h.
Using
the
HORIZONTAL
POSITION
and
VERNIER
con
trols,
position
the
leading
edge
of
the
pulse
to
the
center
of
the
graticule.
i.
Turn
the
SWEEP
MAGNIFIER
to
X10
.
This
gives
an
equivalent
time/cm
of
10
nanoseconds.
j.
Measure
the risetime between the
10%
and
90% points
on
the
waveform
(see
Fig.
4
19).
k.
Using
the
HORIZONTAL POSITION
and
VERNIER
con
trols,
position
the
trailing
edge
of
the
pulse
to
the
center
of
the
graticule
and
measure
the
falltime
.
I.
Set
the
AMPLITUDE
switch
to
—
3
to
10
V
and
repeat
h,
i,
i,
and
k.
NOTE
The
risetime
or falltime
of
the
Type
114
as
read
on
the
crt
of
the Type
547
will be
less
than
13
nanoseconds.
The
50
megacycle
bandpass
of
the
Type
547
/
1
A1
adds
about
25%
to the
actual
rise
and
fall
times
of
the
Type 114.
For
this
reason,
risetime
and
f
a
lltime
should
be checked
with
a
sampling
oscilloscope
system
if
one
is
available.
