The Advantest TQ8210 is a portable, handheld optical power meter for optical communications, laser printer maintenance, CD player diagnostics, and opto-magnetic disk R&D. It delivers 0.005% to 0.1% resolution in watts and 0.01% resolution in dBm, with ±0.2% absolute A/D converter accuracy including sensor measurement error. The instrument features automatic wavelength sensitivity compensation, dual display modes (linear watts and logarithmic dBm), auto or manual range switching, and measurement speeds of 2 measurements/s or faster.
