Radiated emissions measurements were performed on a three-meter open area test site (OATS).

The EUT with host external computer was configured for maximum signal gain and bandwidth. The EUT was operated in a manner representative of the typical usage of the equipment. During all testing, system components were manipulated within the confines of typical usage to maximize each emission. 5.0TEST TYPE(S) 5.1Radiated Emissions: 47 CFR 2.1053, 22.901(d)(2), 22.917(e) 5.2Occupied Bandwidth: 47 CFR 2.1049, Input vs. Output 5.3RF Power Output: 47 CFR 2.1046, 22.913(a) 5.4Spurious Emission at Antenna Terminals (uplink & downlink): 47 CFR 2.1051, 22.917(e) 5.5Intermodulation Spurious Emissions-3 Tone Simultaneous RF Injection (uplink & downlink): 47 CFR 2.1051, 22.917(e). 5.6AC Line Conducted Emissions: 47 CFR 15.107 E(V/m) 1m ' 49.2X4 1 E(V/m) 1m '14.0V/mor143dbμV 43%10Log(4)'49dB 143dBμV&49dB'94dBμV@1m E(V/m) 3m ' 49.2X4 3 E(V/m) 3m '4.67V/mor133.4dbμV 133.4&49'84.38dBμV@3m 6.0TEST RESULTS 6.1TEST TYPE: Radiated Emissions 6.1.1TECHNICAL SPECIFICATION:47 CFR 2.1053; 22.109(d); 22.917(e) 6.1.2TEST DATE(S):Sep.16, 1999 6.1.3MEASUREMENT PROCEDURES: As required by §2.1053, field strength of spurious radiation measurements were made in accordance with the general procedures of ANSI C63.4-1992 "Methods of Measurement of Radio-Noise Emissions from Low-Voltage Electrical and Electronic Equipment in the Range of 9kHz to 40 GHz". Preliminary radiated emission measurements were performed inside a shielded chamber with all digital signal generators on and terminated. The frequency list from the preliminary measurements was used as a guide for making final measurements on a 10 meter open area test site. The unit was scanned over the frequency range of 30MHz to 9 GHz. The Radiated Spurious Emissions Limit is obtained by the following: Based on an output power (as measured at the output of the Amplifier) of 4 watts: P o = 4 W As per 2.993 (a), it is assumed this power is to be fed to a half-wave tuned dipole. Using a conversion formula for distance, the field strength at one meter can be derived: As per 22.917(e), the spurious emissions must be attenuated by 43 + 10log(P) which is: Therefore, the limit for spurious emissions is: At 3 meters measurement distance, the limit is; According to 22.917(e), all signals must be attenuated by 49 dB. Therefore, the limit for spurious emissions for a test distance of 3 meters is: 6.1.4RESULTS: Carrier Emission:4 Watts FREQUENCY (MHz) EUT AZIMUTH (Degrees) ANTENNAEUT RADIATION (dBμV) ANTENNA FACTOR (dB/m) TEST DISTANCE (m) CABLE LOSS (dB) AMP GAIN MINUS FILTER LOSS (dBμV) FIELD STRENGTH (dBuV/m) LIMITS @ 3m (dBuV/m) POL (H/V) HGT (m) 41.10H221.212.031.2n/a34.484.38 41.145V1.522.910.831.2n/a34.984.38 206.290H2.521.717.932.7n/a42.384.38 206.290V1.522.…
