This unit
The JDSU HA9/HA1 Programmable Attenuator series delivers precise optical signal level control for communications, test and measurement, and R&D applications. These units combine wide attenuation range, high accuracy, and low insertion loss to enable critical optical performance evaluation and system calibration. Programmable via GPIB or RS232 with SCPI/HP8156A-compatible commands, the HA9/HA1 supports both local front-panel control and remote operation.
Field-proven construction ensures repeatable performance across demanding test environments.

JDS Uniphase/JDSU HA9/HA1 — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the JDS Uniphase/JDSU HA9/HA1. Calibration covers attenuation accuracy at 5 or more set values across the full range (0 to rated maximum dB), attenuation linearity, wavelength-dependent attenuation at 1310 nm, 1490 nm, and 1550 nm, insertion loss at minimum attenuation (0 dB position), and polarization-dependent loss (PDL) where applicable. All calibrations ship with a NIST-traceable certificate. Turnaround is typically 1–3 business days after receipt.
Common JDS Uniphase/JDSU HA9/HA1 faults: motor and gear mechanism wear (attenuation steps or loss of smooth control), optical port contamination, EEPROM calibration data corruption. Most common faults are motor or gear mechanism wear on variable attenuators causing attenuation steps or loss of smooth control, optical port contamination reducing dynamic range, and EEPROM calibration data corruption on digitally controlled models.
