Abstract : An event stacker and display device for encoding a multiplicity of event signals into a single output source. The system uses an operational amplifier having three inputs weighted in a four, two, one octal fashion. The output of the amplifier is therefore restricted to one of eight possible levels. An optical isolator is also used in the system in conjunction with a Darlington amplifier and a light emitting diode (LED) display device. The optical isolator provides isolation between test equipment and other instrumentation. The Darlington amplifier provides sufficient current to drive the LED display device and the event stacker.
