4 DIAGNOSTICS

Field

Description

 

 

SNR

When carrier lock has been established, displays an estimate of the carrier

 

signal-to-noise ratio in dB, with an explanation:

 

GOOD — Good value

 

FAIR — Marginal signal level, check the signal

 

POOR — Unusable signal

 

INVALID — Invalid SNR value

 

 

AGC

When carrier lock has been established, displays an estimate of the AGC as a

 

percentage, with an explanation:

 

GOOD — Good value

 

FAIR — Marginal signal level, check the signal

 

POOR — Unusable signal

 

INVALID — Invalid AGC value

 

 

EMM

Displays the conditional access stream for the DCX3200, in hexadecimal.

Provider ID

 

 

 

EMM PID

Displays the packet identifier (PID) stream the DCX3200 tunes to for EMM data,

 

in hexadecimal.

 

 

Network

Displays the network PID to which the DCX3200 is tuned to receive network

PID

messages, in hexadecimal.

 

 

Hunt Mode

The hunt mode includes Hunted, None, Round Robin (RR), Search (SRCH), Fixed

 

Frequency (FIX), or EMM Provider ID (EMM).

 

 

LKC

The last known carrier is the last valid OOB frequency displayed in MHz and

 

ranges from 70 to 130 MHz, with the specific values of: 75.25, 104.20, 72.75,

 

92.25, 98.25, 107.25, 107.40, 110.25, 116.25, and 103.75.

 

LKC will remain blank during hunting if a valid carrier has not been found, and

 

will be populated once a valid OOB is found.

 

 

Agile OOB Tuner Hunting

An OOB frequency can be selected manually by pressing the MENU button while in the OOB Status diagnostics screen. To exit this mode, press the MENU button a second time, or press the POWER button.

If the set-top is in the process of hunting for an OOB frequency, control of frequency selection is suspended, i.e. pressing Menu button on OOB status screen to display MAN FREQ is not available when the set-top is hunting.

Manual Selection of the OOB Frequency (OSD Frequency Override in Hunted Mode)

The manual override frequency capability is only displayed if the box is not currently hunting and the operator presses the MENU key while OOB OSD diagnostics are displayed. The MAN Freq displays the LKC and allows the operator to select (via scroll up/down) a specific frequency to check if a valid OOB is on that specific frequency. The MAN Freq parameter is the OOB frequency selected in the frequency selection mode and displayed in MHz, with the specific values of 75.25, 104.20, 72.75, 92.25, 98.25, 107.25, 107.40, 110.25, 116.25, and 103.75.
