Introduction This introduction is not part of IEEE Std 1241-2010, IEEE Standard for Terminology and Test Methods for Analog-to-Digital Converters

3、. This standard defines the terms, definitions, and test methods used to specify, characterize, and test analog-to-digital converters (ADCs). It is intended for the following: Individuals and organizations who specify ADCs to be purchased Individuals and organizations who purchase ADCs to be applied

4、 in their products Individuals and organizations whose responsibility is to characterize and write reports on ADCs available for use in specific applications Suppliers interested in providing high-quality and high-performance ADCs to acquirers This standard is designed to help organizations and indi

5、viduals Incorporate quality considerations during the definition, evaluation, selection, and acceptance of supplier ADCs for operational use in their equipment Determine how supplier ADCs should be evaluated, tested, and accepted for delivery to end users This standard is intended to satisfy the fol

6、lowing objectives: Promote consistency within organizations in acquiring third-party ADCs from component suppliers Provide useful practices on including quality considerations during acquisition planning Provide useful practices on evaluating and qualifying supplier capabilities to meet user require

7、ments Provide useful practices on evaluating and qualifying supplier ADCs Assist individuals and organizations judging the quality and suitability of supplier ADCs for referral to end users Several standards have previously been written that address the testing of analog-to-digital converters either

8、 directly or indirectly. These include IEEE Std 1057-2007, which describes the testing of waveform recorders. This standard has been used as a guide for many of the techniques described in this standard. IEEE Std 746-1984, which addresses the testing of analog-to-digital and digital-to-analog conver

9、ters used for PCM television video signal processing. JESD99-1, which deals with the terms and definitions used to describe analog-to-digital and digital-to-analog converters. This standard does not include test methods. IEEE Std 1241-2009 for analog-to-digital converters is intended to focus specif

10、ically on terms and definitions as well as test methods for ADCs for a wide range of applications. This standard is a revision of IEEE Std 1241-2000. This version has added additional test methods, improved guidance for selecting tests, and additional terms. Some terminology pertaining to signal-to-

11、noise ratio and related terms has been changed to be consistent with other standards. iv Copyright 2011 IEEE. All rights reserved.

47、w 1.1 Scope The material presented in this standard is intended to provide common terminology and test methods for the testing and evaluation of analog-to-digital converters (ADCs). This standard considers only those ADCs whose output values have discrete values at discrete times, i.e., they are qua

48、ntized and sampled. In general, this quantization is assumed to be nominally uniform (the input-output transfer curve is approximately a straight line) as discussed further in 1.3, and the sampling is assumed to be at a nominally uniform rate. Some but not all of the test methods in this standard ca

49、n be used for ADCs that are designed for non-uniform quantization. 1.2 Purpose This standard identifies ADC error sources and provides test methods with which to perform the required error measurements. The information in this standard is useful both to manufacturers and to users of ADCs in that it provides a basis for evaluating and comparing existing devices, as well as providing a template for writing specifications for the procurement of new ones. In some applications, the information provided by the tests described in this standard can
