Antenna Line Sweeps Procedure
By combining Itron’s proven 915 MHz ER platform with fixed network technology and
software applications, Itron provides a suite of data collection technologies for electric, gas, and
water utilities. This fixed network solution, which is built upon our ChoiceConnect® system
architecture, enhances customer engagement, increases operational efficiencies, and ensures
system integrity.
The endpoints transmit to an Itron installed collection engine (data server) that is installed at the
customer site, via one of three Itron manufactured network devices: a ChoiceConnect Tower
Mounted Collector Unit (TCU 100), a ChoiceConnect Collector Unit (CCU 100) or a
ChoiceConnect Repeater Unit (Repeater 100).
A remote 915 MHz antenna can be configured instead of the standard vertically polarized
antenna that is directly attached to the CCU/Repeater. The remote configuration uses a
standard vertically polarized (5.15 dBi or 5.5 dBi) antenna that is connected remotely or a high-
gain vertically polarized remote antenna that is mounted remotely. See Antenna
Specifications on page 4 for antenna part numbers.
Remote antennas must be properly grounded using a lightning arrestor. Refer to Grounding
Specifications on page 104 for additional grounding information.
Anritsu Site Master Calibration
For the Antenna Line Sweeps procedure, Itron recommends using the Anritsu Site Master
S331E, but similar models can be used.
Setting up and Calibrating the Anritsu Site Master S331E
1. Set resolution to the maximum value (typical sweeps should be set to sweep values of 902-
928 MHz, with a propagation velocity of 0.8 and resolution of 517 points for the Anritsu Site
Master).
2. Ensure all cables and jumpers are in their permanent locations and positions. Hangers,
cable blocks, ground kits, and other hardware must be in place and connected using
industry-standard torque wrenches to meet specifications for connectors.
3. Allow the test equipment to stabilize for approximately 15 minutes before taking any
measurements.
4. Calibrate according to the manufactures instruction using a phase stable cable, precision 50
ohm load, open, and short circuit terminations.
