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
