25 3.8 Radiated Spurious Emissions Performance Criterion: Radiated spurious emissions which fall in the restricted bands must comply with the radiated emission limits specified in FCC 5.9(a) and Table 2 of IC RSS-. Test Results: Complies Test Details: Radiated spurious emission was performed from MHz to the tenth harmonics of the carrier. For each scan of radiated emission measurement, the procedures for maximizing emissions were followed. The EUT was rotated and antenna height was varied between m and 4 m in order to maximize the emission. Measurements in both horizontal and vertical polarities were made and the data was recorded. ll radiated emission measurements, up to 8 GHz, were performed at 3-meter distance between an antenna and the EUT. ll radiated emission measurements, above 8 GHz, were performed at 0.3-meter distance between an antenna and the EUT. The peak level of radiated emissions above GHz was measured with a resolution bandwidth (RBW) of MHz and a video bandwidth (VBW) of 3 MHz. For harmonics/spurs that fall in the restricted band, the radiated spurious emissions above GHz were measured with RBW of MHz, VBW of 0 Hz, and Sweep of uto. The unit was configured for continuous operation. EUT was tested in three orthogonal orientations (XY, YZ, and ZX planes). EUT = XY EUT = YZ EUT = ZX Refers to the following block diagram and data table for test data. ntenna factor, cable loss, and preamplifier gain were compensated for in the receiver. factor of db/decade applies to measurements made at a closer distance than the limit distance before comparing to the limits.

30 3.9 Receiver Radiated Emissions Performance Criterion: Receiver radiated emissions must meet the requirements of Table of IC RSS-Gen. Receivers operating above 9 MHz or below MHz are exempt from complying with the technical provisions of FCC Part 5 Subpart B. Test Results: Complies Test Details: Radiated emission was performed from MHz to the fifth harmonics of the carrier. For each scan of radiated emission measurement, the procedures for maximizing emissions were followed. The EUT was rotated and antenna height was varied between m and 4 m in order to maximize the emission. Measurements in both horizontal and vertical polarities were made and the data was recorded. ll radiated emission measurements, up to 8 GHz, were performed at 3-meter distance between an antenna and the EUT. For the measurement of radiated emission at the frequency range -000MHz, measurement was made by using a quasi-peak detector with a khz bandwidth. For the frequency range above GHz, measurement was made using an average detector with a MHz bandwidth. EUT was tested in three orthogonal orientations (XY, YZ, and ZX planes). EUT = XY EUT = YZ EUT = ZX Refers to the following block diagram, data table, and receiver screen captures for test data. ntenna factor, cable loss, and preamplifier gain were compensated for in the receiver.
