1. Purpose of Antenna System Sweep Testing Today’s digital wireless communication systems require a much more rigorous component and system specification as compared to previous analog systems. Consequently, there is a need for high performance testing.

Antenna system sweeps are an invaluable tool that is used to identify cable, connector, transient voltage surge suppressor (TVSS) and antenna problems, or degradations to the complete antenna system: GPS, LMU, AOA, or BTS paths. A complete antenna system includes the components of the base station site that lie between the base station equipment up to and including the antenna.

On newly installed sites, system sweeps are used to measure the quality of the installation and identify or resolve any issues before a site is allowed to carry public traffic.

Note: A new antenna is assumed to work correctly out of the box. If there is any concern regarding the antenna functionality, a separate antenna only test is provided.

On existing sites, antenna sweeps are important from a preventive maintenance perspective. Scheduled site antenna system sweeps can help to identify any adverse changes in the antenna system before customers are impacted.




2. Antenna System Testing Process To assist in the understanding of this suite of tests, a high-level process flow is provided. Figure 1 illustrates the typical steps to qualify and quantify a complete antenna system. A new BTS antenna system, LMU and AOA configuration will require all five main tests while existing antenna systems and GPS configurations require less as detailed in Section 3.

3. Antenna System Test Sceniros The purpose is to provide guidance required when performing sweep tests for New, Existing, LMU, GPS, or AOA Antenna Systems.

3.1 New Antenna System Perform sweep test Section 5.2 and Section 5.4 through Section 5.7 at the appropriate frequency band, Table 2 or Table 3. Complete BTS Antenna System Site Submission Form.

The results of sweep tests shall be provided to AWS, or AWS’s authorized representative, as part of the site turnover documentation in accordance with Section 6.

3.2 Existing Antenna System Refer to Appendix C - Section 9. Complete BTS Antenna System Site Submission Form.


3.3 LMU Antenna System Perform sweep test Section 5.2 and Section 5.4 through Section 5.7 at the appropriate frequency band, Table 2 or Table 3. Complete GPS/LMU Antenna System Site Submission Form.





3.4 GPS Antenna System Perform sweep test Section 5.2, Section 5.4, and Section 5.5 at the appropriate GPS frequency range, Table 4. Complete GPS/LMU Antenna System Site Submission Form.


3.5 AOA Antenna System Perform sweep test Section 5.2 and Section 5.4 through Section 5.7 at the appropriate frequency band, Table 2 or Table 3. Complete AOA Antenna System Site Submission Form.

Note: Bypass the Calibration Splitter for all Calibration Antenna System tests.





4. Tools and Equipment There are several manufacturers for spectrum and network analyzers. AT&T Wireless will not disqualify any manufacturer nor sweep testing results that are completed using equipment other than what is outlined in this standard document. Currently, this document recommends the use of either the S331/332 A/B/C, S235/251 A/B/C, S400A SiteMaster® models manufactured by Anritsu, Inc. (formerly Wiltron).

Other equipment required to complete the sweep tests:

• Precision 7/16 DIN 50 Ω Open/Short/Load

• One 7/16 DIN (or N) male-to-female adapter

• One 7/16 DIN female-to-female adapter

• Two-way radio for communication between the testing technicians located at the top of the antenna support structure and at the testing point

• 10’-0” long, ½”diameter coax jumper with one 7/16 DIN male connector located at each end of the jumper. (This is only required if the bottom jumper is not already installed into the antenna feedline system.)

• Connector torque wrench, i.e. Andrew Part#: 244377

Test equipment shall be allowed to stabilize in test environment prior to calibration for a minimum of thirty minutes, and shall be recalibrated at a minimum of every two hours and after any change in environment, to ensure accuracy.

NOTE: ENSURE ALL CALIBRATION EQUIPMENT IS CLEAN AND VOID OF ANY DEBRIS OR ANY OBVIOUS SIGNS OF MECHANICAL DAMAGE OR DEFECTS.

CAUTION: IT IS REQUIRED THAT ALL SITEMASTER® & LOAD EQUIPMENT BE CERTIFIED AND VERIFIED BY AN AUTHORIZED CALIBRATION FACILITY ON AN ANNUAL BASIS. IF REQUESTED, PROOF OF CALIBRATION SHALL BE SUBMITTED TO AWS OR AWS’s DESIGNATED REPRESENTATIVE.




