Report Number: ESTR0503-009 Dates: March 31, 2005 Page 5 of 33 FCC ID: STENRPCS20B EUT Type: RF Repeater (CDMA) 3. DESCRIPTION OF TEST 3.1 RF Power Output - The EUT is a bi-directional amplifier repeater on A-band frequency for broadband PCS. Downlink input (from Base station direction) is connected to a signal generator. Downlink output is connected spectrum analyzer through proper attenuator. The input to the amplifier is set such that the maximum power output is achieved at customer supplied antenna connector. The power measurement method of Uplink is also same way. 3.5 Occupied Bandwidth The signal (Down/Up) input is connected to the signal generator. The input to the amplifier is set such that the maximum power output is achieved at the customer supplied antenna connector (at the antenna connector of base station). Maximum Allowable Downlink Power Output is 40dBm and Maximum Allowable Uplink Power Output is 25dBm. The signal output is connected to the spectrum analyzer. The VBW is set to 3 times the RBW. The sweep time is coupled. 3.6 Spurious and Harmonic Emission at Antenna Terminal The various conducted spurious and harmonic frequencies is measured by means of a calibrated spectrum analyzer. The spectrum is scanned from the lowest frequency generated in the equipment up to 20GHz. Set the RES BW to 1% of the emission bandwidth to show compliance with the -13dBm, limit, in the 1MHz bands immediately outside and adjacent to the top and bottom edges of the frequency block. For the Out-of-Band measurements a 1MHz RBW was used to scan from 30MHz to 10xfo of the fundamental carrier for all frequency block. A display line was placed at -13dBm to show compliance for spurious, and harmonics. Inter-modulation Attenuation Test (2 Signal Method) Blocks Tested: A-B Downlink/Uplink Modulation Tested: Three input signals are chosen such that in the 15MHz channel blocks the lowest and second lowest channels are selected, and highest and second highest channels. 3.7 Radiation Spurious and Harmonic Emissions Radiation and harmonic emission are measured outdoors at our 3 meters test range. The equipment under test is placed on a wooden turntable 3 meters from the receive antenna. The receive antenna height and turntable rotations were adjusted for the highest reading on the receive spectrum analyzer. A half wave dipole was substituted in place of the EUT. This dipole antenna was driven by a signal generator with the level of the signal generator being adjusted to obtain the same receive spectrum analyzer reading. This level is recorded. For readings above 1GHz, the above procedure is rep…
