Piezo Pre-RF Check

SSA Characterization

Cavity Tuning

1. Enable the piezo (set ACCL:LXB:XXXX:PZT:ENABLE to 1)
   1. While it doesn't enable (while ACCL:LXB:XXXX:PZT:ENABLESTAT is not 1), toggle ENABLE to disabled (0) and enabled (1) again
2. Set the piezo to manual (set ACCL:LXB:XXXX:PZT:MODECTRL to 0)
   1. While it doesn't enable (while ACCL:LXB:XXXX:PZT:MODESTAT is not 0), toggle MODECTRL to feedback (1) and manual (0) again
3. Set the DC voltage offset (ACCL:LXB:XXXX:PZT:DAC_SP) to 0
4. Set the bias voltage (ACCL:LXB:XXXX:PZT:BIAS) to 25
5. Set the cavity drive level (ACCL:LXB:XXXX:SEL_ASET) to 15
6. Set the RF to chirp (set ACCL:LXB:XXXX:RFMODECTRL to 5)
7. Turn on SSA (set ACCL:LXB:XXXX:SSA:PowerOn to 1)
8. Wait for SSA to turn on (wait until ACCL:LXB:XXXX:SSA:StatusMsg is 3)
9. Reset cavity interlocks (set ACCL:LXB:XXXX:INTLK_RESET_ALL to 1) and wait 3s
   1. 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 9.b.i
      3. If the reset fails after 3 total attempts
         1. Throw an error
   2. If the reset succeeded (ACCL:LXB:XXXX:RFPERMIT is not 0)
      1. If the cavity isn't online (if ACCL:LXB:XXXX:HWMODE is not 0)
         1. Throw an error
      2. If the cavity is online (if ACCL:LXB:XXXX:HWMODE is 0)
         1. Turn on the RF (set ACCL:LXB:XXXX:RFCTRL to 1)
         2. Wait for the RF to turn on (wait while ACCL:LXB:XXXX:RFSTATE is not 1)
