Abstract: Tuners are adapted to accept a received signal input and provide both a desired tuner output and the received signal as an output. Accordingly, a single tuner circuit, preferably an integrated circuit, may be cascaded to provide a multiple tuner configuration. Any number of such integrated circuit tuners may be cascaded together for a multiple tuner application. Alternative embodiments provide a multiple tuner adapter for cascading devices.

Abstract: Systems and methods which implement calibration for signal errors in a communication network, such as non-uniform frequency response, are disclosed. According to a preferred embodiment of the invention, a calibration signal is communicated through the network and a receiver at a subscriber premises operates to calibrate the received signal for any tilt introduced in the signal path between the source of the signal and the subscriber premises. Preferred embodiments of the present invention provide for monitoring of the performance of signal correction components, such as by providing a feedback path from the receiver. Monitoring of calibration performance may be utilized according to preferred embodiments for developing a more full understanding of the operation of the network, identify sources of network problems, and even predict system degradation and take appropriate action before service interruption results.
