Negative Width VI

Owning Palette: Timing VIs

Requires: Jitter Analysis Toolkit

Measures the pulse duration that follows the level crossing in each falling transition.

	level crossings contains information about the locations of level crossings in the original waveform. You can use the Level Crossing VI to generate this cluster. t0 specifies the time at which the first sample occurs in the original waveform. dt specifies the time interval in seconds between the individual samples in the original waveform. indexes contains the index numbers of the samples in the waveform with values that fall at the crossing level. slope identifies the direction of the first transition in the waveform. -1 Falling Edge—Specifies the transition is a falling edge, or one with a negative slope. 1 Rising Edge (default)—Specifies the transition is a rising edge, or one with a positive slope. crossing level specifies the value of the waveform at each of the samples in indexes.
	error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
	- width sequence returns an array of the time differences in seconds between the time the signal falls below the crossing level and the time at which the signal next rises above that level.
	- width timestamps returns timing information about the waveform that allows you to identify the times at which measurements in the corresponding sequence occurred. t0 returns the time at which the first sample occurred in the original waveform. dt returns the time interval in seconds between the individual samples in the original waveform. indexes contains the index numbers of waveform samples that fall on the crossing level in falling edges of cycles that later rise above the crossing level.
	error out contains error information. This output provides standard error out functionality.
