Advantest Q82202 – Optical Sensor Interface Unit Plug-in for the Q8221

The Advantest Q82202 is an optical sensor interface unit plug-in module for the Advantest Q8221 optical test system. It provides the interface between optical sensor heads and the Q8221 measurement mainframe, enabling precise connection and control of optical sensors for diverse measurement applications. The unit supports high-speed data transfer via USB 2.0 and operates at 5V DC, functioning as one of two possible channels within the Q8221’s modular architecture.

– Technical Specifications

Measurement accuracy reaches ±2.5% at the calibration point and ±4.5% across broad-band wavelength regions with sensitivity curve compensation. Linearity is specified as ±0.5%. Polarization dependence measures 0.003 dBp-p or less with specific optical sensors. High sensitivity sensor configurations achieve noise levels of -94 dBm. The module integrates with the Q8221 mainframe to support multiple measurement modes: absolute power, relative power, loss, return loss, and PDL (polarization dependent loss) measurement. Output units include dBm, dB, mW, and W. The system samples at up to 100 times per second with ranging speeds between 20 msec minimum and 500 msec maximum. Data recording capability stores up to 400 points per channel with external plotter output.
