# Trace Representation Panel

- 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 applied to 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.
