This unit
The Advantest Q8221 is a two-channel optical power meter designed for precise measurement and analysis of optical power across diverse applications. Its flexible plug-in system accommodates different optical sensors and light sources, enabling absolute power, relative power, loss, and return loss measurements. The instrument delivers high accuracy with ±2.5% performance at the calibration point and ±4.5% across the broadband wavelength region when using sensitivity curve compensation.
A 5-1/2 digit display presents measurements in watts (mW, µW, nW, pW), dBm, or dB with 0.001 dB resolution on the display panel and 0.0001 dB via GPIB data output.
