Tone Measurements (Single Tone Measurements) (G Dataflow)

Source of the signal and spectrum to export.

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

Center frequency to use in the frequency-domain search for the single tone.

Default: -1

Frequency width, as a percentage of the sampling rate, for the frequency-domain search for the single tone frequency.

Default: 5

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

The peak amplitude of the detected tone.

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

The frequency, in hertz, of the detected tone.

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

Phase, in degrees, of the detected tone.

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