DEFINITIONS3.1 Definitions of terms used in this standard. The following defini-tionsshall apply to the terms stated.3.1.1 Absolute error. The mag
24、nitude of the error without regard toalgebraic sign.3.1.2 Absolute measurement. The measurement in which the comparison isdirectly with quantities whose units are basic units of the system. Notes: (a)For example, the measurement of speed by measurements of distance and time is anabsolute measurement
25、, but the measurement of speed by a speedometer is not anabsolute measurement. (b) The word absolute implies nothing about precision oraccuracy.3.1.3 Accelerated life test. A test in which certain factors, such asvoltage, temperature, and so forth, are increased or decreased beyond normaloperating v
26、alues to obtain observable deterioration in reasonable period of time,and thereby afford some measure of the probable life under normal operatingconditions or some measure of the durability of the equipment when exposed to thefactors being aggravated.3.1.4 Acceptance test. Aoperating in accordance w
27、ith the3.1.5 Accessory. (1) Antest to verify if the unit under test (UUT) isoperational specifications.accessory is an assembly of a group of parts or aunit which is not always required for the operation of a test set or unit asoriginally designed but serves to extend the functions or capabilities o
28、f the testset; similarly as headphones for a radio set supplied with a loud-speaker, avibrator power unit for use with a set having a built-in power supply, or a remotecontrol unit for use with a set having integral controls. (2) A part, subassembly,or assembly designed for use in conjunction with o
29、r to supplement another assembly,or a unit or set, contributing to the effectiveness thereof without extending orvarying the basic function of the assembly or set. An accessory may be used fortesting, adjusting, or cali-brating purposes. (Examples: test instrument,recording camera for radar set, hea
30、dphones, emergency power supply).3.1.6 Accuracy. (1) The quality of freedom from mistake or error, that is,of conformity to truth or to a rule. Notes: (a) Accuracy is distinguished fromprecision as in the following example: A six-place table is more precise than afour-place table. However, if there
31、are errors in the six-place table, it may bemore or less accurate than the four-place table. (b) The accuracy of an indicatedor recorded value is expressed by the ratio of the error of the indicated value tothe true value. It is usually expressed in percent. Since the true value cannotbe determined
32、exactly, the measured or calculated value of highest availableaccuracy is taken to be the true value or reference value. Hence, when a meter iscalibrated in a given echelon, the measurement made on a meter of a higher-accuracy2Provided by IHSNot for ResaleNo reproduction or networking permitted with
33、out license from IHS-,-,-MIL-STD-1309Dechelon usually will be used as the reference value. Comparison of resultsobtained by different measurement procedures is often useful in establishing thetrue value. (2) The degree of correctness with which a measured value agrees withthe true value.3.1.7 Accura
34、cy aumentation routine. Test routines using auxiliary testequipment that is more accurate than the automatic test equipment complement, asmay be necessary when test accuracy ratios cannot be met otherwise.3.1.8 Accuracv enhancement. A process which provides accuracies beyond theindividual instrument
35、 capability by monitoring the instrument performance withanother instrument of much greater accuracy over the duration of the test, or bymeans of software algorithms.3.1.9 Accuracy rating. The accuracy classification of the instrument. Itis given as the limit, usually expressed as a percentage of fu
36、ll-scale value ofreading or of programmed value, that errors will not exceed when the instrument isused under reference conditions.3.1.10 Acquisition time. The time required for a test and measurementsystem to acquire an input signal, the minimum time needed to accurately measurethe applied input.3.
37、1.11 Active built-in-test (BIT). A type of BIT which periodicallydisrupts the prime system operation through the injection of test stimuli into thesystem. Also referred to as BIT, active,3.1.12 Active redundance. That condition where parallel back-up items areoperating simultaneously, rather than be
38、ing switched on when needed.3.1.13 Active sensor. (1) A sensor requiring a source of power other thanthe signal being measured. (2) A sensor that provides a signal by stimulating theUuT.3.1.14 Active testing. The process of determining equipment static anddynamic characteristics by performing a seri
39、es of measurements during a series ofknown operating conditions. Active testing may require an interruption of normalequipment operations and it involves measurements made over the range of equipmentoperation.3.1.15 Adauter. (1) A device for connecting parts that will not mate. Anaccessory to conver
40、t a device to a new or modified use. (2) A device or series ofdevices designed to provide a compatible connection between the unit under test andthe test equipment. May include proper stimuli or loads not contained in the testequipment.3.1.16 Adater kit. A kit containing an assortment of cables and
41、adaptersfor use with test or support equipment.3.1.17 Adiust. Change the value of some element of the mechanism, or thecircuit of the instrument or of an auxiliary device, to bring the indication to a3Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-M
42、IL-STD-1309Ddesired value, within a specified tolerance for a particular value of the quantitymeasured.3.1.18 Adjustment. Changing (by electronic, electrical or physical means) avariable in an item to cause a change in its output characteristics.3.1.19 Alorithmicallv jzeneratedpattern. An array of d
43、igital data auto-matically generated by a predetermined software routine or program. The patternmay be generated and applied in real time.3.1.20 Alim. To adjust a circuit, equipment or system so that their func-tions are properly synchronized or their relative positions properly oriented. Forexample
44、, trimmers, padders, or variable inductances in tuned circuits are adjustedto give a desired response for fixed tuned equipment or to provide tracking fortuneable equipment.3.1.21 Alignment. Performing the adjustments that are necessary to returnan item to specified operation.3.1.22 Alimment kit. A
45、set of instruments or tools necessary for theadjustment of electrical or mechanical components.3.1.23 Alimment roram. A program used to align instruments and signalpaths to known characteristics.3.1.24 Ambipuitv delav. A delay model which allows the minimum and maximumpropagational delay through an
46、element to be specified. The state of the elementbetween minimum and maximum delay is unknown, and is called the ambiguity region.3.1.25 AmbijzuitvKrouv. (1) A group of replaceable items which may havefaults resulting in the same fault signature. (2) The group of items to which agiven fault is isola

A computer which represents variables by existinganalogies. Thus, a computer which solves problems by translating exi
48、sting condi-tions such as flow, temperature, pressure, angular position or voltage into relatedmechanical or electrical equivalent quantities as an analog for the existingphenomenon being investigated. In general, it is a computer which uses an analogfor each variable and produces analog as outputs.
49、 Thus, an analog computermeasures continuous quantities whereas a digital computer operates on discretedata.3.1.28 Ancillarv euiment. Equipment which is auxiliary or supplementaryto prime equipment installation. Ancillary equipment usually consists of standardoff-the-shelf items such as an oscilloscope or distortion analyzer.3.1.29 Aperture delav.
