Advantest Q8221 Two-Channel Optical Power Meter
Feature:
Two-Channel Plug-In System
Two channels of the Q8221 can be used individually or simultaneously. Seven types of optical sensors and nine types of light sources are available to accomodate diverse applications.
Ensures Accuracy Over the Entire Range of Power and Wavelength
The optical sensors for Q8221 assure high accuracy of +/-2.5% at calibration point. In broad band wavelength region, they assure +/-4.5% accuracy by compensating the sensitivity curve over wavelengths of each sensors. Further more, the linearity of +/-0.5% is assured. Not only at the calibration point, these sensors also assure at the broad band wavelength region and the level to be measured.
Three Types of High-Sensitivity Sensors Noise Level: -94 dBm
The Q82208, Q82232 and Q82233 Optical Sensors achieves high sensitivity by cooling the InGaAs photo-diode. The Q82208 especially achieves -94 dBm. High power can be measured with high linearity up to +10 dBm with all three ty
