Cavity BPM systems work

• Hardware measurements (related to BPM design, systematics etc)
• Operations

Hardware measurements

1. Electronics gain (weekend measurement)
2. Calibration tone (continuous measurement)

Online measurements and tests

1. Individual BPM calibrations
2. Dynamic range, coupling strength (requires electronics gain), linearity
3. Cross coupling (x-y)
4. Resolution (simple, jitter removed)
5. Tone calibration system
6. Temperature monitoring system
