Note: The EUT supports Cyclic Delay Diversity (CDD) mode, and CDD signals are correlated.
For CDD transmissions, directional gain is calculated as follows, NANT = 2, NSS = 1.
If all antennas have the same gain, GANT, Directional gain = GANT + Array Gain, where Array Gain is as follows. · For power spectral density (PSD) measurements on all devices,
Array Gain = 10 log (NANT/ NSS) dB = 3.01; · For power measurements on IEEE 802.11 devices,
Array Gain = 0 dB for NANT 4;

5. Decision Rules and Measurement Uncertainty
5.1. Decision Rules
The Decision Rule is based on Simple Acceptance in accordance with ISO Guide 98-4: 2012 Clause 8.2. (Measurement uncertainty is not taken into account when stating conformity with a specified requirement.)
5.2. Measurement Uncertainty
Where relevant, the following test uncertainty levels have been estimated for tests performed on the EUT as specified in CISPR 16-4-2. This uncertainty represents an expanded uncertainty expressed at approximately the 95% confidence level using a coverage factor of k = 2. AC Conducted Emission Measurement
Measurement Uncertainty for a Level of Confidence of 95% (U=2Uc(y)): 9kHz~150kHz: 3.74dB 150kHz~30MHz: 3.44dB Radiated Disturbance Measurement Uncertainty for a Level of Confidence of 95% (U=2Uc(y)): Horizontal: 30MHz~300MHz: 5.04dB 300MHz~1GHz: 4.95dB 1GHz~40GHz: 6.40dB Vertical: 30MHz~300MHz: 5.24dB 300MHz~1GHz: 6.03dB 1GHz~40GHz: 6.40dB Spurious Emissions, Conducted Measuring Uncertainty for a Level of Confidence of 95% (U=2Uc(y)): 0.78dB Output Power Measuring Uncertainty for a Level of Confidence of 95% (U=2Uc(y)): 1.13dB Power Spectrum Density Measuring Uncertainty for a Level of Confidence of 95% (U=2Uc(y)): 1.15dB Occupied Bandwidth Measuring Uncertainty for a Level of Confidence of 95% (U=2Uc(y)): 0.28%

Remark:
1. The analyzer plots shown in this section were all taken with a correction table loaded into the analyzer.
The correction table was used to account for the losses of the cables and attenuators used as part of the
system to connect the EUT to the analyzer at all frequencies of interest.
2. For radiated emission tests, every axis (X, Y, Z) was also verified. The test results shown in the following
sections represent the worst-case emissions.
3. The EUT supports one configuration only in 802.11ax full RU mode.
4. For test Item "6dB Bandwidth", we only evaluated the Ant 1 RF port.

Report No.: 2206RSU048-U1 6.2. 6dB Bandwidth Measurement 6.2.1. Test Limit The minimum 6dB bandwidth shall be at least 500 kHz. 6.2.2. Test Procedure ANSI C63.10 - 2013 - Section 11.8 6.2.3. Test Setting 1. The Spectrum's automatic bandwidth measurement capability was used to perform the 6dB bandwidth
measurement. The "X" dB bandwidth parameter was set to X = 6. The bandwidth measurement was not influenced by any intermediate power nulls in the fundamental emission. 2. Set RBW = 100 kHz 3. VBW 3 × RBW 4. Detector = Peak 5. Trace mode = Max hold 6. Sweep = Auto couple 7. Allow the trace to stabilize 6.2.4. Test Setup
6.2.5. Test Result Refer to Appendix A.2.

Report No.: 2206RSU048-U1
6.3. Output Power Measurement 6.3.1. Test Limit The maximum output power shall be less 1 Watt (30dBm). The conducted output power limit specified in paragraph FCC Part 15.247(b) of this section is based on the use of antennas with directional gains that do not exceed 6 dBi. If transmitting antennas of directional gain greater than 6 dBi are used, the conducted output power from the intentional radiator shall be reduced below the stated values in paragraphs FCC Part 15.247(b)(3) of this section, as appropriate, by the amount in dB that the directional gain of the antenna exceeds 6 dBi. 6.3.2. Test Procedure ANSI C63.10 - 2013 - Section 11.9.2.3.2 6.3.3. Test Setting Average Power Measurement Average power measurements were performed only when the EUT was transmitting at its maximum power control level using a broadband power meter with a pulse sensor. The power meter implemented triggering and gating capabilities which were set up such that power measurements were recorded only during the ON time of the transmitter. 6.3.4. Test Setup
6.3.5. Test Result Refer to Appendix A.3.

6.4. Power Spectral Density Measurement 6.4.1. Test Limit The maximum permissible power spectral density is 8dBm in any 3 kHz band. The same method of determining the conducted output power shall be used to determine the power spectral density. 6.4.2. Test Procedure ANSI C63.10 - 2013 - Section 11.10.5 6.4.3. Test Setting 1. Measure the duty cycle (x) of the transmitter output signal. 2. Set instrument center frequency to DTS channel center frequency. 3. Set span to at least 1.5 times the OBW. 4. RBW = 10 kHz. 5. VBW = 30 kHz. 6. Detector = RMS. 7. Ensure that the number of measurement points in the sweep 2 x span/RBW. 8. Sweep time = auto couple. 9. Don't use sweep triggering. Allow sweep to "free run". 10. Employ trace averaging (RMS) mode over a minimum of 100 traces. 11. Use the peak marker function to determine the maximum amplitude level. 12. Add 10 log (1/x), where x is the duty cycle measured in step (a, to the measured PSD to compute the
average PSD during the actual transmission time. If measured value exceeds requirement specified by regulatory agency, then reduce RBW (but no less than 3 kHz) and repeat (note that this may require zooming in on the emission of interest and reducing the span to meet the minimum measurement point requirement as the RBW is reduced).

Average Field Strength Measurements 1. Analyzer center frequency was set to the frequency of the radiated spurious emission of interest 2. RBW = 1MHz 3. VBW 1/T 4. As an alternative, the instrument may be set to linear detector mode. Ensure that video filtering is applied
in linear voltage domain (rather than in a log or dB domain). Some instruments require linear display mode in order to accomplish this. Others have a setting for Average-VBW Type, which can be set to "Voltage" regardless of the display mode 5. Detector = Peak 6. Sweep time = auto 7. Trace mode = max hold 8. Allow max hold to run for at least 50 times (1/duty cycle) traces 6.7.4. Test Setup
