IPOC - FESA Main PropertiesLhcMkdIpocNi class:

Status get the system’s status and operating mode. Setting set the system’s operating mode. ReArm rearms the system in case of analysis error. Reset resets the system in case of hardware error.

Waveform get the acquired current waveform. IpocResults get the results of analysis & check.

TRIGGERED

ANALYZING

mode=ACQUIRING

ANALYZED ERRORANALYZED OK

ReArm()

ACQUIRING: Scope cards are acquiring. Beam injection permitted.

TRIGGERED: Read waveform from scope cards. Beam injection not permitted.

ANALYSING: Waveform available for XPOC. Performing waveform analysis.

ANALYSED_OK: No problem detected Can set mode = ACQUIRING

ANALYSED_ERROR: Tracking problem detected Must use ReArm property.

IPOC – Waveform Processing

RemoveOffset

RemoveNoise

CableCorrection

RAWWaveform

CableGain

FilteredWaveform

Removing of the offset to the waveform: Offset is computed from pre-trigger data.

Removing high frequency noise: 399 coefficients low-pass FIR filter (fc 2.5 MHz).

Correction of cable frequency response: 4 Second-Order-Section IIR filters.

Compensation of cable losses: Adjust the overall gain.

IPOC - Statuses & Alarms

Analysis check error:

Status = OK Alarm = WARNING

“IPOC check failed.”

Must use the ReArm property.

Hardware error:

Status = ERROR Alarm = ERROR

“Scope error occurred.”

Must use the Reset property.
