Section 2—7613/R7613 Service
CALIBRATION
Calibration Interval
To assure instrument accuracy, check the calibration of
the 7613 every 1000 hours of operation, or every six
months if used infrequently. Before complete calibration,
thoroughly clean and inspect this instrument as outlined in
the Maintenance section.
TEKTRONIX Field Service
Tektronix, Inc. provides complete instrument repair and
recalibration at local Field Service Centers and the Factory
Service Center. Contact your local TEKTRONIX Field
Office or representative for further information.
Using This Procedure
General. This section provides several features to facili-
tate calibration of the 7613. These are:
index. An index is given preceding the calibration
procedure to aid in locating a step.
Partial Procedure. A partial calibration is often desirable
after replacing components, or to touch up the adjustment
of a portion of the instrument between major recalibra-
tions. To calibrate only part of the instrument, set the
controls as given under Preliminary Control Settings and
start with the nearest Equipment Required list preceding
the desired portion. To prevent unnecessary recalibration of
other parts of the instrument, re-adjust only if the tolerance
given in the CHECK- part of the step is not met. If
re-adjustment is necessary, also check the calibration of any
steps listed in the INTERACTION- part of the step.
Complete Calibration Procedure. Completion of each
step in the following calibration procedure insures that this
instrument is both correctly adjusted and performing
within all given tolerances.
IMPORTANT NOTE
All waveforms shown in this section were taken with
a TEKTRONIX Oscilloscope Camera System, unless
noted atherwise.
TEST EQUIPMENT REQUIRED
General
The test equipment and accessories, or its equivalent,
given in the Test Equipment table is required for complete
calibration of the 7613. Specifications given for the test
equipment are the minimum necessary for accurate calibra-
tion. Therefore, the specifications of any test equipment
used must meet or exceed the listed specifications. All test
equipment is assumed to be correctly calibrated and
operating within the listed specification. Detailed operating
instructions for the test equipment are not given in this
procedure. Refer to the instruction manual for the test
equipment if more information is needed.
Special Calibration Fixtures
Special TEKTRONIX calibration fixtures are used in this
procedure only where they facilitate instrument calibration.
These special calibration fixtures are available from
Tektronix, Inc. Order by part number through your local
TEKTRONIX Field Office or representative.
Calibration Equipment Alternatives
All of the listed test equipment is required to completely
check and adjust this instrument. This Calibration
procedure is based on the first item of equipment given as
an example of applicable equipment. When other
equipment is substituted, control settings or calibration
setup may need to be altered slightly to meet the
requirements of the substitute equipment. If the exact item
of test equipment given as an example in the Test
Equipment table is not available, first check the Specifica-
tions column carefully to see if any other equipment is
available which might suffice. Then check the Usage
column to see what this item of test equipment is used for.
lf used for a check or adjustment which is of little or no
importance to your measurement requirements, the item
and corresponding step(s) can be deleted.
The following procedure is written to completely check
and adjust the 7613 to the limits given in Section. 2 of the
Operators Manual and to allow interchanging 7000-series
plug-in units between 7000-series mainframes without the
need to recalibrate the instruments each time. If the
applications for which you will use the 7613 do not require
the full available performance from the 7613/plug-in
combination, this procedure and the required equipment
list can be shortened accordingly. For example, the basic
measurement capabilities of this instrument can be verified
by checking vertical deflection accuracy, vertical
square-wave response, and basic horizontal timing with
7000-series real-time plug-in units and an accurate square
wave signal. Also, if the 7613/plug-in combination is to be
used as a fixed system without the need to interchange
plug-in units, all tests can be made by substituting vertical
plug-in units and applicable test signals for the 067-0587-01
mainframe standardizer calibration fixture.
