5: The second AGC reading in case 2 or 4 above indicated
adjustment was required and the amount of excess attenuation
was 12 dB or more (for example, the cumulative amount of
attenuation decrease would be 24 dB or more). This can happen if
the signal path has excess loss. This case generates the
Downconverter Level Set Failed error message.
A is a number which represents the current Option 190 71.1 MHz
oscillator "state":

2: centered
3: upper
B is the character R if "RCVR CAL" is ON, r if it is OFF.
C is the character D if DSP based evm corrections are ON, d if they
are not.
D is the character E if DLP based evm corrections are ON, e if they
are not.
A typical readout of a −20 dBm, 8 MHz channel might be: 46 dB 80,2
