Overshoot Measurement and Math channels in PicoScope 7 An overshoot is a short term spike or transient in a waveform which rises above the Top or drops below the Base levels of a waveform. Typically an overshoot occurs at the top of a fast rising edge or at the bottom of a fast falling edge, like we see in a squarewave. An overshoot on a rising edge will typically rise for a very short time (relative to the pulse width) above the Top level then may oscillate or ‘ring’ with reducing amplitude above and below the Top level, until finally settling at the Top level. This is called a Positive overshoot. Similarly, an overshoot on a falling edge will typically fall for a very short time below the Base level then oscillate about the Base level until finally settling at the Base level. This is called a Negative overshoot.   In the article below is a demonstration of how to setup the Automated Measurement and Math channel for Overshoot.
