C63.4
Third Recirculation ballot sent to balloting group August 2013; closed in September 2013. 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
November 2013 C63® Meeting Slide 6
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 7
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 8
Third Recirculation Subjects
• Enter items considered for future work into present document (NR-new PINS)
• Do not lose outstanding issue for next edition (NR-new 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)