5. Antenna System Test Cases

5.1 Return Loss of Antenna: Verify Antenna Quality This step is strongly recommended for all antennas, but only required to verify the quality of a reused antenna that is being installed. By testing all antennas before mounting onto the antenna support structure eliminates any possibility of rework and cost that may occur due to a faulty antenna.

1. Configure the SiteMaster® for RETURN LOSS by either recalling the saved Return Loss Setup for the frequency band of interest or performing the steps outlined in Section 8.1.

2. Set LIMIT LINE based upon antenna type, Table 1.

Table 1: Antennas – Loss Value Limit

Antenna Type Return Loss Frequency Range

Omni & AOA -14 dB 824 MHz – 892 MHz

or

1850 MHz – 1975 MHz

Cellular Panel -16.5 dB 824 MHz – 892 MHz

PCS Panel -17 dB 1850 MHz – 1975 MHz

UMTS/PCS Panel -15 dB 1710 MHz – 2150 MHz

3. Verify CAL ON is displayed at top left of display.

4. For Panels, ensure that antenna is elevated at least 3’-0” above the ground, away from any metalic objects and in a face-up position. For optimal results when positioning Omnis, place antenna in a vertical orientation clear of any obstacles.

5. Locate the peaks across the entire manufactureres band (between M1 & M2 receive and M3 & M4 transmit) and verify that the sweep in these bands are below the return loss value limit line defined in Table 1.

6. Verify all antennas are acceptable prior to installation.

Note: If the equipment jumper is not already installed, configure a 10 ft. jumper and connect it to the input of the TVSS unit.

The Main Feedline System is defined as the Equipment Jumper (less any diplexers or duplexers), TVSS device, Main Feed Line, Feed Line Jumper, MHA Bypass Adapter (if applicable), and Top Jumper.

We recommend using an ohm meter to verify the lines are correct.


Note: Every effort should be used to limit the use of adapters, however, if it is unavoidable, adapters should be high quality, and where possible, included in the calibration so that when calibration is completed, the calibration point will connect directly to the device under test.

If an adapter is required for calibration, THE ADAPTER CAN NEVER BE REMOVED FROM THE EQUIPMENT UNLESS A NEW CALIBRATION IS PERFORMED.


3. Perform RETURN LOSS with a 50Ω LOAD.

4. Set the LIMIT to –20 dB across the entire display range.

5. Place the 50Ω LOAD (same one used for calibration) at the end of the ANTENNA TOP JUMPER (if Mast Head Amplifier/Mast Amplifier Unit (MHA/MAU) is installed, by-pass MHA/MAU with 7/16 DIN female-to-female




adapter) and measure RETURN LOSS.

6. If the value is above the –20 dB limit line anywhere across the sweep range, use the DISTANCE-TO-FAULT, Section 5.3 as a troubleshooting aid to identify the questionable component and repair or replace as necessary. Remeasure RETURN LOSS and verify the reading is below the –20 dB limit line across the entire sweep range.

7. Using marker function place M2 to peak.

8. SAVE THE DISPLAY to memory and record PEAK value of M2 on Antenna Feedline System Site Submission Form.

2. Using DTF AID verify:

a. CABLE type is correct (predominant cable type installed).

b. D1 and D2 (D2 should be set to at least 20% greater than the maximum line length to test).

c. RESOLUTION is set to 130 points Greater than 300 ft. RES=517 pts.

d. Select CALIBRATION VALID from display and press ENTER.

3. Set the LIMIT to –25 dB across the entire display range.

4. If the value is above the –25 dB limit line anywhere across the sweep range, identify the questionable component and repair or replace as necessary.

5. SAVE THE DISPLAY to memory.

9. Appendix C: Existing System - Sweep Test M&P’s The purpose of Appendix C is to provide guidance required when performing sweep tests at sites where existing coaxial cable is re-used for new technologies or where complete antenna systems are reconfigured for new technologies.

9.1 Pre-Sweep Requirements Prior to performing any work on existing cables used for new technologies, or for reconfiguration of the existing technologies antenna system, a pre-sweep test shall be performed. The results of the pre-sweep can then be used to:

• Verify and document the condition of the existing antenna system. • Determine the necessity of any corrective action required on the antenna

system that may be required, such as replacement of connectors.

