The white paper "KNOWING THE -3dB POINT IS NOT ENOUGH" explains the significance of bandwidth performance with regard to the interconnections of video sources and destinations in systems requiring throughput of the third harmonic.
Our lab test data clearly demonstrate why a -3dB matrix bandpass specification is inadequate for determining those system frequency requirements.
To support accurate calculations required for today's highest quality video systems, AutoPatch provides the more complete +/-3dB specification.
