class apstools.synApps.calcout.UserCalcoutN(prefix='', *, name, kind=None, read_attrs=None, configuration_attrs=None, parent=None, child_name_separator='_', connection_timeout=<object object>, **kwargs)[source]#: Single instance of the userCalcoutN database.

apstools.synApps.calcout.setup_gaussian_calcout(calcout, ref_signal, center=0, width=1, scale=1, noise=0.05)[source]#

setup calcout for noisy Gaussian

calculation:

D*(0.95+E*RNDM)/exp(((A-B)/C)^2)

PARAMETERS

calcout: object : instance of CalcoutRecord
ref_signal: object : instance of EpicsSignal used as A
center: float : EPICS record field B, default = 0
width: float : EPICS record field C, default = 1
scale: float : EPICS record field D, default = 1
noise: float : EPICS record field E, default = 0.05

apstools.synApps.calcout.setup_incrementer_calcout(calcout, scan=None, limit=100000)[source]#

setup calcout record as an incrementer

PARAMETERS

calcout: object : instance of CalcoutRecord
scan: text or int or None : any of the EPICS record .SCAN values, or the index number of the value, set to default if None, default: .1 second
limit: int or None : set the incrementer back to zero when this number is reached (or passed), default: 100000

apstools.synApps.calcout.setup_lorentzian_calcout(calcout, ref_signal, center=0, width=1, scale=1, noise=0.05)[source]#

setup calcout record for noisy Lorentzian

calculation:

D*(0.95+E*RNDM)/(1+((A-B)/C)^2)

PARAMETERS

calcout: object : instance of CalcoutRecord
ref_signal: object : instance of EpicsSignal used as A
center: float : EPICS record field B, default = 0
width: float : EPICS record field C, default = 1
scale: float : EPICS record field D, default = 1
noise: float : EPICS record field E, default = 0.05
