TEST
EQUIPMENT REQUIRED
The
test
equipment
listed
in
Table 5-2
is
required
for
a
complete Adjustment and Performance
Check
of
the
instrument.
If
only
a
Performance Check
is
to
be
performed, the items required
for
Adjustment
are not
required,
and
are indicated by footnote
1.
The
remaining
test
equipment
is
common
to
both procedures.
The
specifications for test
equipment, given
in
Table 5-2,
are the
minimum
required
to
meet
the Performance
Requirements. Detailed operating instructions
for test
equipment are omitted
in
these procedures. Refer
to
the
test
equipment
instruction
manual
if
more
information
is
needed.
SPECIAL FIXTURES
Special
fixtures
are
used
only
where
they
facilitate
instrument adjustment.
These
fixtures
are available
from
Tektronix,
Inc.
Order
by part
number
from Tektronix
Field
Offices or
representatives.
TEST
EQUIPMENT ALTERNATIVES
All of
the
listed
test
equipment
is
required
to
completely
calibrate this
instrument.
However, complete
checking
or
calibration
may
not
always be necessary
or desirable.
You
may
be
satisfied
with checking
only selected
characteristics,
thereby reducing the
amount
of test
equipment
actually required.
The
calibration
procedures
are
based on the
first
item
of
equipment given as
an example.
When
other equipment
is
substituted, control settings or
setups
may
need
to
be
altered.
If
the exact item
of
equipment
given as
an
example
in
Table 5-2
is
not
available,
first
check
the
specifications
column
carefully to
see
if
any
other
equipment might
suffice.
Then
check the Purpose
column
to
see
what
this
item
is
used
for.
If
used
for a
check
or
adjustment
that
is
of
little
or
no importance
for
your
measurement
requirements, the item
and corresponding
step(s)
can be
deleted.
