SRU Installation 17286-1000 Rev. B 03/14/01 SRU Installation Manual 1-1 1. SRU Antenna Alignment 1.1 Introduction This chapter gives instructions for aligning the SRU antennas to the BRU for maximum signal strength. Before alignment of the antenna, perform the following steps: 1. Refer to “SAS Installation Manual” and perform the indicated procedures. Most of the principles used to locate a site for the Base Radio Unit can be applied to SRU placement. 2. Install the Base Station as explained in “BSIS Installation Manual.” 3. Install one or more Subscriber terminals as explained in “SAS Installation Manual.” 4. Install the Link Explorer PMP and configure the Base Station as explained in “BSIS Installation Manual.” The direction in which the SRU antenna points must be aligned to the location of the associated BRU to ensure that maximum received signal strength is achieved at both ends of the microwave link. Although the antenna radiation pattern is typically thought of as a “beam,” the radiation pattern actually consists of “lobes,” as shown in Figure 1-1. How you planned your network will help identify which specific antenna is used in this ST and the BRU for the link. SRU Installation SRU Installation Manual 17286-1000 Rev. B 03/14/01 1-2 1.2 SRU Alignment This chapter contains information about SRU alignment. 1.2.1 1.2.11.2.1 1.2.1 Preparation and Overview of Procedure Preparation and Overview of ProcedurePreparation and Overview of Procedure Preparation and Overview of Procedure It is recommended that a person be present at both the SRU and the associated BRU for this antenna alignment procedure. It is also advisable to have some form of communication between the two sites, such as cell phones, two-way radios or telephones. Mirrors or strobe lights (for flashing the path) are recommended for situations in which the antenna locations are not readily visible from one another, as a result of distance or atmospheric conditions. It is absolutely essential that there are no obstructions present in the path of the beam. The objective of this procedure is to aim the main lobe of the SRU antenna precisely in the direction of the associated BRU. This is accomplished by performing a rough visual alignment first; then further alignment is performed while monitoring the Receive Signal Level at the Subscriber Radio Unit with a voltmeter. The alignment process consists of adjusting the direction of the SRU until the received signal level is maximized. Do not confuse the alignment directions (horizontal, vertical - that is, azimuth, elevation) with the polarization of the antenna feed assembly. Antenna polarization should be established prior to installation. Verify that the polarization of the SRU matches the polarization of the BRU. Connect a Voltmeter to ensure that the SRU is getting power. A reading of zero means that there is a problem with the SRU, SAS, or cable (or voltmeter). A reading of +4.0 Volts indicates it is likely that the SAS is not admitting and is presently scanning through the channels of the channel plan as it attempts to admit. Or that the SAS cannot admit because Figure 1-1Antenna Pattern SRU Installation 17286-1000 Rev. B 03/14/01 SRU Installation Manual 1-3 the SRU is drastically out of alignment. Re-align the SRU visually and wait for it to re- admit. If the reading is between 0 Volts and 4 Volts, then the SAS has admitted. Tighten the lock nut/washers to eliminate most freeplay, but not so tight that you can’t move the SRU in both directions. During the rough alignment procedure (see below) the purpose is to align the SRU visually, both elevation and azimuth. If it is totally off-lobes it will read very high (and you’ll be able to see that it is not aligned). Attach the voltmeter. Adjust it visually in both dimensions to determine where the main lobe is centered. Adjust the azimuth for the maximum reading. Tighten the azimuth bolts bit by bit without losing the reading. Repeat for elevation. Remove the voltmeter and replace the hanging cap. The purpose of the fine alignment procedure (see below) is to achieve precise antenna alignment, which is critical for optimum system performance. Make sure the antenna is aligned on the main lobe as shown in Figure 1-2, this arrangement produces a significantly lower receive signal strength, making your system more vulnerable to outage due to fading. Parabolic antennas are highly directional (focused) and any movement of the antenna during alignment should be performed SLOWLY. This allows observation of the side and main lobes during antenna movement. It is important to verify that the SRU antenna is aligned to the MAIN LOBE. Figure 1-2 Correct Antenna Alignment SRU Installation SRU Installation Manual 17286-1000 Rev. B 03/14/01 1-4 Figure 1-3 Incorrect Antenna Alignment on a Sidelobe Typically, if your final receive signal level (RSL) is approximately 30 dB below the calculated value, the link is either aligned on a side lobe or the antenna polarizations are mismatched. 1.2.2 1.2.21.2.2 1.2.2 Alignment of SRU Alignment of SRUAlignment of SRU Alignment of SRU Before proceeding, verify that the antenna and mount have been properly assembled. Verify that both ends of the link are powered-up. 1.2.2.1 1.2.2.11.2.2.1 1.2.2.1 Azimuth Procedure Azimuth ProcedureAzimuth Procedure Azimuth Procedure To perform the rough azimuth alignment, complete the following steps: 1. Set the azimuth adjusting plate at roughly the middle of its range (centered) and lock it down. Have the person at the far end use a mirror or strobe light to make the opposite site more visible. If necessary, loosen (slightly) the pole mount brackets and rotate the antenna assembly on the mounting pole. If needed, the Voltmeter can be used now. 2. With the antenna pointed toward the BRU, slowly tighten the azimuth adjustment lock nut/washers. While tightening them, check to see that the antenna remains pointing directly at the other site.

