Delay Monitor
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 (CnC not locked or CnC not enabled)
3) >0/CDM=888888 (In CnC mode, but Tx carrier is off)
(see Description of
Arguments)
Freq Offset
Monitor
Valid only in CDM-570A Compatible Mode (CMO=1).
Calculates an estimated frequency offset, in kHz, between the interferer and the
desired power when CnC is enabled.
Examples: <0/CFF?
1) >0/CFF=+001.0 (1 kHz)
2) >0/CFF=9999.9 (CnC not locked or CnC not enabled)
3) >0/CFF=8888.8 (In CnC mode, but Tx carrier is off)
(see Description of
Arguments)
Ratio Monitor
Valid only in CDM-570A Compatible Mode (CMO=1).
When CnC is enabled and the modem is locked, ratio (in dB) between the
interferer and the desired power is monitored, with 0.1dB resolution.
Examples: <0/CPR?
1) >0/CPR=+02.8 (interferer>desired) (format = sdd.d)
2) >0/CPR=LT11.0 (less than –11.0 dB)
3) >0/CPR=GT19.0 (greater than +19.0 dB)
4) >0/CPR=9999.9 (not locked or CnC not enabled)
5) >0/CPR=AUTO (in CnC-APC mode)
(see Description of
Arguments)
Valid only in CDM-570A Compatible Mode (CMO=1).
When CnC is enabled and the modem is locked, ratio (in dB) between the
interferer and the desired power is monitored, with 0.1 dB resolution.
Examples: <0/PSD?
1) >0/PSD=+02.8 (interferer>desired) (format = sdd.d)
2) >0/PSD=999.9 (not locked or CnC not enabled)
3) >0/PSD=AUTO (in CnC-APC mode)

Arguments)
