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?

 

You are like the chap who inquired of Michael Faraday having just witnessed a demonstration of electricity: "For what purpose would you use it?"

If you cannot imagine a usage then you don't need it!
