Response to
Query
CnC Power Ratio
Monitor
N/A 6 bytes 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)
N/A CPR? CPR=xxxxxx
(see Description
of Arguments)
Carrier-in-Carrier
(CnC)
Re-Acquisition
Time
CRA= 3 bytes 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
CRA=
CRA?
CRA*
CRA#
CRA? CRA=xxx

Search Delay
CSD- 6 bytes 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
