Figure 9 shows the TRACER 6420 RF Link Max/Min Received Power History page, which displays the
available received power statistics from the system. Minimum and maximum received signal levels for the
RF link (from both the local and remote TRACER 6420 units) in 15-minute and 24-hour increments are
found on this screen.

Figure 9. RF Link Max/Min Received Power History

The received power level (

MIN

and

MAX

) represents the minimum and maximum values of received signal

level in a 24-hour or 15-minute increment and is displayed as a numerical value from 0 to 100, with 0
corresponding to 0 V of RSSI and 100 corresponding to 5 V RSSI.

The minimum receive power level is recorded to aid in troubleshooting problem RF links.
Radio links with high

MIN

numbers and intermittent performance are probably

experiencing interference, while links with low

MIN

numbers have improperly engineered

paths or excess system losses. A system with

MIN

numbers varying widely could indicate

fading, reflections, or an intermittent installation problem such as loose connectors,
damaged coax or lightning arrestors, or water contaminated feedlines.
