## 3.2. Trace representation Panel

This panel allows the user to configure the representation of the results and the application of formulas over the original results to customize the results to be visualized.

- Domain: this list allows the user to select a parameter to visualize the results (applying a function to such parameter). For each value of this parameter one result value will be visualized.

- “Parameters”:  this button shows a window that allows the user to configure the options for the domain of the representation. This window is specific for the result type selected and includes parameters such as “step”, “frequency”, “cut” (for far field), “point”, “observation” (for near field) and “Angular Average” for results with domain in degrees and trace type as table, plot or diagram.

- Trace: this option shows the value that, as a function of the original results, will be represented as a result. This option allows the user to customize the representation results with the operation option and the selected original results.

Operation: this list allows the user to select an operation to be appliedto the trace results. The list contains all the operations supported. The operations are:

• <none>: apply the result type directly.
•  abs: returns the absolute value of the value.
• acos: returns the arc cosine value in degrees.
• acosr: returns the arc cosine value in radians.
• ampl10: returns the amplitude in dB of a squared magnitude value.
• ampl20:returns the amplitude in dB of a lineal magnitude value.
• asin: returns the arc sine value in degrees.
• asinr: returns the arc sine value in radians.
• atan: returns the arc tangent value in degrees.
• atanr: returns the arc tangent value in radians.
• ceil: rounds value to the higher integer.
• complex: returns a new complex number with the first parameter as real part and second parameter as imaginary part.
• cos: returns the cosine value of the value introduced in degrees.
• cosr: returns the cosine value of the value introduced in radians.
• dB10: returns the amplitude in dB of a squared magnitude value.
• dBNormalized10: returns the normalized amplitude in dB of a squared magnitude value.
• dB20: returns the amplitude in dB of a lineal magnitude value.
• dBNormalized20: returns the normalized amplitude in dB of a lineal magnitude value.
• deg: returns the value in degrees from a value in radians.
• exp: returns the power of ‘e’ raised to the specified the value.
• floor: truncates to the lower integer value.
• imag: returns the imaginary part of a complex value
• ln: returns the natural logarithm of the value
• log: returns the logarithm in base of the first parameter form the second parameter.
• log10: returns the logarithm in base 10 of the value.
• max: returns the maximum value of the parameters.
• min: returns the minimum value of the parameters.
• mod: returns the module of a complex value.
• nat10: returns the natural value of a squared magnitude. Returns a complex value if the input is complex and the module of the natural complex if the input is real.
• nat20: returns the natural value of a lineal magnitude. Returns a complex value if the input is complex and the module of the natural complex if the input is real.
• phase: returns the phase value from a complex value in natural units.
• pow: returns the power of the first argument raised to second argument.
• rad: returns the value in radians from a value in degrees.
• random: returns a value between 0.0 and 1.0.
• rcs: returns the Radar Cross Section value from the value.
• real: returns the real part of a complex value.
• round: returns the nearest integer value of the input value.
• sin: returns the sine of the value introduced in degrees.
• sinr: returns the sine of the value introduced in radians.
• sqrt: returns the square root of the value.
• tan: returns the tangent of the value introduced in degrees.
• tanr: returns the tangent of the value introduced in radians.

- Operation "Apply" button: this button allows the user to apply the selected operation to the represented trace. There are two possibilities to apply the operations:

• If the user selects some text in the trace text before clicking on this button, the operation will be applied over the selected text.
• If the user doesn´t select some text, the operation will be applied over the Result Type option and will be written at the cursor position of the trace text.

- Constant: this list allows the user to select a constant to be added to the trace formula. The list contains all the constants defined. The constants are:

• E: adds the value of 'e' number.
• PI: adds the value of 'PI'.
• J: adds the value of the (0,1) complex number.
• SubJ: adds the value of the (0,-1) complex number.

- Constant "Apply" button: this button allows the user to apply the selected constant to the trace formula. The constant will be applied at the cursor position of the trace text.
