Built-in Transient Signal Generators (many other generators are available in the ICAP/4 models libraries (NTSC, 3 Phase, Sawtooth, FSK, PSK, Random Noise, Repeating PWL with data from a file, etc.)
  Displays all circuit voltages, currents, power dissipation and more
  Accepts output from any SPICE program, user generated data files or directly from IsSpice
  Programmable with canned programs for Rise Time, Gain Margin and more
  Can save any displayed waveform for use as circuit stimulus
  32-bit version allows large waveforms to be displayed and analyzed
  Various scaling formats include linear, semi-log, histogram, and probability
  Multiple graphs with multiple independent scales
  Waveform Operations : RMS, Pk-Pk, Mean, Max, Min, cursors
  Add, subtract, multiply, and divide waveforms
  Math Functions : trigonometric, log, power, exp, algebraic
  Advanced Waveform Functions : Integrate, differentiate, FFT, polynomial regression, filtering, gain/phase margin prop delay, rise/fall time
  Report quality output similar to SpiceNet
The RISEFAL program instantly moves the cursors to the 10-90% points on the waveform shows the time difference in the calculator's accumulator Cross Probing from SpiceNet
