Rise time is typically measured between the 10% and 90% amplitude levels of a signal. These are the default reference levels
that the oscilloscope uses for rise time measurements. However, in this example, you need to measure the time that the signal
takes to pass between the 0.8 V and 2.0 V levels.
You can customize the rise time measurement to measure the signal transition time between any two reference levels. You
can set each of these reference levels to a speci
fi
c percent of the signal amplitude or to a speci
fi
c level in vertical units (such
as volts or amperes).
