NOTE.
The Positive Width measurement is available as an automatic measurement
in the Measure Menu. (See page 86, Taking Measurements.)
Measuring Rise Time
After measuring the pulse width, you decide that you need to check the rise time
of the pulse. Typically, you measure rise time between the 10% and 90% levels of
the waveform. To measure the rise time, follow these steps:
1.
Turn the
Horizontal Scale
(seconds/division) knob to display the rising edge
of the waveform.
2.
Turn the
Vertical Scale
(volts/division) and
Vertical Position
knobs to set
the waveform amplitude to about
fi
ve divisions.
3.
Push the
1
(channel 1 menu) button.
4.
Push
Volts/Div
►
Fine.
5.
Turn the
Vertical Scale
(volts/division) knob to set the waveform amplitude
to exactly
fi
ve divisions.
6.
Turn the
Vertical Position
knob to center the waveform; position the baseline
of the waveform 2.5 divisions below the center graticule.
7.
Push the
Cursor
button to see the Cursor Menu.
8.
Push the
Type
side-menu button. A pop-out menu should appear showing a
scroll-able list of the available cursor types.
