Detailed Description

Finds Signals in a waveform.

Analyzes a waveform and find signals when they have three consecutive points above the defined threshold. It then does all the further analysis of the identified Signal.

This class will work on waveforms when a datapoint depth of 8 bit is chosen

User settable parameters via CASS.ini:
One can set these parameters for each SignalProducer of the Detectortype. Therefore the settings will be for the the following signal producers:

• For MCP in Delayline and TofDetectors its :
  • AcqirisDetectors/detectorname%/MCP
• For Layer Wireends in Delaylinedetectors its:
  • AcqirisDetectors/detectorname%/Layername%/Wireendname%

User definable Parameters:

.../CenterOfMass/{AcqirisInstrument}
Acqiris Instrument that this channel is in:

• 8: Camp (Acqiris Multiinstrument with 5 Cards (20 Channels))
• 4: AMO I-ToF
• 5: AMO Magnetic Bottle
• 2: AMO Gas Detector

.../CenterOfMass/{ChannelNumber}
Channel within the instrument (starts counting from 0)

.../CenterOfMass/Timeranges/(0,1,...)/{LowerLimit|UpperLimit}
set of timeranges. One can set more than one range of interest. Default is no timerange, which will result in no signal will be found.

.../CenterOfMass/{Polarity}
the polarity of the signals that we are interested in:

• 1: Positive Polarity
• 2: Negative Polarity

.../CenterOfMass/{Threshold}
the theshold for the signals in Volts:

Note

we should let this class only identify the Signals and create the Signal list. The further analysis of the Signal should be done, when the user requests a property.

Member Function Documentation

void CoM8Bit::associate ( const CASSEvent &  evt )

virtual

associate the event with this analyzer

Extracts a pointer the channel for which we are there for from the event with the help of extractRightChannel.

Parameters

evt	The event from which we get the pointer to the channel.

void CoM8Bit::loadSettings ( CASSSettings &  s )

virtual

load the settings of the extractor

Calls the loadSettings implementation to retrieve all information to be able extract the signals from _channel. And to be able to extract the right channel from the events in associate().

Parameters

s	the CASSSettings object to retrieve the information from
