This unit
The Keysight E1458A is a C-size VXI module providing 96 digital channels through twelve 8-bit bi-directional data ports arranged in three banks. Each port is individually configurable for positive or negative true logic and read/write or tri-state operation, supporting flexible data transmission from single or multiple ports up to 32-bit long words. The module delivers 325 kb/s block transfer rates and integrates six GPIO handshake protocols - none, leading edge, trailing edge, pulse, partial, and strobe - with dedicated FLAG, CTL, and I/O status lines per port. Three additional control lines (PIR, /RES, STS) enable custom handshaking and interrupt functions via register-based programming. TTL-compatible at 5V maximum, the E1458A suits digital subassembly testing, data acquisition, and control applications requiring high-density I/O in VXIbus systems.

Keysight / Agilent / HP E1458A — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Keysight / Agilent / HP E1458A. 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 Keysight / Agilent / HP E1458A 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.
