- Amplitude and phase stability of the S-band RF at the output of the LINAC (Accelerating Section 2)
RF Power Levels
...
- All data stored here
- Time estimate - request 4 hrs for margin
- Peak power measurements: 0.5 hr
- Scope measurement:
- Validate trigger: 0.5 hr
- Waveform alignment: 0.5 hr
- Take data, moving cart with scope around, capturing overlays: 1 hr
- TODO: add desired timing overlay captures
- Restore all cables and confirm normal operation
- TODO: confirm all cables installed; has cable 107 been replaced?

LINAC Stability
- Disconnect SMA10B SMA100B MO output
- Replace with FSWP Reference output
- Use LMX1214 frequency divider to divide the 2,997.8 MHz signal back to 499.634 MHz MO reference
- Measure phase and amplitude additive noise
- Time estimate: 3 hr
- Disconnect MO and confirm nominal operation with FSWP output as MO: 15 min
- Confirm pulsed RF signal on high speed scope: 30 min
- Measure additive and absolute amplitude and phase noise: 1 hr
- Restore all connections and confirm nominal operation: 30 min
- TODO:
- Lay down required cable runs and check losses
- Setup measurement infrastructure, power supply, cart, etc
