Test and Measurement

The complete, practical guide to testing fiber optic communication components and systems. Fiber optic networks are evolving rapidly--and so is the technology used to design, measure, and test them. "Fiber Optic Test and Measurement" is the first authoritative, complete guide to measuring both current optical networks and those on the horizon. It reflects the collective experience of Hewlett-Packard's world-class lightwave test and measurement organization, and presents extensive information that has had limited circulation to date. Learn how to characterize all three basic components of a fiber optic communication system: the optical transmitter, fiber medium, and optical receiver. Review each fundamental area of fiber optic measurement, including: Optical power measurements using several types of photodetectors Spectral measurements using diffraction gratings, Michelson interferometers and both heterodyne and homodyne spectrum analysis Polarization measurements--increasingly important in high data rate networks that utilize optical amplifiers Modulation measurements via frequency and time domain analyses The book's unprecedented coverage of advanced fiber technology will be invaluable to professionals implementing or maintaining new optical networks. Learn how to: Test digital fiber systems to SONET/SDH international standards Accurately characterize the behavior of Wavelength Division Multiplexing (WDM) fiber systems Test two-port optical devices for insertion loss, reflectivity of components, chromatic and polarization mode dispersion, and the behavior of Erbium-doped fiber amplifiers (EDFAs). This practical guide will help technicians, engineers, and scientistsaccurately measure and test fiber optic systems, without becoming experts in fiber optic theory. It will be equally useful for experienced fiber optic professionals and those new to the field.

Testing designed to measure cognitive abilities and performance, and the debate over the fairness, effectiveness, and proper use of that testing continue. Few professionals, however, would dispute the need for some form of standardized testing in education, industry, the military, and healthrelated fields. The controversy over the flaws, both alleged and recognized, of aptitude and achievement tests should serve not as a rallying cry for the elimination of these instruments but as a challenge to construct more accurate assessment tools and methods of administering and using them fairly and objectively. This book is designed to assist in that effort. Tests and Examinations is the third volume in Lewis Aiken’ s popular series on psychometric assessment. Unlike its critically acclaimed predecessors— Rating Scales and Checklists and Questionnaires and Inventories, which are mainly devoted to the assessment of affective and social variables— the present volume focuses on the measurement of cognitiv and psychomotor abilities. While Dr. Aiken provides ample coverage of the conceptual and theoretical foundations of psychological testing, in the main, the discussion is geared toward the design and application of all types of tests in a wide range of situations. Clinicians, researchers, and students alike will appreciate the author’ s clear, step-by-step guidelines, pointers, and helpful hints on how to design, construct, administer, score, and evaluate tests of achievement, single and multiple aptitudes, intelligence, and cognitive development and disorders. Many rapid skillbuilding exercises are included at the ends of the chapters, and an enclosed computer diskette containsseveral dozen programs to provide experience in selecting, using, and evaluating tests.

Test-retest method - The test-retest method tests for the consistency of measurement based on the correlation between test and retest scores for the same individual.

Synthetic instrument - A synthetic instrument is a term in test and measurement science or metrology. It describes a functional mode or personality component of a synthetic measurement system that performs a specific synthesis or analysis function on a device under test (DUT) using specific software running on generic, non-specific physical hardware.

Nerve conduction velocity - Nerve conduction velocity (NCV) is a measurement made during a Nerve conduction study (NCS), a test commonly used to evaluate function of the motor and sensory nerves of the body. Some people use the term NCV to mean the actual test, but this is improper use of the term since velocity is only one measurement.

Inductive reasoning aptitude - Inductive reasoning is a measureable aptitude for how well a person can identify a pattern within a large amount of data. Measurement is generally done in a timed test by showing four pictures or words and asking the test taker to identify which of the pictures or words does not belong in the set.
