Introduction

The Main Menu is your starting point. By choosing "1" from the Main Menu, you enter the OptiMatch Module.

In addition to the OptiMatch Module, a File Utility allows you to create or make modifications to impedance data files. We call these .IMP files, and they are discussed in Appendix B.

Note that Users of Windows, can, if they wish, use Windows Notepad to edit and/or print .IMP files. However, if you do this, be careful, you cannot change the file format, and you cannot use an editor that adds control characters to the file. You can only use a simple ascii text file editor like NotePad.

A Unit Utility lets you choose the particular set of units you like best. The default unit set in MHz, nH, pF, and ohms, the same as our other software products. A menu option lets you restore the default set if you should change it.

The Default Utility lets you change the form of the error function and modify certain of the algorithm variables. In some situations, this can have a dramatic effect. For instance, we've been able to turn a parabolic form of VSWR vs frequency response into an equi-ripple response by making one simple algorithm change! Try that with any other optimizer! If changed, a menu option lets you easily restore the default variable set.

The System File, available as a Main Menu choice, lets you check on whether or not you currently have normal or modified units and default variables in place. It also sets a pointer corresponding to whether or not there is a system clock.

You may exit the program by simply choosing "6" from the Main Menu.

Note that all menu choices are made via "hot keys." When you are at "Choose (1-6) ? _," and type a number from 1 thru 6, you will immediately go to the page selected; it is not necessary to press <Enter>.

A built-in Element Library, (see Appendix A), allows you to create ladder networks using both lumped and distributed elements. You have the option of holding some elements fixed, and letting others vary.
