Abstract
This invention is a method (and an apparatus in combination) for sweep testing of cable television distribution systems and the like, wherein time division multiplexing between test signal and program signal is accomplished in such manner as to eliminate interference to the program signal due to testing. Additionally, the test signal received by the detector is time demultiplexed in such manner that the test signal is displayed clearly without interfering signals.
