Response to
Query
BERT Result
in average
BER
N/A 9 bytes Query only.
Valid only in CDM-570A Compatible Mode (CMO=1).
Returns the value of the average BER in the form x.xxEsyyl, where:
First 8 bytes are the value.
Last byte is the indicator of Sync Loss. A ‘*’ in last byte means there was a loss
of pattern synchronization since last restart, but now is synchronized. A ‘_’
(space) in last byte means pattern synchronization is achieved.
Returns 999999999 if there’s no sync in BERT monitor.
Examples: <0/BRR?
1) >0/BRR=2.80E-07 (BER is 2.80 x 10 -7 , in sync)
2) >/BRR=3.40E-05* (BER is 3.40 x 10 -5 , and there was a Sync Loss)
N/A BRR? BRR=x.xxEsyyl
ACM
parameters
ACM= 4 bytes Command or Query.
Valid only in CDM-570A Compatible Mode (CMO=1).
Sets or returns ACM operating parameters in the form mMAT, where:
m=Minimum ModCod, range is 0 to 9, and A (for ModCod=10)or B (for
ModCod=11)
M= Minimum ModCod, range is 0 to 9, and A (for ModCod=10)or B (for
ModCod=11)
A= Defines action on remote demod unlock
0 = go to minimum Tx ModCod
1 = maintain Tx ModCod
T=Target Eb/No Margin, from 0 to 9 that is two times the Eb/No in dB (from
0.0dB to 4.5dB).
Example: <0/ACM=0B12 (Sets min ModCod to 0; max ModCod to 11; maintains
Tx ModCod when remote demod unlocks; sets Target Eb/No at 1.0dB.)

Arguments)
Configuration Load CLD= 1 byte Command only.
Directs the CDM570AL to retrieve a previously stored modem configuration from
the Configuration Memory location 0 through 9.