All pre-sweep tests shall be performed at the frequency of the existing antenna system.

The results of all pre-sweep tests shall be provided to AWS, or AWS’s authorized representative, as part of the site turnover documentation in accordance with Section 6.

9.2 Pre-Sweep Without Planned Tower Top Work

At sites where there is no requirement for tower top work such as antenna replacement, addition of MHA/MAU, or diplexers, the pre-sweep test shall be performed in accordance with Section 5.6 and Section 5.7 at the frequency band of intended use, Table 2 or Table 3.

9.2.1 Free Up Complete Antenna System Perform a pre-sweep test on the existing antenna system to be duplexed at

the appropriate band.

If the pre-sweep test does not meet the pass/fail limits as established in Section 5.6, the tester shall perform a distance to fault test in accordance with Section 5.7.

The distance to fault test results shall then be used to determine the component within the system where the fault exists. The following criteria




shall be used as a guideline to determine the requirement:

1. If bottom-side jumper, connector or TVSS are the source of the fault, they shall be replaced.

2. If the main coaxial cable, or topside jumper, connector or antenna is the source of the fault, notify AWS or AWS’s authorized representative of the fault. The bottom-side reconfiguration work shall continue as planned.

A post sweep test shall then be performed with the duplexer in line, Figure 12. A complete system sweep must be preformed at both equipment connections, Tx connection point and Rx connection point, in accordance with Section 5.6 and Section 5.7. The post sweep test shall be no worse than the standard outlined in Section 5.6 or –1.0 dB worse than what was recorded in the pre-sweep test. If the post sweep test fails to meet the criteria and is due to the main coax or topside components, notify AWS that the system does not meet the minimum requirement. If the post sweep failure is at the bottom, corrective action must be taken and a re-sweep performed.

9.2.2 Re-Use Complete Antenna System

Perform a pre-sweep test on the existing antenna system to be used at the appropriate frequency band.


The distance to fault test results shall then be used to determine the component within the system where the fault exists. The following criteria shall be used as a guideline to determine the site requirements:

1. If bottom-side jumper, connector or TVSS are the source of the fault, they shall be replaced.

2. If top-side jumper, connector, or antenna is the source of the fault, and the pre-sweep test was no worse than the pass/fail limit, proceed with the work and notify AWS or AWS’s authorized representative that the antenna system does not meet the requirements. Tower top work may be required to correct the fault at the direction of AWS.

3. If main coaxial cable is the source of the fault, notify AWS or AWS’s authorized representative of the fault. The main coaxial cable may be replaced, with AWS approval.

Prior to the installation of any new jumper cables each shall be sweep tested in accordance with Section 5.8.

After the work has been completed a post sweep test shall then be performed in accordance with Section 5.6 and Section 5.7.

9.3 Pre-Sweep With Planned Tower Top Work At sites where there is planned tower top work such as antenna replacement, addition of MHA/MAUs or Diplexers, the pre-sweep test shall be performed in accordance with Section 5.6.

The pre-sweep test shall be performed prior to completing any tower top work.




9.3.1 Free Up Complete Antenna System Perform a pre-sweep test on the cable(s) to be duplexed.



1. If bottom-side jumper, connector or TVSS, is the source of the fault, it shall be replaced.

2. If top-side jumper, connector, is the source of the fault, replace the defective jumper or connector

3. If the existing TDMA antenna is the source of the fault, proceed with the work and notify AWS or AWS’s authorized representative that the TDMA antenna does not meet the requirement. The TDMA antenna may be replaced to correct the fault at the direction of AWS.

4. If main coaxial cable is the source of the fault, notify AWS or AWS’s authorized representative of the fault. The main coaxial cable may be replaced, with AWS approval.

Prior to the installation of any new jumper cables, duplexers, or diplexers, each of the individual components shall be sweep tested in accordance with Section 5.8 and Section 5.9.

A post sweep test shall be performed with the duplexer and diplexers in line, Figure 13. A complete system sweep must be preformed at all three equipment connections using the appropriate frequencies, Frequency 1 Tx/Rx connection point, Frequency 2 Tx connection point and Frequency 2 Rx connection point, in accordance with Section 5.6 and Section 5.7. The post sweep test shall be no worse than the standard outlined in Section 5.6 or –1.0 dB worse than what was recorded in the pre-sweep test.
