reset

A Boolean or a Boolean array that determines whether to set triggered to False and store the current trigger signal.

True Sets triggered to False and stores the current trigger signal.
False Does not set triggered to False or store the current trigger signal.

Default: False

trigger signal

Input signal.

This input accepts a double-precision, floating-point number or an array of double-precision, floating-point numbers.

datatype_icon

trigger type

Type of changes to the input signal that sets triggered to True.

This input accepts a ring or an array of rings.

Name Value Description
rising 0 Sets triggered to True when the input signal crosses threshold on a rising slope.
falling 1 Sets triggered to True when the input signal crosses threshold on a falling slope.
either 2 Sets triggered to True when the input signal crosses threshold on either a rising or a falling slope.

Default: rising

threshold

Threshold to start the measurement.

This input accepts a double-precision, floating-point number or an array of double-precision, floating-point numbers.

Default: 0
