Specification and Performance Check-5110
PERFORMANCE CHECK
Introduction
This procedure checks the oscilloscope for measure­
ment accuracy against the tolerances listed as Perfor­
mance Requirements that appear under Electrical
Characteristics at the beginning of this section. If the
instrument fails to meet the requirements given in this
Performance Check, the Adjustment procedure (Section 3
in this manual) should be performed. The Performance
Check can be used by an incoming inspection facility to
determine acceptability of performance. It is not
necessary to
remove the instrument cabinet to perform
this procedure, since all checks are made from the front
panel.
The Electrical Characteristics in this section are valid
only if the oscilloscope has been calibrated at an ambient
temperature b20° C to +30° C and is operating at
an ambient temperature between 0°C to +50° C.
PERFORMANCE CHECK INTERVAL
To ensure instrument accuracy, check the perfor­
mance of the oscilloscope every 1000 hours of operation,
or every 6 months if used infrequently.
TEST EQUIPMENT REQUIRED
The following test equipment, orequivalent, is required
to perform a performance check of the oscilloscope. The
test equipment performance requirements listed are the
minimum required to verify the performance of the
equipment under test. Substitute equipment must meet or
exceed the stated requirements. All test equipment is
assumed
to be operating within tolerance.
Tolerances that are specified in this Performance
Check procedure apply to the instrument under test and
do not include test equipment error. Limits and tolerances
in this procedure are instrument performance re­
quirements only if listed in a Performance Requirements
column
that appears under Electrical Characteristics at
the beginning of this section; information given in the
Supplemental Information column is provided for user
information only, and should not be interpreted as perfor­
mance requirements.
SPECIAL TEST EQUIPMENT
Special test equipment is used where necessary to
facilitate the procedure. Most of this equipment is
available from Tektronix, Inc. and can be ordered through
your local Tektronix Field Office or representative.
