Conducted Band Edge and Out-of-Band Emissions 7.5.1.Test Limit The limit for out-of-band spurious emissions at the band edge is 30dB below the fundamental emission level, as determined from the in-band power measurement of the DTS channel performed in a 100 kHz bandwidth per the PSD procedure. 7.5.2.Test Procedure Used ANSI C63.10 Section 11.11 7.5.3.Test Setting Reference level measurement 1. Set instrument center frequency to DTS channel center frequency 2. Set the span to ≥ 1.5 times the DTS bandwidth 3. Set the RBW = 100 kHz 4. Set the VBW ≥ 3 x RBW 5. Detector = peak 6. Sweep time = auto couple 7. Trace mode = max hold 8. Allow trace to fully stabilize Emission level measurement 1. Set the center frequency and span to encompass frequency range to be measured 2. RBW = 1.3MHz 3. VBW = 4MHz 4. Detector = Peak 5. Trace mode = max hold 6. Sweep time = auto couple 7. The trace was allowed to stabilize Report No.: 1911RSU033-U1 FCC ID: 2ABLK-GS4227E Page Number: 51 of 166 Test Notes 1. RBW was set to 1.3MHz rather than 100 kHz in order to increase the measurement speed. 2. The display line shown in the following plots denotes the limit at 30dB below the fundamental emission level measured in a 100 kHz bandwidth. However, since the traces in the following plots are measured with a 1.3MHz RBW, the display line may not necessarily appear to be 30dB below the level of the fundamental in a 1.3MHz bandwidth. 3. For plots showing conducted spurious emissions near the limit, the frequencies were investigated with a reduced RBW to ensure that no emissions were present. 7.5.4.Test Setup Report No.: 1911RSU033-U1 FCC ID: 2ABLK-GS4227E Page Number: 52 of 166 7.5.5.Test Result Product GigaSpire Temperature 25°C Test Engineer Bacon Dong Relative Humidity 54% Test Site TR3 Test Date 2019/12/04 Test Mode Data Rate / MCS Channel No. Frequency (MHz) Limit (dBc) Result Ant 0 / Ant 0 + 1 802.11b 1Mbps 01 2412 30 Pass 802.11b 1Mbps 06 2437 30 Pass 802.11b 1Mbps 11 2462 30 Pass 802.11g 6Mbps 01 2412 30 Pass 802.11g 6Mbps 06 2437 30 Pass 802.11g 6Mbps 11 2462 30 Pass 802.11n-HT20 MCS0 01 2412 30 Pass 802.11n-HT20 MCS0 06 2437 30 Pass 802.11n-HT20 MCS0 11 2462 30 Pass 802.11n-HT40 MCS0 03 2422 30 Pass 802.11n-HT40 MCS0 06 2437 30 Pass 802.11n-HT40 MCS0 09 2452 30 Pass 802.11ax-HE20 MCS0 01 2412 30 Pass 802.11ax-HE20 MCS0 06 2437 30 Pass 802.11ax-HE20 MCS0 11 2462 30 Pass 802.11ax-HE40 MCS0 03 2422 30 Pass 802.11ax-HE40 MCS0 06 2437 30 Pass 802.11ax-HE40 MCS0 09 2452 30 Pass Report No.: 1911RSU033-U1 FCC ID: 2ABLK-GS4227E Page Number: 53 of 166 802.11b Out-of-Band Emissions - Ant 0 / Ant 0 + 1 100kHz PSD reference Level Channel 01 (2412MHz) Low Band Edge Spurious Emission Channel 06 (2437MHz) Spurious Emission Report No.: 1911RSU033-U1 FCC ID: 2ABLK-GS4227E Page Number: 54 of 166 802.11b Out-of-Band Emissions - Ant 0 / Ant 0 + 1 Channel 11 (2462MHz) High Band Edge Spurious Emission Report No.: 1911RSU033-U1 FCC ID: 2ABLK-GS4227E Page Number: 55 of 166 802.11g Out-of-Band Emissions - Ant 0 / Ant 0 +1 100kHz PSD reference Level Channel 01 (2412MHz) Low Band Edge Spurious Emission Channel 06 (2437MHz) Spurious Emission Report No.: 1911RSU033-U1 FCC ID: 2ABLK-GS4227E Page Number: 56 of 166 802.11g Out-of-Band Emissions - Ant 0 / Ant 0 +1 Channel 11 (2462MHz) High Band Edge Spurious Emission Report No.: 1911RSU033-U1 FCC ID: 2ABLK-GS4227E Page Number: 57 of 166 802.11n-HT20 Out-of-Band Emissions - Ant 0 / Ant 0 + 1 100kHz PSD reference Level Channel 01 (2412MHz) Low Band Edge Spurious Emission Channel 06 (2437MHz) Spurious Emission Report No.: 1911RSU033-U1 FCC ID: 2ABLK-GS4227E Page Number: 58 of 166 802.11n-HT20 Out-of-Band Emissions - Ant 0 / Ant 0 + 1 Channel 11 (2462MHz) High Band Edge Spurious Emission Report No.: 1911RSU033-U1 FCC ID: 2ABLK-GS4227E Page Number: 59 of 166 802.11n-HT40 Out-of-Band Emissions - Ant 0 / Ant 0 + 1 100kHz PSD reference Level Channel 03 (2422MHz) Low Band Edge Spurious Emission Channel 06 (2437MHz) Spurious Emission Report No.: 1911RSU033-U1 FCC ID: 2ABLK-GS4227E Page Number: 60 of 166 802.11n-HT40 Out-of-Band Emissions - Ant 0 / Ant 0 + 1 Channel 09 (2452MHz) High Band Edge Spurious Emission Report No.: 1911RSU033-U1 FCC ID: 2ABLK-GS4227E Page Number: 61 of 166 802.11ax-HE20 Out-of-Band Emissions - Ant 0 / Ant 0 + 1 100kHz PSD reference Level Channel 01 (2412MHz) Low Band Edge Spurious Emission Channel 06 (2437MHz) Spurious Emission Report No.: 1911RSU033-U1 FCC ID: 2ABLK-GS4227E Page Number: 62 of 166 802.11ax-HE20 Out-of-Band Emissions - Ant 0 / Ant 0 + 1 Channel 11 (2462MHz) High Band Edge Spurious Emission Report No.: 1911RSU033-U1 FCC ID: 2ABLK-GS4227E Page Number: 63 of 166 802.11ax-HE40 Out-of-Band Emissions - Ant 0 / Ant 0 + 1 100kHz PSD reference Level Channel 03 (2422MHz) Low Band Edge Spurious Emission Channel 06 (2437MHz) Spurious Emission Report No.: 1911RSU033-U1 FCC ID: 2ABLK-GS4227E Page Number: 64 of 166 802.11ax-HE40 Out-of-Band Emissions - Ant 0 / Ant 0 + 1 Channel 09 (2452MHz) High Band Edge Spurious Emission Report No.: 1911RSU033-U1 FCC ID: 2ABLK-GS4227E Page Number: 65 of 166 7.6.
