YES

 

Carrier locked

 

 

 

 

 

NO

 

Carrier not locked

 

 

 

PCR Lock

Indicates whether the in-band receiver is locked to the current

 

program clock reference for a digital video service on the specified

 

tuner. If a digital carrier is not present, it indicates the PCR is not

 

locked.

In-band data not detected within the last 5 seconds

 

 

 

Frequency

The in-band frequency is center RF carrier frequency tuned for the

 

digital service on the specified tuner. The frequency is displayed in

 

MHz in xxxx.xxx format and ranges from 54 to 860 MHz.

 

 

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

 

 

5 Second Error Counts

Indicates the number of correctable and uncorrectable digital multiplex

 

errors, up to 9999. It is updated every 5 seconds and reset each time

 

the DCX3200 is power cycled or another digital multiplex is tuned. The

 

maximum value displayed is 9999, even if there were more than 9999

 

errors.
