RESET: 0x00
Default R/W
Offset Address: 0x35
Bit
Name
Description
Bits 7:0 of SNR_CARRIER. The 13 bits of the SNR carrier
number specify which carrier’s SNR is output in the
CHC_SNR register allowing the SNR of each carrier to be
monitored.

Note: Once this register has been set then it may take up to
1 symbol (~1ms in 8K, ~0.25ms in 2K) for the CHC_SNR
register to contain the correct value.
SNR_CARRIER_2
Read/Write
Description
RESET: 0x80
Default R/W
Offset Address: 0x36
Bit
Name
If set, this outputs the means SNR of all the continuous
pilots in the CHC_SNR register, otherwise the SNR of the
specified carrier is output.

Default R/W
This value is the output of the PPM continuous pilot
correlator. During continuous pilot correlation, it holds the
peak detected value, at the end of scattered pilot
correlation shows the peak detected value, and during
normal operation shows a running measurement of the
continuous pilot correlation. A value below 20 (2K) or 80
(8K) indicates that the OFDM signal may have
disappeared, or is extremely noisy. A peak value of 42 or
176 (2K or 8K respectively) is attained with a perfect
signal.
