If the result of the expression is complex, then its magnitude is displayed. Rules for numeric values suffixes Explicit numeric values are entered in trace expressions in the same form as in simulation analyses (by means of part properties in Capture), with the following exceptions: ■ Suffixes M and MEG are replaced with m (milli, 1E-3) and M (mega, 1E+6), respectively. ■ MIL and mil are not supported. ■ With the exception of the m and M scale suffixes, PSpice is not case sensitive; therefore, upper and lower case characters are equivalent. Example: V(5) and v(5) are equivalent in trace expressions. Unit suffixes are only used to label the axis; they never affect the numerical results. Therefore, it is always safe to leave off a unit suffix. Example: The quantities 2e-3, 2mV, and .002v all have the same numerical value. For axis labeling purposes, PSpice recognizes that the second and third forms are in volts, whereas the first is dimensionless. PSpice also knows that W=V·A, V=W/A, and A=W/V. So, if you add this trace: V(5)*ID(M13) ENVMAX(x ,d) Envelope of x. Peaks selected have a minimum number of d consecutive datapoints. NO 1. In PSpice, this function is called DDT(x). 2. In PSpice, this function is called SDT(x). Table 17-18 Analog arithmetic functions for trace expressions, Probe function Description Available in PSpice?
