The Unit Utility allows you to change the default units of frequency, inductance, and capacitance. Any changes you make may be saved for re-use, and will be in place each time you run OptiMatch.

The default unit set is:

                Frequency     :     1E6      (MHz)
                Inductance     :     1E-9    (nH)
                Capacitance   :     1E-12  (pF)

This utility will let you change the current unit set, or restore the original default unit set shown above.


When you choose "(3) Unit Utility" from the Main Menu, either by pressing "3," or by using the "F3" function key, you'll enter the Unit Utility. After a brieft introductory message, the screen display will look as follows:

Unit File                 1.  Frequency      [1.0E+06]                 2.  Inductance      [1.0E-09]                 3.  Capacitance   [1.0E-12]                 Change  (1-3, R[Reset],  [<Enter>=Quit] ? _

To make a change, type either "1,2, or 3" and then enter the new unit value. When you enter a value, you must use scientific notation format.

We suggest you use standard units, like KHz (1E6), MHz (1E6), GHz (1E9), etc.

After you make changes, you'll be asked if you wish to save them. If you do save the changes, you'll see that the units listing in the System File will have changed from Normal to Modified. You can access the System File by choosing "5" from the Main Menu.


How to restore the default unit set
To restore the default unit set of MHz, nH, and pF, enter the Unit Utility, type "R" and then save the changes. Now, if you choose "(5) System File" from the Main Menu, you'll see that the units listing will be back to Normal.
