33.20.7 Plot/Modify Input Signal Dialog Box

The Plot/Modify Input Signal dialog box allows you to customize the input signal data set. It is opened from the Fourier Transform dialog box. See Section  29.11.4 for details about the items below.

Controls

Options   allows you to process some or all of the input signal data.

Clip to Range   allows you to analyze a portion of the input signal by specifying data range.

Subtract Mean Value   reduces y axis quantities by the mean value of the relevant signal property.

Signal Statistics   displays signal information.

Min   displays the minimum value for the input signal.

Max   displays the maximum value for the input signal.

Mean   displays the average value for the input signal.

Variance   displays the variance for the input signal.

X Axis Range   allows for a portion of the input signal to be analyzed when the Process the whole data option is turned off.

Min   specifies a minimum value for the $x$ axis.

Max   specifies a maximum value for the $x$ axis.

Set Defaults   resets the $x$ axis minimum and maximum values to their original value and turns on the Process the whole data option.

Signal Plot Title   lets you create a new title or edit the original title for the input signal plot. By default, the Signal Plot Title corresponds with the title originally applied to the input signal plot.

Y Axis Label   allows you to create a new $y$ axis label or edit the original $y$ axis label. By default, the Y-axis Label corresponds with the $y$ axis label originally applied to the input signal plot.

X Axis Label   allows you to create a new $x$ axis label or edit the original $x$ axis label. By default, the X-axis Label corresponds with the $x$ axis label originally applied to the input signal plot.

Window   lets you specify a windowing technique to remove discontinuities in the FFT calculation.

None   applies no windowing technique. This is the default setting.

Hamming   applies the Hamming technique.

Hanning   applies the Hanning technique.

Barlett   applies the Barlett technique.

Blackman   applies the Blackman technique.

Apply/Plot   applies any changes you have made in the dialog box and displays the input signal data in a graphics window.

Axes...   opens the Axes dialog box, which allows you to customize the plot axes.

Write...   opens the Select File dialog box (see Section  2.1.6), in which you can save the signals to a file.
