Accredited Standards Committee C63® - EMC Subcommittee 1: Techniques and Developments Zhong Chen SC1 Chair 11-14-2013 1 Accredited Standards Committee C63® - EMC Scope SC1 Techniques and Developments Scope Subcommittee 1 provides the technical expertise and resources necessary for maintaining existing and newly proposed C63® approved standards documents. New or existing measurement techniques and associated instrumentation, measurement methods, and limits development related to EMC are incorporated as assigned by the Main Committee ASC C63®. 2 Accredited Standards Committee C63® - EMC Memberships • Subcommittee 1 and Working Group Membership List • Two new members: Mits Samoto and Khairul Aidi Zainal 3 Chair Chen, Zhong Vice Chair Hodes, Harry Secretary O’Neil, Janet (non-voting) Name Role within Subcommittee 1 Affiliation Arthurs, Mark Attayi, Masud Camell, Dennis Chen, Zhong DeLisi, Bob Ghizzone, Dean Griffin, Andy Hare, Ed (non-voting) Harrington, Tim Heirman, Don Hodes, Harry Hofmann, Bob Hoolihan, Dan Kiemel, Greg Klinger, Jeff Kuczynski, Victor Lombardi, Rick Long, Randy O’Neil, Janet Parker, Doug Pettit, Ghery Potts.

Ballot met the approval requirements % approval (majority test) entire ballot body: 73% % approval (2/3rd test) returned votes, excluding abstentions: 82.6 % 4 negative ballots 5 Third Recirculation Subjects • • • • • • 2 dB rule for cables and plug-ins (NR-new PINS) Rack mounted equipment set up (NR-E) Remove regulatory application of C63.4 (NR) Revise procedures above 1 GHz (NR-new PINS) Typo—change C63.26 to C63.23 (NR-E) Modify that table top material does not always affects measurements (NR-E) • When hybrid antennas are used above 1 GHz the test site is not to be qualified using absorber patch (NR) November 2013 C63® Meeting Slide 6 Third Recirculation Subjects • Recal for hybrids made same as other antennas (NR-E) • 1 dB hybrid antenna tolerance is justified (NR) • Date C63® references (NR) NOTE: PINS proposal to cover many of these items will be discussed later in the WG meeting November 2013 C63® Meeting Slide 7 Third Recirculation Subjects • Enter items considered for future work into present document (NR-new PINS) • Do not lose outstanding issue for next edition (NRnew PINS) • • • • • Clarifying the use of CISPR 16-4-2 (MU)(NR-E) Remove Annex N-waiting for C63.5 (NR-T) Use “device” consistently (NR-E) Remove antenna cal by accredited cal labs (NR-T) Requirements for bonding impedance (NR-T) November 2013 C63® Meeting Slide 8 Motion • Motion to request that C63.4 final comment resolutions be circulated to the balloting group, and subsequently C63.4 to move to publication. 9 WG C63.5 Status • Several revisions were processed, last version D4.8 • IEEE reviewed and provided editorial comments – Aug 2013 • Sent to main committee – Sept 2013 • Balloting started – Oct 2013 • Ballot ended – Nov 8, 2013 SC1 – May 2013 10 WG C63.5 Status IEEE statement of results There were 26 people in the ballot pool and 20 balloters responded. Of the 20 responses, there were 6 disapprovals (with comments), 1 abstention, 10 approvals (with comments) and 3 approvals (with no comments). The ballot did not pass according to the C63 Operating Procedures as the majority of the balloting group did not approve the document (13 out of 26 = 50%). SC1 – May 2013 11 WG C63.5 Plans • Compile comments and develop response. • Incorporate comments into another draft for new ballot • Re-circ ballot February next year SC1 – May 2013 12 WG C63.25 status • Measure TD and sVSWR at 4 spots and 2 heights in several labs. Need test plan Measure to 12 GHz Determine correlation between two methods. NWEMC chamber(s) measurement UL chamber measurement • Look at using PODS/bicon as TD antenna Measure TD ringdown signature Study modeling of antennas o Compare different antennas o Revise current draft to update IEEE formatting. SC1 - May 2013 13 WG C63.25 Plans Measure UL SAC in November 2013 Measure other site(s) ? Send out revised draft to WG by February 2014 SC1 - May 2013 14 C63.26/10 • WWG met on November 11th and 12th, 2013 1. 28 attendees (5 via webinar) + 9 observers 2. C63.10-2013 published on September 13, 2013 3. Reviewed draft of C63.26-201x 4. New draft to be compiled end of January, 2014 and balloted within Subcommittee 1. 5. Voting results and comments to considered at next WWG meeting 6. Revised PINS submitted for approval - compliance testing of (licensed) transmitters used in licensed radio services C63.7 • New PINS C63.7 • Guide for Construction of Open-Area Test Sites for Performing Radiated Emission Measurements (Free Space OATS) • Working groups formed with Don Heirman, Bob Hofmann, Harry Hodes, Cooer LaFond and Ray Klouda • Initial draft is circulated with in the working group. 16
