JDS Uniphase JDSU HA9 HA97E+10KSU1 Programmable Attenuator

The JDS Uniphase JDSU HA9 HA97E+10KSU1 is a programmable optical attenuator delivering precise, remote-controlled attenuation across a 100 dB range with 0.01 dB resolution. Built for laboratory testing, calibration, and R&D environments in optical communications, this singlemode device combines high accuracy (±0.1 dB) with exceptional repeatability (±0.005 dB typical) and fast switching times. SCPI/HP8156A command compatibility and dual remote interfaces enable seamless integration into automated test systems.
