TDC-0971-011 CCU 100 and Repeater 100 Installation Guide 83
Proprietary and Confidential
By combining Itron’s proven 900MHz ERT® 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 900 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 antenna (MSE-0330-001 – Standard 5dBi antenna – Antenna
Products 1009-0066-403) that is connected remotely or a high-gain vertically polarized
remote antenna (MSE -0372-001 – Hi Gain 8.15 dBi antenna – Laird FG9026) that is
mounted remotely.
Remote antennas must be properly grounded using a lightning arrestor. Refer to Appendix
Grounding Specifications on page 93 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.
To set up and calibrate 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.
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 88.
