VXI relay multiplexer delivering 256 channels of fast-action reed relay switching for automated test systems requiring high-density signal routing. Register-based control enables programmable topology configurations from 256×1 to sixteen 16×1 arrangements, supporting two-wire, three-wire, and four-wire measurement setups. Contact protection and minimal crosstalk preserve signal integrity across switching operations.

Terminal Block Options Three terminal block configurations available (ordered separately):
Option 012: Crimp-and-insert connectors. Connector blocks require replacement after 10,000 hours when switching voltages exceed 60 V DC, 50 V ACrms, or 70.7 V ACpeak.
Option 014: Fault Tolerant Terminal Block with nine ribbon-cable headers and channel-integrated PTC resettable fuses. Maximum voltage: 60 V DC, 50 V ACrms, or 70.7 V ACpeak.
Option 015: Ribbon Cable Connector Terminal Block with nine ribbon-cable headers.
Compatibility & Integration Analog bus connectivity enables daisy-chaining with additional E8460A modules or compatible measurement modules such as the E1411B. Standard analog bus cable E1400-61605 provides interconnection.

Agilent / Keysight E8460A — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Agilent / Keysight E8460A. Calibration covers all module-specific parameters per manufacturer datasheet, output accuracy and linearity, frequency accuracy, and VXI register and trigger bus compliance. All calibrations ship with a NIST-traceable certificate. Turnaround is typically 1–3 business days after receipt.
Common Agilent / Keysight E8460A faults: relay contact wear, DAC/ADC drift, VXI backplane connector oxidation. Common faults include relay contact wear, DAC or ADC gain drift, and VXI backplane edge connector oxidation. Most modules are repaired at the component level with full post-repair verification in a C-size or D-size mainframe.
