GUI Procedure

Piezo Pre-RF Check

  1. Turn cavity off
  2. Enable piezo (set ACCL:LXB:XXXX:PZT:ENABLE to 1)
  3. Set piezo to manual (set ACCL:LXB:XXXX:PZT:MODECTRL to 0)
  4. Set piezo DC voltage (ACCL:LXB:XXXX:PZT:DAC_SP) to 0
  5. Star the piezo pre rf test (set ACCL:LXB:XXXX:PZT:TESTSTRT to 1)
  6. Wait for the piezo pre rf test to finish (wait while ACCL:LXB:XXXX:PZT:TESTSTS is 2)
  7. Check test result
    1. If the test was not successful (ACCL:LXB:XXXX:PZT:TESTSTS is not 1)
      1. throw an error
    2. If the test was successful
      1. Check if chain A passed (ACCL:LXB:XXXX:PZT:CHA_TESTSTAT is 0)
      2. Check if chain B passed (ACCL:LXB:XXXX:PZT:CHB_TESTSTAT is 0)
      3. If either chain didn't pass
        1. throw an error
      4. If both chains passed
        1. Record piezo capacitance A (ACCL:LXB:XXXX:PZT:CHA_C)
        2. Record piezo capacitance B (ACCL:LXB:XXXX:PZT:CHB_C)
