EE· PRO is a ultra-fast, easy-to-use, plug-in card for the HP 48 GX/SX, and an invaluable aid in solving a variety of practical problems encountered by both students and professionals in electrical engineering. Designed for speed, accuracy, and ease of use, this "plug and play" software gives the user the ability to find quick solutions to sets of complex problems. It is akin to carrying a full set of "solutions in your pocket".

Product Description

Main Features

Over 1000 advanced EE analysis routines, equations, and
reference tables contained in a 128k card.

Has all the functionality of the HP 16C calculator including
50 functions in binary arithmetic, register operations, and logic minimization (Karanaugh
Map) in a sum of products form.

A powerful user interface engine allows algebraic entry in
many analytical topics. Gives results symbolically.

Easy-to-use, menu-based interface.

Context-sensitive help text for every screen.

Integrated access to the HP 48 stack for calculations.

Comprehensive documentation for quick reference.

The user interface browser presents three broad categories
to the user: analysis, equations, and reference. The analysis browser presents 17 topics,
the equation browser presents 18 categories, and the reference browser presents 10
categories. Analysis Browser

Top Level Browser

Equation sets in a given sub-topic can be solved as a
whole, or as a selected set of equations. The variables in the equation set have
descriptions in addition to names, and often an equation set will have a picture
associated with it. The help line is dynamic in content and changes as you proceed in
solving the selected problem.

A specific equation can be selected to plot, and multiple
plot functions can be used to do graphical analysis when one of the variables has been
changed incrementally. (The multi-plot screen display example is shown here.)

EE· PRO is a comprehensive software which covers
the undergraduate curriculum for electrical engineers in most universities.

Analysis

The analysis routines in the EE· PRO are
indispensable tools for performing quick calculations. Analysis screens display a list of
fields for entering and displaying data. The main part input screen contains input fields
for data entry comparisons and result for displaying computed results. The help text at
the bottom of the screen describes the action required for the highlighted field or type
of result displayed Unit management is not allowed in this section.
