1.
Set
the A TIME/DIV switch
to
a setting
that
displays
all
of
the rising edge
of
the
waveform.
2. Adjust
the
VOL TS/DIV and VAR VOL TS/DIV
controls
to
display signal amplitude
of
exactly five
divisions.
3.
Vertically position the trace so
that
the
zero
reference
of
the
waveform just touches the
0%
graticule line and
the
top
of
the
waveform touches
the 100% graticule line (see Figure 31
).
4. Adjust
the
DELAY TIME POSITION control
to
move
the reference
point
to
the
1
0%
graticule line (see
Figure
31,
Point
A).
5. Adjust
the
t. TIME control
to
move
the
time
measurement
point
to
the
90% graticule line (see
Figure 31, Point
B).
6. Read
the
rise time on
the
DM44 Readout.
