The following tables show measurements of any emissions that fell into the restricted bands of §15.205. The tables show the worst-case emissions measured from the EUT. For frequencies above 18.0 GHz, a measurement distance of 1 meter was used. The noise floor was a minimum of 6 dB below the limits. The emissions in the restricted bans must meet the limits specified in §15.209. Tabular data for each of the spurious emissions is shown below for each of the units. Plots of the band edges are also shown. Result All emissions in the restricted bands of §15.205 met the limits specified in §15.209; therefore, the EUT complies with the specification.

427 West 12800 South, Draper, UT 84020 Graph 10: Radiated Upper Band Edge Plot 5.6 §15.247(e) Maximum Average Power Spectral Density The maximum average power spectral density conducted from the intentional radiator of the antenna shall not be greater than 8 dBm in any 3 kHz band during any time interval of continuous transmission. Results of this testing are summarized. The antenna gain is 2 dBi E[dBµV/m] = EIRP[dBm] - 20 log (d[m]) + 104.77 E[dBµV/m] = EIRP[dBm] + 95.2, E[dBµV/m] – 95.2 – Ant Gain = Corrected Data Frequency Measurement Corrected Data Criteria (MHz) (dBuV) (dBm) (dBm) 2402 94.19 -3.01 8.0 2442 91.09 -6.11 8.0 2480 90.92 -6.28 8.0 Result The maximum average power spectral density was less than the limit of 8 dBm; therefore, the EUT complies with the specification.
