ABSTRACT:
A system, method, and apparatus for obtaining a record of logic level transitions within a signal, and for accurately determining a voltage-time pair exhibited by the signal. To achieve these ends, a front-end device may be mated to a real-time sampling system, such as an oscilloscope. The front-end device effectively permits the oscilloscope to observe signals exhibiting greater data rates than otherwise possible without the front-end device.
