Description of Arguments
Query only.
Unit returns the value of CnC-APC BER in the form ax10
First byte is the value, last two bytes are the exponent.
Returns 9999 if modem is not in CnC-APC mode or there is an APC frame sync error.
BER is measured in frame UW.
Example: ABE=8E-5
Command only.
Restart CnC-APC BER measurement.
Note: This command takes no arguments.
Query only.
Unit returns the value of CnC-APC FER in the form ax10
First byte is the value, last two bytes aret he exponent.
Returns 9999 if modem is not in CnC-APC mode or there is an APC frame sync error.
Example: Example: AFE=8E-2
Command only.
Restart CnC-APC FER measurement.
Note: This command takes no arguments.
Command only.
Used to activate or suspend APC operation, in format APC=x, where:
0 = no action
1 = Activate APC
2 = Suspend APC
Query only.
Unit returns the state of APC operation. Return value is in form xx, where:
00 = APC is not active
01 = No Solution
02 = OK - ReBalance Done
03 = OK(Partial) - CnC Ratio approaches limit
04 = OK(Partial) - Local power approaches miminum value (-25 dBm for IF band)
05 = OK(Partial) - Local power approaches minimum value (-40 dBm for L-Band)
06 = OK(Partial) - Local power approaches maximum value (0 dBm)
07 = OK(Partial) - Local power approaches limit set by max power level increase
08 = OK(Partial) - Distant power approaches miminum value (-25 dBm for IF band)
09 = OK(Partial) - Distant power approaches minimum value (-40 dBm for L-Band)
10 = OK(Partial) - Distant power approaches maximum value (0 dBm)
11 = OK(Partial) - Distant power approaches limit set by max power level increase
12 = OK(Partial) - Incomplete
13 = No APC Frame Sync
14 = CnC Ratio Problem
15 = Local EbNo too high
16 = Distant EbNo too high
