Instructions for Viewing System FCC ID Label 1. Connect the RS-232 port on a laptop or other computer to the RS-232 serial console port of the BTS using a null modem cable. On the HP Proliant servers, the serial console port is located in the rear center of the server surrounded by a green label. The two figures below show the null modem cable connected to the serial console port on the HP Proliant server. Figure 1: Null modem cable connected to the serial console port of the HP Proliant server Figure 2: Close-up of a null modem cable connected to the serial console port of the HP Proliant server. 2. Turn on power to the BTS Server if it was turned off. Wait at least one minute for the server to finish booting. 3. Run a serial communications program such as HyperTerminal, bundled for free in Microsoft Windows systems, on the client laptop. Select to use the RS-232 port for communications (in HyperTerminal under Windows, this corresponds to selecting COM3 or another COM port in the initialization dialog box). Set the RS- 232 port to 115200 bits per second, 8 data bits, no parity bits, 1 stop bit, and hardware flow control. 4. Press the Enter key in the active HyperTerminal session. The BTS will respond by printing out identifying information and prompting for a login. A screen shot of an example HyperTerminal session is shown below.

This measures the occupied bandwidth at the absolute ends of this devices's frequency range. The max frequency drift measured over temperature was 700Hz. This amount of deviation will not move the 20dB down point outside of the 1930 to 1990 band this device operates in. The frequency drift measurement can be found in the Intertek Test Report #3082207.EMI-A pg 40.

The basic equation with a sample calculation is as follows: FS = RA + AF + CF - AG Where FS = Field Strength in dBμV/m RA = Receiver Amplitude (including preamplifier) in dBμV CF = Cable Attenuation Factor in dB AF = Antenna Factor in dB AG = Amplifier Gain in dB In the following table(s), the reading shown on the data table reflects the preamplifier gain. An example for the calculations in the following table is as follows. Assume a receiver reading of 52.0 dBμV is obtained. The antenna factor of 7.4 dB and cable factor of 1.6 dB is added. The amplifier gain of 29 dB is subtracted, giving a field strength of 32 dBμV/m. This value in dBμV/m was converted to its corresponding level in μV/m. RA = 52.0 dBμV AF = 7.4 dB/m CF = 1.6 dB AG = 29.0 dB FS = 32 dBμV/m Level in μV/m = [10( 32 dBμV/m)/20] = 39.8 μV/m The following is how net line-conducted readings were determined: NF = RF + LF + CF + AF Where NF = Net Reading in dBμV RF = Reading from receiver in dBμV LF = LISN Correction Factor in dB CF = Cable Correction Factor in dB AF = Attenuator Loss Factor in dB To convert from dBμV to μV or mV the following was used: UF = 10 (NF / 20) where UF = Net Reading in μV Example: NF = RF + LF + CF + AF = 28.5 + 0.2 + 0.4 + 20.0 = 49.1 dBμV UF = 10 (48.1 dBμV / 20) = 254 μV/m Emissions Report for Vanu, Inc. on the Model GSM 1900 Basestation Report Number 3082207.EMI-A Page 7 of 95 3.1 Measurement Uncertainty Compliance of the product is based on the measured value. However, the measurement uncertainty is included for informational purposes. The expanded uncertainty (k = 2) for radiated emissions from 30 to 1000 MHz has been determined to be: ±…
