EMISSION BANDWIDTH 7.1 Applicable Standard According to 15.215(c), intentional radiators operating under the alternative provisions to the general emission limits, as contained in §§15.217 through 15.257 and in Subpart E of this part, must be designed to ensure that the 20 dB bandwidth of the emission, or whatever bandwidth may otherwise be specified in the specific rule section under which the equipment operates, is contained within the frequency band designated in the rule section under which the equipment is operated. The requirement to contain the designated bandwidth of the emission within the specified frequency band includes the effects from frequency sweeping, frequency hopping and other modulation techniques that may be employed as well as the frequency stability of the transmitter over expected variations in temperature and supply voltage. If a frequency stability is not specified in the regulations, it is recommended that the fundamental emission be kept within at least the central 80% of the permitted band in order to minimize the possibility of out-of-band operation. 7.2 Test Procedure According to the ANSI 63.10-2013, the emission bandwidth test method as follows. Set span = 10kHz, centered on a transmitting channel RBW 1% 20dB Bandwidth, VBW RBW Sweep = auto Detector function = peak Trace = max hold All the trace to stabilize, use the marker-to-peak function to set the marker to the peak of the emission, use the marker-delta function to measure and record the 20dB down of the emission. 7.3 Summary of Test Results/Plots Tx Frequency 20dB Emission bandwidth(kHz) 13.56MHz 3.404 Report No.: WTX19X08059542W-6 Page 17 of 19 RF Part 15.225
