Interferer Test
The health of the network can be observed indirectly using commercial
off-the-shelf test equipment.
Tools Required:
• A portable spectrum analyzer with real-time signal capture.
Procedure:
1. Tune the spectrum analyzer to filter all unlicensed channels in the 450-470
MHz spectrum,
Or, place the spectrum analyzer in the waterfall mode and allow it to record
across the licensed frequencies.
2. Aclara RF Network I-210+c units typically report interval data every 15
minutes. Inbound traffic should be detected on one of the inbound channels
during this period.
3. Use the signal analyzer to record the signal strengths and your location.
If a strong transmission occurs which is not on a licensed channel, but
which bleeds over into the licensed area, this is evidence of a problem.
4. Take measurements for this meter at other locations as desired.
5. If a communication problem is believed to exist at the location, some
consultation with Aclara personnel may be necessary to identify a suitable
course of action.
Interference in a licensed band from a 3
rd
party may also require FCC
involvement (depending on the determination of the source of the problem.)
