Frequency Response Measurement of Digital Communications Analyzer Plug-in Modules
It has been extremely difficult to characterize the SONET/SDH standard receiver with tolerances of "0.3 dB. This paper describes a method for calibrating photoreceiver frequency response with the low inherent uncertainty of the U.S. National Institute of Standards and Technology Nd:YAG heterodyne system and transferring this calibration to a production test system while maintaining a low uncertainty
