Owning Palette: Single Tone Measurements VIs

Installed With: Sound and Vibration Measurement Suite

Computes the crosstalk from a stimulus signal to a response signal at the fundamental frequency and returns detected fundamental frequency, detected response amplitude, and crosstalk. The data types you wire to the stimulus signal X [EUx] and response signal Y [EUy] inputs determine the polymorphic instance to use.

Use the pull-down menu to select an instance of this VI.

SVT Crosstalk (Time)

	desired units specifies the engineering units of the returned measurements. crosstalk units specifies the units for crosstalk. 0 dB (default) 1 Linear ratio phase units specifies the units for phase measurements. 0 deg (default) 1 rad detected tone stimulus amplitude units specifies the units for the amplitude of the fundamental tone as measured on the stimulus channel. 0 EU rms (default) 1 EU peak 2 EU peak-peak detected tone response amplitude units specifies the units for the amplitude of the fundamental tone as measured on the response channel. 0 EU rms (default) 1 EU peak 2 EU peak-peak
	stimulus signal X contains the scaled signal acquired from the stimulus channel expressed in the selected engineering units.
	idle-channel response signal Y [EUy] contains the scaled signal acquired from the idle channel expressed in the selected engineering units.
	error in describes error conditions that occur before this VI or function runs. The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. This VI or function runs normally only if no error occurred before this VI or function runs. If an error occurs while this VI or function runs, it runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use exception control to treat what is normally an error as no error or to treat a warning as an error. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node. status is TRUE (X) if an error occurred before this VI or function ran or FALSE (checkmark) to indicate a warning or that no error occurred before this VI or function ran. The default is FALSE. code is the error or warning code. The default is 0. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code. source specifies the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning. The default is an empty string.
	unit labels returns the unit label for each member of desired units. crosstalk unit label returns a string that corresponds to the selected crosstalk units. phase unit label returns the unit label for the selected phase units. detected tone stimulus amplitude unit label returns a string that corresponds to the selected amplitude units for the amplitude of the fundamental tone as measured on the stimulus channel. detected tone response amplitude unit label returns a string that corresponds to the selected amplitude units for the amplitude of the fundamental tone as measured on the response channel.
	complex spectrum stimulus X is the complex form of the computed spectrum for the stimulus channel. complex spectrum stimulus is the complex form of the spectrum for the stimulus channel. f0 returns the start frequency, in hertz, of the spectrum. df returns the frequency resolution, in hertz, of the spectrum. complex spectrum returns the complex form of the computed spectrum. spectrum info stimulus contains information about the computed spectrum for the stimulus channel.
	complex spectrum idle-channel response Y is the complex form of the computed spectrum for the response channel. complex spectrum response is the complex form of the spectrum for the response channel. f0 returns the start frequency, in hertz, of the spectrum. df returns the frequency resolution, in hertz, of the spectrum. complex spectrum returns the complex form of the computed spectrum. spectrum info response contains information about the computed spectrum for the response channel.
	crosstalk returns the ratio of the response amplitude to the stimulus amplitude at the detected fundamental frequency. Separation measurements are equivalent to crosstalk measurements.
	phase lag returns the phase delay of the tone at the detected fundamental frequency between the stimulus and response channels.
	error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function produces. Right-click the error out front panel indicator and select Explain Error from the shortcut menu for more information about the error. status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred. code is the error or warning code. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code. source describes the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning.
