Oscilloscope math functions aid circuit analysis

摘要

Most engineering labs have digital oscilloscopes, but many engineers don't fully explore their features. Among the more interesting features of a digital oscilloscope is its math channel, which can help you analyze hot'swap and load-switching circuits. Math functions can yield detailed information about hot-swap-circuit parameters that can aid you in design and troubleshooting. For example, you can use an oscilloscope's math functions to calculate load capacitance, which can reveal a MOSFET's transient-power dissipation during start-up or shutdown.
