Application Examples
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).

Next you want to see the pulses in the incoming digital signal, but the pulse widths vary so it is
hard to establish a stable trigger. To look at a snapshot of the digital signal, do this step:
1.
Push
Single
to capture a single acquisition.
This assumes that the oscilloscope will trigger
with the current settings.
Now you want to measure the width of each
displayed pulse. You can use measurement
gating to select a speci
fi
c pulse to measure.
To measure the second pulse:
2.
Push
