SSA Characterization

Set the SSA drive max (ACCL:LXB:XXXX:SSA:DRV_MAX_REQ) to:
1. 1 If harmonic linearizer
2. 0.8 if not harmonic linearizer
Reset SSA interlocks (set ACCL:LXB:XXXX:SSA:FaultReset to 1)
Wait for the faults to reset (wait while ACCL:LXB:XXXX:SSA:StatusMsg is 4)
if ACCL:LXB:XXXX:SSA:StatusMsg is either 1 or 7:
1. Raise an error
if ACCL:LXB:XXXX:SSA:StatusMsg is neither 1 nor 7:
1. Turn on SSA (set ACCL:LXB:XXXX:SSA:PowerOn to 1)
2. Wait for SSA to turn on (wait until ACCL:LXB:XXXX:SSA:StatusMsg is 3)
3. Reset cavity interlocks (set ACCL:LXB:XXXX:INTLK_RESET_ALL to 1) and wait 3s
4. If the reset failed (ACCL:LXB:XXXX:RFPERMIT is 0)
  1. Retry up to 2 more times
  2. If the reset succeed within 3 total attemps
    1. Continue to step 5.e.i
  3. If the reset fails after 3 total attempts
    1. Throw an error
5. If the reset succeeded (ACCL:LXB:XXXX:RFPERMIT is not 0)
  1. Start the calibration (set ACCL:LXB:XXXX:SSA:CALSTRT to 1)
  2. Wait for the calibration to stop running (wait while ACCL:LXB:XXXX:SSA:CALSTS is 2)
  3. If the calibration crashed (if ACCL:LXB:XXXX:SSA:CALSTS is 0)
    1. Throw an error
  4. If the calibration succeeded (if ACCL:LXB:XXXX:SSA:CALSTS is not 0)
    1. If result is not good (if ACCL:LXB:XXXX:SSA:CALSTAT is not 0)
      1. Throw an error
    2. If the result is good (if ACCL:LXB:XXXX:SSA:CALSTAT is 0)
      1. If the max forward power (ACCL:LXB:XXXX:SSA:CALPWR) is below 3000
        Throw an error
      2. If the max forward power (ACCL:LXB:XXXX:SSA:CALPWR) is above 3000
        If the measured slope (ACCL:LXB:XXXX:SSA:SLOPE_NEW) is not between 0.5 and 1.6
        Throw an error
        If the measured slope (ACCL:LXB:XXXX:SSA:SLOPE_NEW) is between 0.5 and 1.6
        Push the SSA slope (set ACCL:LXB:XXXX:PUSH_SSA_SLOPE.PROC to 1)
        Save the SSA slope (set ACCL:LXB:XXXX:SAVE_SSA_SLOPE.PROC to 1)
