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 Provider ID Displays the conditional access stream for the DCT3412, in hexadecimal
EMM PID Displays the packet identifier (PID) stream the DCT3412 tunes to for EMM data, in
hexadecimal
Network PID Displays the network PID to which the DCT3412 is tuned to receive network messages, in
hexadecimal
d04 In-Band Status
This diagnostic displays the in-band status for the last attempted tuned channel. The
information is updated every 5 seconds.
