On some tektronixs Oscillscopes , they have a Ratio mode for cursors to measure the Ratio of a waveform. It's says in the tektronix manual 2467 that you can measure two outputs and compare the Ratio of the voltages and Time ratio. What kind of circuits would I want to measure the Ratio of voltages and time durations? The only time i have used the Ratio cursors is when I'm measure the AM amplitude Modulations of an RF carrier. Can you guys please think of other use of using the Ratio cursors?
