Misc. | CROSSING TIME

CROSSING TIME – [CROSST]
Output the time at which the signal cross the threshold, depending on direction and slope parameter.
CATEGORY
Miscellaneous

DESCRIPTION

The function outputs time value at which the signal cross the threshold, depending on direction and slope parameter. The scope of the search is limited to the window formed by Begin_Time and End_Time. Using HUGE for the End_Time will set the parameter to match the end of acquisition. If there is no match, the graphic will be empty.

Direction	Forward will search the threshold value from Begin_Time toward End_Time. Backward will do the opposite.
Slope	Using Positive Slope will search the threshold when the slope increase in function of time while Negative will search it when the slope decrease in function of time.

RESULT VARIABLES AND PARAMETERS

Result	Time at which the signal cross the threshold in function of the parameters
Signal	Input signal
Threshold	Reference value to which the signal is compared
Begin Time	Beginning time of the function
End Time	Ending time of the function
Direction	Direction for the search (1: Forward, 0 : Backward)
Slope	Type of slope (1: Positive, 0 : Negative)

SYNTAX
Result = crosst(Input,Threshold,T_Beg,T_End,Direction,Slope)

CHARACTERISTICS
Data type support

Double Floating point

EXAMPLE
Threshold = 0, T_Beg = 0, T_End = Huge
