This unit
The Agilent/Keysight E8491B is a C-size, 1-slot message-based VXI module that establishes direct PC-to-mainframe connectivity via IEEE-1394 (FireWire) bus. Designed as a high-speed controller for data acquisition involving large block transfers, the E8491B integrates Resource Manager and Slot 0 capabilities and operates as the mainframe's primary resource manager. The module leverages small differential signals (200 mV) transmitted over controlled-impedance twisted-pair wiring, delivering high-noise immunity and sustained data transfer rates to 14 MB/sec (16-bit and 32-bit modes) with backplane burst rates reaching 53 MB/sec (64-bit).
Communication occurs via IEEE-1394.1995 at up to 400 Mbits/second, supporting SCPI (32-bit I-SCPI) and SICL/VISA I/O libraries.

Agilent / Keysight E8491B — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Agilent / Keysight E8491B. 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 E8491B 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.
