Spectracom 8143 Overview
The Model 8143 Signal Selector/ Distribution Amplifier detects failure of either input signal and provides manual or automatic switchover between two frequency sources. The selected input is distributed via twelve buffered output line drivers.
In the automatic mode, Channel A is selected when it is present. Switchover occurs when Channel A is removed, when an alarm is sensed, or when a manual selection is made. In manual mode, switchover is operator-controlled.
