This unit
The Advantest TQ8214 is a portable optical power meter that delivers precise measurement of optical signal power across configurable wavelength ranges. Built for field deployment in optical communications, laser systems, and R&D environments, the instrument combines high sensitivity with broad dynamic range through interchangeable sensor modules. Its LCD display presents power in linear (W) or logarithmic (dBm) units alongside wavelength readout, while automated compensation and user-selectable functions enable stable, accurate readings in variable conditions.
