Note: Note Equipment must be calibrated per manufacturer suggested calibration
period. Record the test equipment manufacturer, model number, and calibration
expiration date on the Itron ChoiceConnect Antenna and Line Sweep Test Form on page
98.
The following illustration shows the Anritsu Site Master.
Testing on a Network Device with a Remotely-Mounted 915
MHz Antenna
When the 915 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.
