Installation Guide

Sweep Range: 902 - 928 MHz
Markers: M1 - 902 MHz, M2 – 928 MHz
Insertion Loss Tests: Perform with test equipment connected to bottom jumper, and calibrated
short at the top jumper. The purpose of this test is to verify that insertion loss is within acceptable
limits.
Insertion Loss Test Parameters:
Sweep Range: 902 - 928 MHz
Markers: M1 - Peak R/L, M2 - Valley R/L
Passing is determined by comparing measured insesrtion loss to the calculated
insertion loss. Results should be no more than 1 dB over the calculated loss.
Load Test: Performed with test equipment connected to bottom of coax, and precision 50 Ohm
load terminated at top of the jumper. The purpose of this test to verify the coax meets the
manufacturer’s specifications.
Load Test Parameters
Sweep Range: 902 - 928 MHz Markers: M1 -Peak R/L
Passing is determined by the manufacturer’s specifications for the type of coax
being tested. Results should be as good as or better than the manufacturer’s
specification.
DTF Test: Performed with test equipment connected to bottom of coax, and top of the coax with
a 50 ohm Load Test device attached. The purpose of this test is to confirm the line length of the
coax as well as verify each connection point location / distance.
DTF Test Parameters
Sweep Range: 902 - 928 MHz
Markers : M1 - Peak
Understanding Party Responsibilities
This section outlines how Itron's role differs from the supplier's role in conducting the Antenna
Line Sweeps procedure.
Itron’s Responsibilities
Itron is responsible for the following aspects of the test:
■
Physical verification of all network device installations, to confirm the supplier’s quality of the
installation work. The supplier should expect that representatives from both Itron and the
customer will be on site at several installations of each type of network device (if not more), to
