PERFORMANCE
CHECK
Introduction
This
section
of
the
manual
provides
a
procedure
for
rapidly
checking
the
performance
of
the
Type
3B5.
This
procedure
checks the operation
of
the
instrument
without
making
internal
adjustments. However, screwdriver
adjust
ments
which
are
located
on
the
front
panel are
adjusted
in
this
procedure.
If
the
instrument
does
not
meet
the
performance
require
ments
given
in
this procedure,
internal
checks
and/or
adjust
ments
are
required.
See
the Calibration
section.
All
per
formance
requirements
given
in
this
section
correspond
to
those
given
in
the
Characteristics
section.
NOTE
All
waveforms
shown in
this
section
are
actual
waveform
photographs
taken
with
a
Tektronix
Oscilloscope
Camera System
and
Projected
Grati
cule.
