Description of Arguments
Query
Query only.
When CnC is enabled and locked, the ratio between the interferer
and the desired signal power is readable in dB. The precision is
0.1 dB.
Example 1: CRM = +02.8 (interferer > desired)(format=sdd.d)
Example 2: CRM = LT10.0 (less than -10.0 dB)
Example 3: CRM = GT10.0 (greater than +10.0 dB)
Example 4: CRM = 9999.9 (not locked or CnC not enabled)
Command or Query.
CnC re-Acquisition time in seconds, from 10 to 999. This is the
time wherein CnC will start searching for the delay and frequency
offset if a long duration of unlock occurs.
Example: CRA = 010
Query only.
When CnC is enabled and locked, the ratio between the interferer
and the desired signal power is readable in dB.
Example 1: CRM = +02 (interferer > desired)
Example 2: CRM = LT10 (less than -10 dB)
Example 3: CRM = GT10 (greater than +10 dB)
Example 4: CRM = 99.9 (not locked or CnC not enabled)
Command or Query.
CnC min/max delay value in milliseconds, from 0 to 300 ms in the
form xxxyyy, where:
xxx = min delay
yyy = max delay
Example: CSD = 010300
