Abstract
An interconnection module provides a normal-through connection for an electrical signal. The interconnection module includes a housing defining an input and an output, a conductor disposed within the housing provides a signal path between the input and the output, and a removable monitor module mated to the housing. The monitor module includes a monitor port and an active circuit for sensing the electrical signal and for providing to the monitor port a monitor signal indicative of the electrical signal. The active circuit is disposed electrically in parallel to the signal path and exhibits an impedance to the signal path that is sufficiently high so that the electrical signal being monitored is not disturbed by the active circuit. The monitor circuit is hot-swappable so that removal or installation of the monitor module from the housing during transmission of the electrical signal through the signal path will not disturb the electrical signal. The interconnection module can be used with digital video signals such as those conforming to the serial data interface (SDI) standard.
