Enhancing Public Safety Through Quality Testing and Engineering ANSI C 63. 4 • New Draft in Ballot • Comments from Review within ACIL group • Attribution: Harry Hodes, ACME Testing acil. org
Enhancing Public Safety Through Quality Testing and Engineering Improved Document • Improved organization and the logical flow • A number of much-needed technical content improvements have been incorporated into the draft document. Among many other things, these include: – the addition of Tables of LISN Impedances (with and without EUT-side Extension Cords; – expansion and clarification of what is to appear on VDUs during the Emissions Testing of ITE Equipment; and, – the addition of a new Annex L on the use of Spectrum Analyzers. acil. org
Enhancing Public Safety Through Quality Testing and Engineering Definitive Site Guidance > 1 GHz • In Clause 5. 6 of the Draft Document, a Test Site that is suitable for making radiated emissions measurements from 30 MHz to 1 GHz is considered to be suitable for making measurements above 1 GHz if EITHER: – the Site is covered with RF Absorber such that it meets the site validation criteria given in CISPR 16 -1 -4(2007) OR: – the Site is covered with RF Absorber such that at least 2. 4 m x 2. 4 m (for a 3 m measurement distance) that does not exceed 45 cm in height and has at least 20 d. B of attenuation at up to 18 GHz – Simplification of proposed methods that were considered in committee • (Question: Clause 5. 6 does not indicate if the 20 d. B attenuation is plane-wave at normal incidence or at some other angle nor the frequency range of performance). acil. org
Enhancing Public Safety Through Quality Testing and Engineering Question About Average Measurements • In Clause 4. 2. 2 of the Draft Document, the use of a 1 Hz Video Bandwidth (with data taken in Linear Mode) is mandated to provide an emulation of the Average Detector when using a Spectrum Analyzer as the Detection System. Historically, the FCC advised EMC Labs to use 10 Hz Video Bandwidth to emulate the Average Detector when using a Spectrum Analyzer as the Detection System. • (Question: Has the FCC expressed an opinion on this point? Need Clarification or coordination. ). acil. org
Enhancing Public Safety Through Quality Testing and Engineering 13 d. B Rule Redux? • Clause 11. 8. 2 of the Draft Document re-states the “ 13 d. B Rule” for AC Line Conducted Emissions, as follows: • The “ 13 d. B Rule” was deleted from 47 CFR Part 15 Subpart B Section 15. 107 several years ago. (Question: does the FCC still allow the use of the “ 13 d. B Rule”? ) acil. org
Enhancing Public Safety Through Quality Testing and Engineering Confusion About Loops and Rods • In Clause 4. 6. 2 of the Draft Document, the use of the 41” Rod Monopole is re-stated as being mandatory when making E-Field Measurements below 30 MHz. However, the Footnote that existed in Clause 4. 1. 5. 2 of ANSI C 63. 4 -2003 warning users that “some regulatory and purchasing agencies do not allow the use of a rod antenna for the measurement of radiated emissions” has been deleted from the corresponding Clause 4. 6. 2 of the Draft Document. • Question: has the FCC abandoned its opposition to the use of rod monopole antennas in making E-Field measurements below 30 MHz. If not, the Footnote should be restored to the draft document before it is published in final form. acil. org
Enhancing Public Safety Through Quality Testing and Engineering Which Reference? • Ten (out of the total of 17) Normative Reference listed in Clause 2 of the Draft Document are Undated References to Specifications/ Standards. These Undated References appear throughout the Draft Document. (If these are not converted to Dated References prior to the publication of the final version of the document, uses will face the same “constantlymoving goalposts” problem that affects those performing EMC tests to the IEC/EN Standards). acil. org
Enhancing Public Safety Through Quality Testing and Engineering New Antennas to Buy? • • In Table 1 (within Clause 4. 6. 4, the use of Log Periodic Dipole Antennas is prohibited in the 1 – 40 GHz Range when making E-Field radiated emissions measurements. Table 1 does not address the use Biconi-Log Antennas Taken together, these constitute a MAJOR change • Clause 8. 3. 4 provides explicit directions for how the distance from the EUT to the Receiving Antenna is to be measured when the Receiving Antenna is a Log Periodic Dipole Antenna. Need coordination. acil. org
Enhancing Public Safety Through Quality Testing and Engineering Cable Characterization Pain • In Clause 4. 8. 5 of the Draft Document, a new requirement is imposed that mandates that cable insertion loss characterization be repeated if the temperature variations exceed 15 degrees C. (The expectation is that a 2% (in d. B) or greater change will occur if the temperature variations exceed 15 degrees C). In other words, if the cable had a 30. 0 d. B insertion loss under original conditions, and the change were 3% when the temperature variations exceed 15 degrees C, the variation would be a worst-case factor of 0. 9 db). • – (Question: is a worst-case delta of 0. 9 d. B worth all of the extra effort needed to re-measure a set of installed range cables “in realtime”? This problem would be better addressed in the Measurement Uncertainty calculations). acil. org
Enhancing Public Safety Through Quality Testing and Engineering Pre-Scan Data is Pre-Scan Data • In Clauses 8. 4. 1. 1 and 8. 4. 1. 2 of the Draft Document, it is stated that: • “…Exploratory radiated measurements shall be performed and reported in graphical form at the measurement distance or at a closer distance than that specified for compliance to determine the emission characteristics of the EUT…. ” • In other words, if this provision is not deleted from the Draft Document before it is published in final form, it will be a requirement to include radiated emissions pre-scan data in the Test Report, notwithstanding the fact that Clause 10. 2. 8. 2 Draft Document does not address this as a requirement. acil. org
Enhancing Public Safety Through Quality Testing and Engineering The ACIL Vote • With regret, it is recommended that the ACIL vote to NEGATIVE with Comments on the ANSI C 63. 4/D 2. 5 (January 2008) Draft Document in its present form. acil. org
