Query only.
Valid only in CDM-570A Compatible Mode (CMO=1).
Monitors the ratio, in dB, between the interferer and the desired power when CnC
is enabled and the modem is locked.
Examples: <0/CRM?
1) >0/CRM=+02 (interferer>desired) (format = sdd)
2) >0/CRM=LT11 (less than –11 dB)
3) >0/CRM=GT11 (greater than +11 dB)
4) >0/CRM=99.9 (not locked or CnC not enabled)
5) >0/CRM=AUTO (in CnC-APC mode)
Query only.
Valid only in CDM-570A Compatible Mode (CMO=1).
Monitors the delay, in microseconds, of the interferer when CnC is enabled and
the modem is locked.
Examples: <0/CDM?
1) >0/CDM=229500 (229.5 ms)
2) >0/CDM=999999 (not locked or CnC not enabled)
