Abstract:
A signal monitoring system, comprising:(a) a plurality of signal amplifiers; (b) a plurality of switching devices, wherein each one of the plurality of switching devices is connected to an input of a one of the plurality of signal amplifiers, each of the plurality of switching devices being responsive to a switching device control signal to control the switching device to prevent a signal from being applied to the input of a corresponding signal amplifier or to allow application of a signal to the input of the corresponding signal amplifier, each switching device and its corresponding signal amplifier forming a signal channel; (c) a channel disconnect selection user interface to allow a user to indicate selected ones of the signal channels; (d) a channel disconnect user interface selectable by a user; and (e) a processor connected to the plurality of switching devices and adapted to provide the switching device control signal to control the switching devices in each channel selected using the channel disconnect selection user interface to prevent a signal from being applied to the input of the corresponding amplifiers only in such selected channels when the channel disconnect user interface is selected and to provide the switching device control signal to control the switching devices in the selected channels to allow application of a signal to the input of the corresponding amplifiers in such selected channels when the channel disconnect user interface is deselected.
