4. Update on Working Groups
C63.2 Specifications for Electromagnetic Noise and Field Strength Measurement Instrumentation
Working Group Chair: Werner Schaefer
• Published this month

5. C63.4 Full Revision
Chair: Don Heirman

6. Progress Major activity since last face to face meeting:
Reviewed many inputs on the use of “shall” and “should” for normative and informative perspective, respectively in clauses 1 through 5.
Most discussed was need to perform NSA to cover EUT heights of up to 3 meters.
Developed three “teams” to amend, where appropriate, parts of 2014 standard.
Held monthly webinars after November 2016 meeting to review particular areas needing discussion and team output

7. Changes proposed to date
Added phase for LISNs
Proper use of shall/should aggressively pursued
Added new Clause 1.4 (dimensional tolerances)
Measurement uncertainty now applies to entire document
Revised definitions (bin size, arrangements, configurations, auxiliary, peripheral, test setup, etc.
New sub-clause for preamps
Clarified average detection
Reformatted tables 1, 2 and 3 on antenna use
Active loop, monopole and horn overload addressed

8. Changes proposed to date
Calibration of measuring equipment was updated to cover all ancillary equip.
Use 2017 version of C63.5 and new version of C63.2
Continue to use undated ANSI references
Clarified turntable below and above 1 GHz (metallic, non-metallic)
Moved text around to where it belongs without changing requirements
Vertical coupling plane was clarified for table, floor, combination equipment
Test site below 30 MHz to use ground plane without NSA needed
Annex D not addressed as it is handled the in C63.4a Amendment
Removed patch of absorber on ground plan; all >1 GHz must meet SVSWR to 18 GHz (applicable to 40 GHz)
In-situ testing is aligned with C63.10 content

9. Monday Meeting Next steps:
Presented draft to date and discussed further changes as needed.
Includes consideration of all interpretations
Reviewed topics to be postponed until after the present one in preparation is published
Prepare draft to ballot probably by EOY
PINS by September for SC1 review
Publication in late 2018 or early 2019

10. Accredited Standards Committee C63® - EMC
C63.4a Limited Amendment
Chaired by: Don Heirman

11. Tuesday Meeting Met on 5/9/17 Ballot closed on 6 April.
Two negative ballots and 2 approvals with comments.
Reviewed all comments and developed resolutions to amend the draft

12. Tuesday Meeting Next steps:
Circulate ballot comment resolutions to SC1 for approval.
Approval will allow a recirculation ballot to occur with changes based on the comment resolutions
Send amended draft to secretariat along with the comment resolution for a recirculation ballot in May.
If ballot successful, publication by August

13. Motion to Correct Far field equation
A motion was approved in the steering committee to correct the far field equation in C The correction is intended to be included in C63.4a.

14. C63.25
Chaired by: Dan Sigouin

15. Background on New C63.25 WG
In February 2016 it was decided and approved by the SC1 Chair that the C63.4 WG (Don Heirman) will continue addressing the site validation requirements below 1 GHz.
C63.25 is only addressing the frequency range 1GHz to 18 GHz regarding site validation.
New standard – Plan to circulate a draft to SC1 in first quarter of 2017
The TD SVSWR Method in the current draft of C63.25 is for all intent and purposes complete.

16. PINS is current (see website)
Scope:
This standard provides methods of measurement requirements for the validation of radiated emission test sites in the frequency range of 1 GHz to 18 GHz. These requirements are applicable to fully anechoic rooms (FAR) and when spectrally treated on the floor open-area test sites (OATS), fully- and partially-covered OATS, semi-anechoic chambers (SAC).

17. The TD SVSWR measurement methods for all intends and purposes are complete
Working group is working on an informative annex to include instrumentation measurement uncertainties
WG identified contributors for the measurement uncertainties
WG intends to circulate in SC1 by end of 2017.

18. C63.5 WG STATUS UPDATE
Chaired by Bob DeLisi

19. C63.5 Update May 2016 C63.5-2017 was officially published in May 2017
A new working group is called to start C63.5 next edition.
Motion: to approve new PINS for C63.5

20. New Businesses
C63.23 is currently 5 years old. There were discussions to form a new working group to update to include new measurement needs.

21. Interpretation requests
4 recent interpretation requests were received since last meeting
2 have been approved by main committee and posted
