Technical Characteristic Test 4.1 Band Edge Requirement Emissions radiated outside of the specified frequency bands, except for harmonics, shall be attenuated by at least 50 dB below the level of the fundamental or to the general radiated emission limits in § 15.209, whichever is the lesser attenuation. Test Procedures(ANSI C63.10-2013 6.10) a) Connect the spectrum analyzer to the EUT using an appropriate RF cable connected to the EUT output. Configure the spectrum analyzer settings as described in step e) (be sure to enter all losses between the unlicensed wireless device output and the spectrum analyzer). b) Set the EUT to the lowest frequency channel (for the hopping on test, the hopping sequence shall include the lowest frequency channel). c) Set the EUT to operate at maximum output power and 100% duty cycle, or equivalent “normal mode of operation”. d) Perform the test as follows: 1) Span : Wide enough to capture the peak level of the emission operating on the channel closest to the band edge, as well as any modulation products that fall outside of the authorized band of operation. 2) RBW : 100 kHz 3) VBW : 300 kHz 4) Detector : Peak 5) Sweep time = Coupled 6) Trace : Max hold 7) Attenuation : Auto(at least 10 dB preferred) 8) Allow trace to fully stabilize e) Set the marker on the emission at the band edge, or on the highest modulation product outside of the band, if this level is greater than that at the band edge. Enable the marker- delta function, and then use the marker-to-peak function to move the marker to the peak of the in-band emission. f) Set the EUT to the highest frequency channel (for the hopping on test, the hopping sequence shall include the highest frequency channel) and repeat step c) through step d). g) The band-edge measurement shall be reported by providing plot(s) of the measuring instrument display; the plot axes and the scale units per division shall be clearly labeled. Tabular data may be reported in addition to the plot(s). Test results: Complies See next pages for actual measured spectrum plots. CTK-D151-06 R107 Rev.0

The center of the Loop Test Antenna is 1m above the ground. During the measurement the Loop Test Antenna rotates about its vertical axis for maximum response at each azimuth about the EUT. 2) In the frequency rage above 30 MHz, Bi-Log Test Antenna(30 MHz to 1 GHz) and Horn Antenna(above 1 GHz) are used. Test Antenna is 3m away from the EUT. Test Antenna height is carried from 1m to 4m above the ground to determine the maximum value of the field strength. The emissions levels at both horizontal and vertical polarizations should be tested. Test Settings: Frequency Range = 9 kHz ~ 12.75 GHz (10th harmonic) a) RBW = 1 MHz for f ≥ 1 GHz, 120 kHz for f < 1 GHz, 9 kHz for f < 30 MHz b) VBW ≥ RBW c) Sweep time = auto couple CTK-D151-06 R107 Rev.0
