Report No.: BL-SZ1680250-601 5 TEST ITEMS 5.1 Antenna Requirements 5.1.1 Standard Applicable FCC §15.203 & 15.247(b); RSS-247, 5.4 (6) An intentional radiator shall be designed to ensure that no antenna other than that furnished by the responsible party shall be used with the device. The use of a permanently attached antenna or of an antenna that uses a unique coupling to the intentional radiator shall be considered sufficient to comply with the provisions of this section.
Report No.: BL-SZ1680250-601 5.2 Output Power 5.2.1 Test Limit FCC § 15.247(b); RSS-247, 5.4 (4) For systems using digital modulation in the 902-928 MHz, 2400-2483.5 MHz, and 5725-5850 MHz bands: 1 Watt. 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.
Report No.: BL-SZ1680250-601 Set RBW ≥ OBW if possible; otherwise, set RBW to the largest available value. Set VBW ≥ RBW. Set detector = peak or average. The zero-span measurement method shall not be used unless both RBW and VBW are > 50/T and the number of sweep points across duration T exceeds 100.
Report No.: BL-SZ1680250-601 5.3 6dB Bandwidth 5.3.1 Limit FCC §15.247(a); RSS-GEN, 6.6 Make the measurement with the spectrum analyzer's resolution bandwidth (RBW) = 100 kHz. In order to make an accurate measurement, set the span greater than RBW. The 6 dB bandwidth must be greater than 500 kHz. 5.3.2 Test Setup See section 4.4.1 for test setup description for the antenna port.
Report No.: BL-SZ1680250-601 5.4 Conducted Spurious Emission 5.4.1 Limit FCC §15.247(d); RSS-247, 5.5 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.
Report No.: BL-SZ1680250-601 Emission level measurement Use the following spectrum analyzer settings: Span = wide enough to capture the peak level of the in-band emission and all spurious emissions (e.g., harmonics) from the lowest frequency generated in the EUT up through the 10th harmonic. Typically, several plots are required to cover this entire span.
Report No.: BL-SZ1680250-601 5.5 Band Edge (Authorized-band band-edge) 5.5.1 Limit FCC §15.247(d); RSS-GEN, 8.9, RSS-247, 5.5 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.
Report No.: BL-SZ1680250-601 Reference level: As required to keep the signal from exceeding the maximum instrument input mixer level for linear operation. In general, the peak of the spectral envelope shall be more than [10 log (OBW/RBW)] below the reference level. Specific guidance is given in 4.1.5.2. Attenuation: Auto (at least 10 dB preferred).
Report No.: BL-SZ1680250-601 5.6 Conducted Emission 5.6.1 Limit FCC §15.207; RSS-GEN, 8.8 For an intentional radiator that is designed to be connected to the public utility (AC) power line, the radio frequency voltage that is conducted back onto the AC power line on any frequency within the band 150 kHz to 30 MHz shall not exceed the limits in the following table, as measured using a 50µH/50Ω...

In addition, radiated emissions which fall in the restricted bands, as defined in FCC section 15.205(a), must also comply with the radiated emission limits specified in FCC section 15.209(a).
Report No.: BL-SZ1680250-601 5.8 Band Edge (Restricted-band band-edge) 5.8.1 Limit FCC §15.209&15.247(c); RSS-247, 5.5 Radiated emission outside the frequency band attenuation below the general limits specified in FCC section 15.209(a) is not required. In addition, radiated emissions which fall in the restricted bands, as defined in FCC section 15.205(a), must also comply with the radiated emission limits specified in FCC section 15.209(a).
Report No.: BL-SZ1680250-601 5.9 Power Spectral density (PSD) 5.9.1 Limit FCC §15.247(d); RSS-247, 5.2 (2) The same method of determining the conducted output power shall be used to determine the power spectral density. If a peak output power is measured, then a peak power spectral density measurement is required. If an average output power is measured, then an average power spectral density measurement should be used.

Report No.: BL-SZ1680250-601 A.3 Conducted Spurious Emissions Test Data Note: For Multiple transmitter output, the quantity 10 log (NANT) dB is added to each spectrum value before comparing to the emission limit. When testing out-of-band and spurious emissions against relative emission limits, tests may be performed on each output individually without summing or adding 10 log(NANT) if the measurements are made relative to the in-band emissions on the individual outputs.
