Figure 10. RF Link Max/Min Received Power History
The received power level (
MIN
and
MAX
) represents the minimum and maximum values of received signal
levels in 24-hour or 15-minute increments, and is displayed as a numerical value in dBm.

Figure 10 on page 67 shows the TRACER 64x0 RF Link Min/Max Received Signal Quality History menu
page, which displays the available received signal quality statistics from the system. Minimum and
maximum received signal quality levels for the RF link (from both the local and remote TRACER 64x0
units) in 15-minute and 24-hour increments are found on this menu page.

Real-time signal values are not supported on all TRACER 64x0 systems. Systems must be
ADTRAN calibrated to provide readings for Rx or Tx Power signal levels. For
uncalibrated systems, the received power level is displayed as a numerical value from 0 to
100 where 0 corresponds to 0V RSSI and 100 corresponds to 5V RSSI.

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