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: 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.
Antenna Return Loss Test: Complete a return loss test of the remote antenna on the ground
prior to installation. Determine the quality of the impedance match to 50-ohms at the antenna
connector. This test is performed with the test equipment calibrated for a one- port return loss
measurement to the end of the test cable. Ensure that the antenna is positioned vertically, at
least 24" above the ground, and at least 24" away from any metallic structure or equipment.
1. Configure the test equipment in return loss mode and calibrate.
2. Identify if the antenna passes or fails based on antenna manufactures specification. For
more information about the antenna specifications, see Itron ChoiceConnect 915 MHz
Antenna Specifications on page 99.
3. Save the trace for printing. This shall include site and sector numbers for identification.
System Test Parameters:
Sweep Range: 902 - 928 MHz
Markers: M1 - 902 MHz, M2 – 928 MHz
Overall System Return Loss Test: Sweep test of entire transmission system including:
antenna, coax, jumpers, and protection devices. Parameters of tests to be provided. While
monitoring the sweep results, move connectors on jumpers and coax to ensure all connections
are reliable. There should be no variance in sweep tests while stressing connections. The
purpose of this test is to ensure total system return loss is within acceptable limits.
1. Configure the test equipment in return loss mode and calibrate.
2. Identify if the system return loss passes or fails. The antenna specifications are attached to
this document as Attachment B.
3. Save the trace for printing. This shall include site and sector numbers for identification.
