2、minology and Test Methods for Circuit Probes Sponsor Waveform Generation, Measurement, and Analysis Technical Committee of the IEEE Instrumentation and Measurement Society Approved 11 December 2013 IEEE-SA Standards Board Abstract: Currently, no defined, industry-accepted method exists for character
3、izing the performance of electrical circuit probes. Each vendor has its own proprietary methods for characterization, leaving probe customers and users without a valid means of comparing probe performance and/or of understanding the circuit-loading effect of the probe. Methods for measuring paramete
4、rs indicative of a probes or probe systems performance and guidance on the design and use of a test fixture for measuring probe performance are provided by this standard. An industry-accepted, unbiased means for characterizing probe performance is given by these methods. High-impedance voltage probe
5、s that are used to measure the performance of electrical circuits are considered by this standard. The probe systems may include waveform acquisition hardware and software and signal/waveform analysis software. The probe will include the mechanism by which the circuit is contacted. This method and s
6、tandard will be applicable to all individual probes having one signal conductor and one ground conductor or two signal conductors, and having an input impedance at least five times greater than the impedance of the circuit under test.

Translations The IEEE consensus development
15、process involves the review of documents in English only. In the event that an IEEE standard is translated, only the English version published by IEEE should be considered the approved IEEE standard. Official statements A statement, written or oral, that is not processed in accordance with the IEEE-
16、SA Standards Board Operations Manual shall not be considered or inferred to be the official position of IEEE or any of its committees and shall not be considered to be, or be relied upon as, a formal position of IEEE. At lectures, symposia, seminars, or educational courses, an individual presenting
17、information on IEEE standards shall make it clear that his or her views should be considered the personal views of that individual rather than the formal position of IEEE. Comments on standards Comments for revision of IEEE Standards documents are welcome from any interested party, regardless of mem
18、bership affiliation with IEEE. However, IEEE does not provide consulting information or advice pertaining to IEEE Standards documents. Suggestions for changes in documents should be in the form of a proposed change of text, together with appropriate supporting comments. Since IEEE standards represen
19、t a consensus of concerned interests, it is important that any responses to comments and questions also receive the concurrence of a balance of interests. For this reason, IEEE and the members of its societies and Standards Coordinating Committees are not able to provide an instant response to comme
20、nts or questions except in those cases where the matter has previously been addressed. For the same reason, IEEE does not respond to interpretation requests.

Participants At the time this IEEE standard was completed, the Subcommittee on Probe Standards (IM/WM that is, they should not generate electromagnetic interference that affects the performance of other instruments or components in the system. External disturbance or interference can come
38、from computers, radio frequency (RF) devices, communication signals, and so on. The user of the standard should verify that the test system is not affected by external disturbances. The user should also be aware of possible damage to sensitive electronics by electrostatic discharge. Consequently, th
39、e test instrumentation and device under test should be placed on antistatic surfaces that are connected to earth ground and have a surface resistance greater than 106. The operator of the instruments should be connected to earth ground using wrist straps or similar devices. 1.3.3 Test equipment The
40、performance of the test equipment used for these tests should significantly exceed the desired performance of the circuit probe under test. How significantly more the performance of the test equipment must exceed that of the probe under test is dependent on user requirements for accuracy and uncerta
41、inty. Testing labs should be compliant with ISO/IEC 17025 to ensure quality of measurement results. In particular, traceability of instrumental calibration to a known standard is important. The test equipment required to perform the tests given in this standard are described in Clause 4. 1.3.4 Test
42、selection The test methods given in this standard are suggested methods for measuring the parameters that are indicative of probe performance. These test methods, although general, provide a logical process in which to acquire parameter information. To provide subsequent comparability with other mea
43、surements of the same parameter, deviation from the methods described in this standard should be noted by the user.
