HP / Agilent 81536A — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the HP / Agilent 81536A. Calibration covers detector responsivity across all specified wavelengths (typically 800-1700 nm range), absolute power accuracy, and EEPROM calibration coefficient update. Compatible with Agilent/HP 8163A/B, 8164A/B, and 8166A/B mainframes.. All calibrations ship with a NIST-traceable certificate. Turnaround is typically 1–3 business days after receipt.
Common HP / Agilent 81536A faults: FC/PC connector damage, EEPROM failure (mainframe shows unrecognized sensor), reduced responsivity. Common faults include FC/PC input connector damage, EEPROM failure causing the module to appear unrecognized by the mainframe, and reduced detector responsivity from contamination.
