Sparcom Spice48 PAC Calculator Card Hp 48GX/48SX # 475

The power and flexibility of Spice48 is exercised through a circuit element manager, a schematic creation manager, an analysis manager, a data file manager, a graphics manager, and an output manager. Spice48 was developed in close collaboration with experienced instructors from the University of California at Berkeley.

Circuit Manager

This is the starting point to work with Spice48. It allows you to add new circuits, delete unwanted circuits, pack circuits to free memory, or transfer circuits from a PC or Macintosh computer.

Element Manager

This application is used to add, delete, and edit elements in the current circuit. The circuit elements supported include resistor, capacitor, inductor, coupled Inductor, independent voltage and current sources, voltage controlled current or voltage source, current controlled voltage or current source, transient sources, pulse transient, piecewise linear transient, and function transient. The element manager works closely with the Node Manager which is used to add, delete, and edit nodes in the current circuit and set the reference node. A unique feature of Spice48 is that nodes can be represented by numbers or names.

Analysis Manager

The analysis manager helps analyze the circuit selected. Types of analysis allowed include operating point analysis, transfer function analysis, DC sweep analysis, AC sweep analysis, and transient sweep analysis.

Graphics Manager

This application is used to create the schematic of the current circuit by setting node coordinates, setting element coordinates and orientations, setting wire coordinates, and viewing schematics.

Data File Manager

The data file manager coordinates loading a data file, deleting a data file, or transferring a data file.

Output Manager

The output manager is used to view, plot, and save analysis data. It allows analysis and viewing of data by node, frequency, and time. Node plots, value plots, and display forms give the user a variety of choices.

Miscellaneous Information

Additional information provided in this application card includes: resistor colors, a constant library, properties of Silicon and Gallium Arsenide, standard component values for resistors, and capacitors and inductors.
