Test Procedure Use the test method descried in ANSI C63.10 clause 6.10: 1. The EUT is placed on a turntable, which is 1.5m above the ground plane and worked at highest radiated power. 2. The turntable was rotated for 360 degrees to determine the position of maximum emission level. 3. EUT is set 3m away from the receiving antenna, which is varied from 1m to 4m to find out the highest emission. 4. Set the spectrum analyzer in the following setting in order to capture the lower and upper band-edges of the emission: (a) PEAK: RBW=1MHz; VBW=3MHz; Sweep=AUTO (b) AVERAGE: RBW=1MHz; VBW=10Hz; Sweep=AUTO 6.4.

Limit (FCC Part 15C 15.247 b(3)) For systems using digital modulation in the 2400—2483.5MHz, The Peak output Power shall not exceed 1W(30dBm), As an alternative to a peak power measurement, compliance with the one Watt limit can be based on a measurement of the maximum conducted output power. Maximum Conducted Output Power is defined as the total transmit power delivered to all antennas and antenna elements averaged across all symbols in the signaling alphabet when the transmitter is operating at its maximum power control level. 8.3. Test Procedure 1, Connected the EUT’s antenna port to Spectrum Analyzer. 2, Use the test method descried in ANSI C63.10 clause 11.9.2.2.2: 1) Set span to at least 1.5 times the OBW. 2) Set RBW = 1% to 5% of the OBW, not to exceed 1 MHz. 3) Set VBW ≥ [3 × RBW]. 4) Number of points in sweep ≥ [2 × span / RBW]. (This gives bin-to-bin spacing ≤ RBW / 2, so that narrowband signals are not lost between frequency bins.). 5) Sweep time = auto. 6) Detector = RMS (i.e., power averaging), if available. Otherwise, use sample detector mode. 7) If transmit duty cycle < 98%, use a sweep trigger with the level set to enable triggering only on full power pulses. The transmitter shall operate at the maximum power control level for the entire duration of every sweep. If the EUT transmits continuously (i.e., with no OFF intervals) or at duty cycle ≥ 98%, and if each transmission is entirely at the maximum power control level, then the trigger shall be set to “free run.”. 8) Trace average at least 100 traces in power averaging (rms) mode. 9) Compute power by integrating the spectrum across the OBW of the signal using the instrument’s band power measurement function, with band limits set equal to the OBW band edges. If the instrument does not have a band power function, sum the spectrum levels (in power units) at intervals equal to the RBW extending across the entire OBW of the spectrum. Note: The cable loss and attenuator loss were offset into measure device as an amplitude offset. AUDIX Technology (Shenzhen) Co., Ltd. FCC ID:Y9E-IAD18009 Audix Technology (Shenzhen) Co., Ltd.
