ABSTRACT:
A non-invasive testing system for video signals includes a jack having a monitor conductor connected across an amplification circuit to a central conductor. The amplification circuit amplifies the power of a signal drawn off of the central conductor such that the power level at the monitor conductor is substantially equal to the power level on the central conductor. When it is desired to test a power level of a signal being produced by a video source, test equipment is connected to the monitor conductor to permit non-invasive testing of the signal.
