This unit
The Agilent/Keysight E8491A is an IEEE-1394 (FireWire) to VXI interface module that bridges a PC's IEEE-1394 bus with a VXI mainframe. Housed in a C-size, single-slot form factor, it functions as a message-based commander and Resource Manager, residing in Slot 0 of the VXI mainframe. The E8491A enables data block transfers between PC and VXI systems, supporting control and data acquisition from VXI instruments across multiple mainframes.
Up to 16 VXI mainframes can be managed from a single PC via daisy-chain or star configuration. Hot-plugging capability simplifies system reconfiguration without powering down.

Agilent / Keysight E8491A — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Agilent / Keysight E8491A. 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 E8491A 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.
