Response to Query
CnC-APC Max
Power Level
Increase
APL= 3 bytes Command or Query.
CnC-APC maximum power level increase in the form x.x, range from 0.0 thru 9.9 dB, limited by Tx power level.
Example: <0/APL=3.9 (APC max power level increase is 3.9 dB.)

Arguments)
CnC-APC Home
State
AHS= 12 bytes Command or Query.
Command is only for Offline unit in Redundancy system, sent by 1:N switch or Online unit in 1:1 system.
Returns CnC-APC home state parameters in the form a,bbb,cc,ddd, where:
a=APC state: 1=APC is active, 0=APC is not active
bbb=APC home state Tx power, in 0.1dB. (minus sign assumed)
cc=APC home state max power level increase, in 0.1 dB.
ddd=APC Tx power threshold, in 0.1 dB. (minus sign assumed)
Example: <0/AHS=1,100,60,085 (APC is active, home state power is -10.0 dB, home state max power level increase is
6.0 dB, power threshold is -8.5 dB)

Arguments)
ACM Remote
Signal Noise Ratio
N/A 4 bytes Query only.
Returns the value of SNR of the remote demod in the form xx.x, where:
99.9=Demod is unlocked.
xx.x=Not in ACM.
Example: <0/RSN? >0/RSN=12.4
N/A RSN? RSN=xx.x
(see Description of
Arguments)
ACM Local Signal
Noise Ratio
N/A 4 bytes Query only.
Returns the value of Local Signal Noise Ratio in the form xx.x, where:
99.9=demod is unlocked.
xx.x=Not in ACM (resolution=0.1 dB)
Example: <0/SNR? >0/SNR=12.3 (indicates SNR @12.3 dB)
N/A SNR? SNR=xx.x
(see Description of
Arguments)
Uncorrected BER N/A 7 or 8 bytes Query only.
Units returns the value of the uncorrected BER.
LT=less than
GT=greater than
Returns 9999999 if the demodulator is unlocked or uncorrected BER data is unavailable.
Example: <0/BER? >0/BER=4.3E-02 or >0/BER=GT1.0E-1
N/A RBE? RBE=xxxxxxxx
