Bunch Phase - DLS-Controls-Private-org/MBF-docs GitHub Wiki

Measurement of bunch phase for LMBF mode. This shows the magnitude and phase of each bunch using the dual ADC inputs I and Q. This is only available in LMBF mode.

All PVs described here are prefixed with $(device):$(axis01), where $(axis01) is normally IQ.

Title	PV	Description
Bunch Magnitude	:ADC:MAGNITUDE	Magnitude of signal from each bunch, computed as the magnitude of the I and Q ADC signals.
Bunch Phase	:ADC:PHASE	For bunches with relative magnitude greater than the threshold, shows the bunch phase (relative to Q = 0°), for smaller bunches shows 0.
Mean magnitude	:ADC:MAGNITUDE_MEAN	Overall average of the bunch magnitudes.
Mean phase	:ADC:PHASE_MEAN	Phase of the bunch ensemble for bunches with relative magnitude greater than threshold.
Threshold	:ADC:THRESHOLD	Absolute magnitude threshold, the phases of bunches lower than this magnitude are ignored. Used to detect filled bunches.
