Name Function
Intg( Calculate the integral of the selected source. You can use
integral to measure the area under a waveform or the pulse
energy.
Diff( Calculate the discrete time derivative of the selected source.
You can use differentiate to measure the instantaneous slope
of a waveform.

constant e, approximately 2.718282 as the base).
Exp( Calculate the exponent of the selected source. For example:
Exp(A) means calculating the Ath power
of e.
Sqrt( Calculate the square root of the selected source.
Sine( Calculate the sine value of the selected source.
Cosine( Calculate the cosine value of the selected source.
Tangent( Calculate the tangent value of the selected source.
4. Variable
