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
The maximum measurement uncertainty is evaluated as: 9kHz~150kHz: 3.58dB 150kHz~30MHz: 3.20dB Radiated Emission Measurement The maximum measurement uncertainty is evaluated as: Coaxial: 9kHz~30MHz: 2.59dB Coplanar: 9kHz~30MHz: 2.60dB Horizontal: 30MHz~200MHz: 3.85dB
200MHz~1GHz: 4.36dB 1GHz~40GHz: 4.98dB Vertical: 30MHz~200MHz: 4.06dB 200MHz~1GHz: 5.28dB 1GHz~40GHz: 4.91dB Spurious Emissions, Conducted Measuring Uncertainty for a Level of Confidence of 95% (U=2Uc(y)): 2.3dB Output Power Measuring Uncertainty for a Level of Confidence of 95% (U=2Uc(y)): 1.5dB Power Spectrum Density Measuring Uncertainty for a Level of Confidence of 95% (U=2Uc(y)): 2.3dB Occupied Bandwidth Measuring Uncertainty for a Level of Confidence of 95% (U=2Uc(y)): 3.2%

Notes:
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 test, every axis (X, Y, Z) was also verified. The test results shown in the following
sections represent the worst-case emissions.
3. EUT supports one configuration only in 802.11ax full RU mode. 4. For test Items "26dB & 99% Bandwidth" and "6dB Bandwidth", we only evaluated the Ant 1 RF port.

Trace mode = max hold. 99% Bandwidth 1. Set center frequency to the nominal EUT channel center frequency. 2. Set span = 1.5 times to 5.0 times the OBW. 3. Set RBW = 1% to 5% of the OBW 4. Set VBW 3×RBW 5. Detector = Peak. 6. Use the 99% power bandwidth function of the instrument. 6.2.4. Test Setup

6.5.3. Test Setting 1. Analyzer was set to the center frequency of the UNII channel under investigation 2. Span was set to encompass the entire 26dB EBW of the signal. 3. RBW = 1MHz (510kHz, if measurement bandwidth of Maximum PSD is specified in 500 kHz) 4. VBW = 3 × RBW 5. Number of sweep points 2 × (span / RBW) 6. Detector = power averaging (Average) 7. Sweep time = auto 8. Trigger = free run 9. Trace average at least 100 traces in power averaging (rms) mode; however, the number of traces to be
averaged shall be increased above 100 as needed to ensure that the average accurately represents the true average over the on and off periods of the transmitter. 10. Use the peak search function on the instrument to find the peak of the spectrum and record its value. 11. Add 10*log(1/x), where x is the duty cycle, to the measured power in order to compute the average power during the actual transmission times (because the measurement represents an average over both the on and off times of the transmission). For example, add 10*log(1/0.25) = 6 dB if the duty cycle is 25 percent. 6.5.4. Test Setup

6.6. Frequency Stability Measurement 6.6.1. Test Limit Manufactures of U-NII devices are responsible for ensuring frequency stability such that an emission is maintained within the band of operation under all conditions of normal operation as specified in the user's manual. 6.6.2. Test Procedure Frequency Stability Under Temperature Variations: The equipment under test was connected to an external AC or DC power supply and input rated voltage. RF output was connected to a frequency counter or spectrum analyzer via feed through attenuators. The EUT was placed inside the temperature chamber. Set the spectrum analyzer RBW low enough to obtain the desired frequency resolution and measure EUT 20°C operating frequency as reference frequency. Turn EUT off and set the chamber temperature to highest. After the temperature stabilized for approximately 30 minutes recorded the frequency. Repeat step measure with 10°C decreased per stage until the lowest temperature reached. Frequency Stability Under Voltage Variations: Set chamber temperature to 20°C. Use a variable AC power supply / DC power source to power the EUT and set the voltage to rated voltage. Set the spectrum analyzer RBW low enough to obtain the desired frequency resolution and recorded the frequency. Reduce the input voltage to specify extreme voltage variation (±15%) and endpoint, record the maximum frequency change. 6.6.3. Test Setup
