The value of a quantity being plotted depends upon its mathematical function, which you select from the Function list in the Report dialog box. The available, valid functions depend on the type of quantity (real or complex) that is being plotted. The function is applied to the quantity which is implicitly defined by all the swept and current variables.
These functions can also be applied to previously specified Quantities and Functions as Range Functions when using the Set Range Function dialog.
Some of these functions can operate along an entire curve. These are: deriv, min, max, integ, avg, rms, pk2pk, cang_deg and cang_rad. These functions have syntax as follows:
•
deriv(quantity) implicitly implies derivative over the primary sweep•
deriv(quantity, SweepVariable) explicitly means derivative over the sweep variable specified in the second argument (such as "Freq").You can select from the following functions in the Function list:
abs Absolute value
acos Arc cosine
acosh Hyperbolic arc cosine
ang_deg Angle (phase) of a complex number, cut at +/-180 ang_rad Angle in radians
asin Arc sine
asinh Hyperbolic arc sine
atan Arc tangent
atanh Hyperbolic arc tangent
avg Average of first parameter over the second parameter avgabs Absolute value of average.
