Appendix A — Test Records
A-1 Introduction
This appendix provides tables for recording the results of the performance verification tests (Chapter 3) and
the calibration procedures (Chapter 4). They jointly provide the means for maintaining an accurate and
complete record of instrument performance.
Some test records are customized to cover particular ML248xA, ML248xB and ML249xA options. These
records contain references to frequency parameters and power levels that are applicable to the instrument with
that option. When a test record is customized, it is labeled with the specific option that it covers. Test records
which are not customized do not specify an option list.
A-2 Measurement Uncertainty
All test records are provided with a measurement uncertainty, which consists of the type-B
1
components. The
error contributions are measurement method, test equipment, standards, and other correction factors (for
example, calibration factors and mismatch error) per the prescribed test procedure. The statement(s) of
compliance with specification
2
is based on a 95 % coverage probability for the expanded uncertainty of the
measurement results on which the decision of compliance is based. Other values of coverage probability for the
expanded uncertainty may be reported, where practicable, for some of the measured values it is not possible to
make a statement of compliance with specification
2
.
A-3 Test Records
We recommend that you make a copy of the test record pages each time a test procedure is performed.
By dating each test record copy, a detailed history of the instrument’s performance can be accumulated.
