Performance Tests Required Test Equipment
42 Agilent 81560A, 81561A, 81566A, & 81567A Optical Attenuator Modules, First Edition
Test Record
Results of the performance test may be tabulated in the Test Record
provided at the end of the test procedures. It is recommended that you
fill out the Test Record and refer to it while doing the test. Since the
test limits and setup information are printed on the Test Record for
easy reference, the record can also be used as an abbreviated test
procedure (if you are already familiar with the test procedures). The
Test Record can also be used as a permanent record and may be
reproduced without written permission from Agilent Technologies.
Test Failure
If the Agilent 81560/61A/66A/67A Attenuator module fails any
performance test, return the instrument to the nearest Agilent
Technologies Sales/ Service Office for repair.
Instrument Specification
Specifications are the performance characteristics of the instrument
that is certified. These specifications, listed in “Specifications” on
page 29 are the performance standards or limits against which the
Agilent 81560A/61A/66A/67A can be tested.
Any changes in the specifications due to manufacturing changes,
design, or traceability to the National Institute of Standards and
Technology (NIST), will be covered in a manual change supplement, or
revised manual. Such specifications supersede any that were
previously published.
