Test Method for Second Harmonic Distortion of Passives Using a Single Carrier

The purpose of this document is to establish the standard methodology to measure second harmonic distortion in a Cable Telecommunication System passive at high signal level conditions (50 - 60 dBmV). Due to the difficulty in acquiring multi-carrier signal generators with both 55 dBmV output and intermod beats at -120 dBc, the test procedure will use a single carrier source test method.
