Tektronix 2230 Service Manual

Maintenance—2230 Service
CORRECTIVE MAINTENANCE
INTRODUCTION
Corrective maintenance consists of component replace
ment and instrument repair. This part of the manual
describes special techniques and procedures required to
replace components in this instrument. If it is necessary to
ship your instrument to a Tektronix Service Center for
repair or service, refer to the “ Repackaging” information
in Section 2 of this manual.
MAINTENANCE PRECAUTIONS
To reduce the possibility of personal injury or instru
ment damage, observe the following precautions.
1. Disconnect the instrument from the ac-power source
before removing or installing components.
2. Verify that the line-rectifier filter capacitors are
discharged prior to performing any servicing.
3. Use care not to interconnect instrument grounds
which may be at different potentials (cross grounding).
4. When soldering on circuit boards or small insulated
wires, use only a 15-watt, pencil-type soldering iron.
OBTAINING REPLACEMENT PARTS
Most electrical and mechanical parts can be obtained
through your local Tektronix Field Office or representative.
However, many of the standard electronic components can
usually be obtained from a local commercial source.
Before purchasing or ordering a part from a source other
than Tektronix, Inc., please check the “ Replaceable Elec
trical Parts” list for the proper value, rating, tolerance, and
description.
NOTE
Physical size and shape of a component may affect
instrument performance, particularly at high frequen
cies. Always use direct-replacement components,
unless it is known that a substitute will not degrade
instrument performance.
Special Parts
In addition to the standard electronic components,
some special parts are used in the instrument. These com
ponents are manufactured or selected by Tektronix, Inc. to
meet specific performance requirements, or are manufac
tured for Tektronix, Inc. in accordance with our
specifications. The various manufacturers can be identified
by referring to the "Cross Index-Manufacturer’s Code
number to Manufacturer" at the beginning of the
“ Replaceable Electrical Parts” list. Most of the mechanical
parts used in this instrument were manufactured by
Tektronix, Inc. Order all special parts directly from your
local Tektronix Field Office or representative.
Ordering Parts
When ordering replacement parts from Tektronix, Inc.,
be sure to include all of the following information:
1. Instrument type (include all modification and option
numbers).
2. Instrument serial number.
3. A description of the part (if electrical, include its full
circuit component number).
4. Tektronix part number.
Selectable Components
Several components in the instrument are selectable to
obtain optimum circuit operation. Value selection of these
components is done during the initial factory adjustment
procedure. Usually, further selection is not necessary for
subsequent adjustments unless a component has been
changed that affects circuitry for which a selected com
ponent has been specifically chosen.
MAINTENANCE AIDS
The maintenance aids listed in Table 6-24 include items
required for performing most of the maintenance pro
cedures in this instrument. Equivalent products may be
substituted for those given, provided their characteristics
are similar.
