Advantest TQ82014

The Advantest TQ82014 is a single-channel optical power sensor designed as a plug-in accessory for Advantest optical power meters and spectrum analyzers. It extends measurement capability across the visible and near-infrared spectrum, enabling precise optical power characterization in telecommunications, laser printing, optical storage, and R&D environments. The sensor employs a silicon photodiode with onboard wavelength sensitivity compensation, delivering direct absolute power readings with 0.01 dB resolution across a dynamic range spanning six decades.

Compatibility & Integration The TQ82014 connects directly to Advantest TQ8210, TQ8215, Q8214A, and Q8210 optical power meters, as well as select Advantest spectrum analyzers. Wavelength sensitivity at 400 nm may degrade under high-humidity conditions; use in other bands is unaffected by ambient moisture.
