Abstract
A digital engine analyzer includes an ADC which can become railed to clip an acquired waveform signal. The analyzer has a waveform display system which displays an indication of the rail level and the fact that a displayed waveform representation is clipped at the rail level. In one embodiment the rail level is displayed as a red line and the clipped portion of the waveform is displayed as a flat line substantially at the rail level. In another embodiment, the clipped portion of the waveform representation is displayed in red as a horizontal line at the rail level while the remainder of the waveform representation is displayed in green, and the rail level is otherwise not displayed.
