K Set the oscilloscope to display 2 complete cycles
with
the
peaks
of
the
square
wave at the
0070
and
100070
graticule lines.
Procedure:
A.
Preset
the
3314A.
C
Connect
the
50
Ohm
Feedthrough
Termination to
the
3314A's
Main
Output.
Connect
the 5000 Feed-
through
Termination
to the 3314A's X3
Output.
D, Measure
the
DC voltage at
the
X3
Output.
This
voltage
should
be within 40mV
of
OVDC.
F. Using the oscilloscope's delay function (set
the
delayed time per division
to,
IIlS/DIV). measure
the
rise
and
fall time from
the
10070
to
90070
graticule lines. In
both
cases. this
should
be less
than
~
divisions
(
<100ns).
