Abstract
The several clock lines on a burn-in board are monitored by diode ANDing the clock lines to one or two monitor lines, the ANDing circuitry being mounted on the burn-in board and each monitor line being connected through the burn-in chamber back wall to a detection circuit for detecting presence, level, and/or other quality of the signal on the monitor line and giving an indication and sounding an alarm when the desired monitor signal quality is absent.
