Diagnose RF Tuner Issues

The Device View > RF Tuners portlet displays RF Signal data and provide the tools to troubleshoot signal
problems. Here, you can gain a broad, but accurate, view of the current RF tuners' statuses and identify the
root cause of problems associated with tuning, frequency, or errors. In the History section, the tuners are
sampled every half an hour and when the subscriber changes TV channel.

The RF Tuners Overview displays the tuners in real-time with signal strength, quality and frequency for those
tuners that are locked into signals. Numbers displayed in red show that they are either below or above the
required threshold.

Note

OL-32174-01 1

The column heading Channel refers to a specific channel translated from the equivalent frequency. In
devices that do not support this feature, the column heading is displayed as Frequency.

Status

Represents a tuner:

in a 'locked' state (i.e. locked into a fixed signal)

not in use

in 'unlocked' status

with error status

Measured in dBm / dBuV/ dBmV (displayed when Tuner status is locked)Strength

Quality

Measured in bit error rate of the tuned signal, in errors per 10^-9 bits (displayed when
Tuner status is locked)

Quadrant

Displayed for supporting satellite devices only. Shows Vertical-Low (VL),
Vertical-High (VH), Horizontal-Low (HL), Horizontal-High (HH)

The Tuners section represents the ratio of failures to total samples for each tuner. These samples are taken
every 30 minutes and/or when the TV channel is changed over a period of three weeks maximum (or however
long is displayed in the History section of this portlet). Clicking on an individual tuner takes you to a graphical
representation of the results as shown in the History tab.

The Channel section (may be displayed as Frequency) displays the total percentage of RF Tuning failures
from highest to lowest according to the Frequency (Channel). Frequencies with ten or less samples are not
included in this list. Clicking on an individual channel takes you to a graphical representation of the results
as shown in the History tab.

DescriptionScreen Name

This screen displays the signal strength and quality for each tuner, plotted in a linear
progression over a three week period. The legend at the side shows you the color code
for each tuner and also enables you to filter the results per tuner. The search box at
the top enables you to filter the results according to specific items either in Time,
Tuner, or Frequency (Channel).

This screen displays the amount of errors or successes in the samples taken for each
frequency (channel).

This screen displays an in-depth view of the tuner and frequency statistics, breaking
errors down into four areas: Strength/Quality/Unlocked/Error. It also gives a total error
count at the end. Note that a failure might include errors from more than one category.

This screen displays RF signal strength and signal quality historical trend for each
quadrant (VL, VH, HL, HH). Displayed for supporting satellite devices only.
