Tone Measurements (Multiple Tone Measurements) (G Dataflow)

Source of the signal and spectrum to export.

This input accepts an array of enums if signal is an array of waveforms.

Default: none

Input signal.

This input accepts the following data types:

• Waveform
• Waveform in complex double-precision, floating-point numbers
• 1D array of waveforms
• 1D array of waveforms in complex double-precision, floating-point numbers

Minimum amplitude that each tone must exceed.

This input accepts an array of double-precision floating-point numbers if signal is an array of waveforms.

Default: 0.001

Maximum number of tones that this node extracts. This input must be greater than 0.

This input accepts an array of 32-bit signed integers if signal is an array of waveforms.

Default: 4

The sorting order of the tones that this node extracts.

Default: increasing frequency

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

Standard Error Behavior

Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

error in does not contain an error	error in contains an error
If no error occurred before the node runs, the node begins execution normally. If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.	If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error

Spectrum of the exported signal.

This output can return a cluster or a 1D array of clusters.

f0

Start frequency, in Hz, of the spectrum.

df

Frequency resolution, in Hz, of the spectrum.

spectrum

Computed spectrum.

Waveform of the exported signal.

This output can return the following data types:

• Waveform
• Waveform in complex double-precision, floating-point numbers
• 1D array of waveforms
• 1D array of waveforms in complex double-precision, floating-point numbers

Peak amplitude of each detected tone.

This output can return a 1D array of double-precision, floating-point numbers or a 1D array of clusters.

Frequency, in Hz, of each detected tone.

This output can return a 1D array of double-precision, floating-point numbers or a 1D array of clusters.

Phase, in degrees, of each detected tone.

This output can return a 1D array of double-precision, floating-point numbers or a 1D array of clusters.