Netro Corporation 39GHz Radio Operational Description The 39 GHz radio unit (RU) is comprised of three printed circuit assemblies (PCA) – power supply/microprocessor, IF module, and microwave module - a transmitter power amp, receiver low noise amp, and waveguide filter assembly. Refer to the block diagram. The microprocessor/power supply PCA utilizes a switch mode power supply built from discrete components and integrated circuits to convert the –48V nominal input voltage to +8V and –7V nominal output voltages. Power is distributed to the IF module PCA via a multipin connector. The microprocessor is an 8-bit microcontroller which runs a program stored in onboard FLASH memory. The microprocessor controls and monitors RU functions as well as provides communication with the indoor unit. The IF module PCA provides multiplexing and cable protection for the signals on the RU external TNC connector, IF gain control functions, IF filtering, and DC power distribution to the microwave module PCA. The multiplexer is a discrete component design that separates the –48V DC power, telemetry, frequency reference, 350 MHz transmit IF, and 140 MHz receive IF signals. The –48V DC and telemetry signals are routed to the microprocessor/power supply PCA via multipin connector. The reference frequency is fed to phase lock loop circuitry that generates the 12.5MHz reference frequency used by all phase lock loops in the RU and to the microwave module PCA via coaxial feedthrough. The 350 MHz transmitter IF signal is routed to AGC circuitry that provides a constant signal level into the upconverter mixer. The transmit IF mixer LO is generated from the diode-doubled output of a VCO that is phase locked to the 12.5 MHz reference signal. The LO synthesizer is capable of 625 kHz step size over the 1275 MHz to 1287.5 MHz frequency range. The upconverted and filtered transmit second IF signal is fed to the microwave module PCA via coaxial feedthrough. The receiver second IF signal comes from the microwave module PCA via coaxial feedthrough. The signal is filtered and downconverted to the 140 MHz receiver IF. The receive IF mixer LO is generated from the doubled output of a VCO that is phase locked to the 12.5 MHz reference signal. The LO synthesizer is capable of 1.25 MHz step size over the 2190 MHz to 2235 MHz frequency range. The 140 MHz receiver IF is passed through switched channel filters that provide channel bandwidth filtering. The filtered receive IF is then routed to AGC circuitry that provides a constant signal level at the RU external TNC connector. The microwave module PCA contains a VCO phase locked loop and times eight-diode multiplier chain. This synthesizer and multiplier chain produces the LO for transmit and receive frequency conversion. The LO is fed to the upconverter mixer where it is tripled and then mixed with the transmitter second IF signal resulting in the output transmit signal. The output transmit signal is filtered in the waveguide filter assembly then amplified by the transmitter power amp and filtered by the diplexer filter and routed to the antenna port. The transmit power amp is a thin-film amplifier module built with MMIC devices and is utilized in conjunction with gain control circuitry at the 350 MHz transmit IF for transmit power control. The receiver input signal is fed from the antenna port through the diplexer filter to the receiver low noise amplifier. The receiver LNA is a thin-film amplifier module built with MMIC devices. The output of the LNA is fed to the waveguide filter assembly and then to the microwave module PCA. The receiver input signal is then downconverted using the tripled LO signal to produce the receive second IF signal which is routed to the IF module PCA. The antenna assemblies vary dependent upon which model RU is built. Base radio units (BRU) with integral antennas utilize a waveguide sector horn antenna.
