Finds Signals in a waveform.
Analyzes a waveform and find signals using a constant fraction algorithm. It then does all the further analysis of the identified Signal.
This class will work on waveforms with a depth of 8 Bits.
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:
.../ConstantFraction/{AcqirisInstrument}
Acqiris Instrument that this channel is in:
.../ConstantFraction/{ChannelNumber}
Channel within the instrument (starts counting from 0)
.../ConstantFraction/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.
.../ConstantFraction/{Polarity}
the polarity of the signals that we are interested in:
.../ConstantFraction/{Threshold}
the theshold for the signals in Volts:
.../ConstantFraction/{Delay}
delay in ns used by the constant fraction method:
.../ConstantFraction/{Fraction}
fraction used by the constant fraction method:
.../ConstantFraction/{Walk}
walk of the Constant Fraction Discriminator in Volts

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.
| evt | The event from which we get the pointer to the channel. |
Implements cass::ACQIRIS::SignalExtractor.

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().
