| Select Characterization Panel | Pushbutton to open it in an embedded window OR script to do all of these steps... |
| Check that the SSA Drive Max is set to 0.8 & push the Go button | |
| If the task does not complete or completes with an error, lower the SSA Drive Max and re-run calibration. If it still does not complete, call... | |
| Once it's complete, PUSH the calculated SSA slope & SAVE |
Tune the Cavity to 1.3 GHz tab
| Instructions | Action Fields |
|---|---|
| Select Frequency Tune panel | Open embedded or start a script? |
| Select Chirp for RF mode. Set the drive level to 15% | script |
| Turn on the RF | script? |
| Open a striptool with the chirp detune and total steps | pushbutton or already have plot on the display |
| Record the cold landing frequency (the chirp detune) of the cavity in the elog | caget or a box showing the detune. Button to record value to a python variable for writing to CSV file. Button to stick in elog? |
| Open cavity overview waveforms display | button to open or already show the waveforms on display |
| Reset the total stepper motor steps | Show the total, provide the reset button |
| Set the stepper to 10000 steps (1E4). Click the right arrow. Verify that the detune amount moves toward zero. The calibration is approximately 10 Hz/step. If the detune increases, go 20000 steps with the left arrow and verify that the detune moves toward zero. If not, contact an expert. | |
| Move the stepper until the chirp detune is less than 5 Hz. Expect to move many millions of step.s Record the number of steps that is needed to get the cavity within 5 Hz detune. | Are we brave enough to have a script do this? |
| Set the piezo to enabled and dc mode | buttons or little script |
| Verify the piezo engagement by changing the DC offset voltage 5 volts and observing the cavity frequency changes by the expected amount (~100 Hz/volt) |
