Appendix E Antenna Line Sweeps Procedure
The following illustration shows the Anritsu Site Master.
Testing on a Network Device with a Remotely-Mounted 900
MHz Antenna
When the 900 MHz antenna is remotely mounted, perform antenna and line sweeping
tests to verify that the transmission system functions within acceptable tolerances. While
monitoring sweep results, move all connectors on jumpers and coax to ensure all
connectors are properly installed and reliable.
Note There should be no variance in sweep tests while stressing
connections.
General Testing Conditions
Perform sweep testing under the following general testing conditions:
• Overall System Return Loss: Must be -14 dB or better for the specified frequency
band. Any deviations from this return loss warrant further investigation.
• VSWR Expected Results: 1.5 : 1 or less for the specified frequency band.
• Test Point: Feed line connected to the antenna at the top; test from the lightning (or
surge) arrestor to the antenna port.
• Results: Test results must be saved in PDF format.
• Test Equipment Requirements: Current and proper calibration; be sure that
calibration is turned on during the test. A qualified operator of the test equipment
must perform the test.
Note If the system does not perform to the above test specifications, the reasons for
system failure and possible remedies must be identified before leaving the site.
Specific Testing Conditions
Perform sweep testing under the following specific testing conditions:
Note Attach a copy of each trace to the antenna sweep checklist so that the
Itron Field Engineer can inspect and sign off on acceptable results.
