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