(This gives bin-to-bin spacing ≤ RBW/2, so that narrowband signals are not lost between frequency bins.) e) Sweep time = auto. f) Detector = RMS (i.e., power averaging), if available. Otherwise, use sample detector mode. g) 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 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”. h) Trace average at least 100 traces in power averaging (i.e., RMS) mode. i) 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. 7.4 Environmental Conditions Temperature: 26° C Relative Humidity: 57% ATM Pressure: 1011 mbar REPORT NO.: STR15048243I-1 PAGE 37 OF 95 FCC PART 15.247 Intracom Asia Co., Ltd.

Field Strength of Spurious Emissions 8.1 Measurement Uncertainty Based on NIS 81, The Treatment of Uncertainty in EMC Measurements, the best estimate of the uncertainty of a radiation emissions measurement is +5.10 dB. 8.2 Standard Applicable According to §15.247(d), in any 100 kHz bandwidth outside the frequency band in which the spread spectrum or digitally modulated intentional radiator is operating, the radio frequency power that is produced by the intentional radiator shall be at least 20 dB below that in the 100 kHz bandwidth within the band that contains the highest level of the desired power, based on either an RF conducted or a radiated measurement, provided the transmitter demonstrates compliance with the peak conducted power limits. If the transmitter complies with the conducted power limits based on the use of RMS averaging over a time interval, as permitted under paragraph (b)(3) of this section, the attenuation required under this paragraph shall be 30 dB instead of 20 dB. Attenuation below the general limits specified in §15.209(a) is not required. In addition, radiated emissions which fall in the restricted bands, as defined in §15.205(a), must also comply with the radiated emission limits specified in §15.209(a). The emission limit in this paragraph is based on measurement instrumentation employing an average detector. The provisions in §15.35 for limiting peak emissions apply. Spurious Radiated Emissions measurements starting below or at the lowest crystal frequency. 8.3 Test Equipment List and Details Description Spectrum Analyzer EMI Test Receiver Pre-amplifier Pre-amplifier Trilog Broadband Antenna Horn Antenna Horn Antenna Loop Antenna Manufacturer R&S R&S Agilent Compliance Direction Model Serial Number Cal.

The basic equation is as follows: Corr. Ampl. = Indicated Reading + Ant. Factor + Cable Loss – Ampl. Gain The “Margin” column of the following data tables indicates the degree of compliance with the applicable limit. For example, a margin of -6dBμV means the emission is 6dBμV below the maximum limit for Class B. The equation for margin calculation is as follows: Margin = Corr.

Out of Band Emissions 9.1 Standard Applicable According to §15.247 (d) In any 100 kHz bandwidth outside the frequency band in which the spread spectrum or digitally modulated intentional radiator is operating, the radio frequency power that is produced by the intentional radiator shall be at least 20 dB below that in the 100 kHz bandwidth within the band that contains the highest level of the desired power, based on either an RF conducted or a radiated measurement, provided the transmitter demonstrates compliance with the peak conducted power limits. If the transmitter complies with the conducted power limits based on the use of RMS averaging over a time interval, as permitted under paragraph (b)(3) of this section, the attenuation required under this paragraph shall be 30 dB instead of 20 dB. Attenuation below the general limits specified in §15.209(a) is not required. In addition, radiated emissions which fall in the restricted bands, as defined in §15.205(a), must also comply with the radiated emission limits specified in §15.209(a). 9.2 Test Equipment List and Details Description Spectrum Analyzer EMI Test Receiver Pre-amplifier Pre-amplifier Trilog Broadband Antenna Horn Antenna Manufacturer R&S R&S Agilent Compliance Direction Model Serial Number Cal.

Enable the marker-delta function, then use the marker-to-peak function to move the marker to the peak of the in-band emission. Those emission must comply with the 15.209 limit for fall in the restricted bands listed in section 15.205. Note that the method of measurement KDB publication number: 913591 may be used for the radiated bandedge measurements. REPORT NO.: STR15048243I-1 PAGE 82 OF 95 FCC PART 15.247 Intracom Asia Co., Ltd. Model: 525756 According to the KDB 558074 D01 V03r02, the conducted spurious emissions test method as follows: 1. Set start frequency to DTS channel edge frequency. 2. Set stop frequency so as to encompass the spectrum to be examined. 3. Set RBW = 100 kHz. 4. Set VBW ≥ 300 kHz. 5. Detector = peak. 6. Trace Mode = max hold. 7. Sweep = auto couple. 8. Allow the trace to stabilize (this may take some time, depending on the extent of the span). 9. Use peak marker function to determine maximum amplitude of all unwanted emissions within any 100 kHz bandwidth. Ensure that the amplitude of all unwanted emissions outside of the authorized frequency band (excluding restricted frequency bands) are attenuated by at least the minimum requirements specified in section 8.1. Report the three highest emissions relative to the limit. 9.4 Environmental Conditions Temperature: 23°C Relative Humidity: 54% ATM Pressure: 1011 mbar 9.5 Summary of Test Results/Plots Please refer to the test plots as below.
