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

17 = Distant End ReBalance failed

18 = Distant End NoResponse

19 = Fail-Calculate Mismatch

20 = CnC Ratio too high

21 = Please run again

22 = APC is active

23 = Local margin too low

24 = Distant margin too low

25 = Rx Data Rate<64kbps

26 = Tx Data Rate<64kbps

27 = Local RSL too low

28 = Distant RSL too low
