- NOTES ON IMPEDANCE MATCHER:
-
- 1. All files are necessary for proper operation.
-
- 2. A batch file E.BAT is used to load the proper sequence of files
-
- 3. A printed version of the help screen is useful when starting
- to use this program.
-
- 4. This is an automated version of the "back to back" Smith
- chart commonly used for impedance matching.
-
- 5. GENERAL INSTRUCTIONS:
-
- Enter the system characteristic impedance, as well as impedance
- to be matched, when prompted.
-
- The impedance will appear as a yellow circle. Locii of constant
- resistance appear in green, and locii of constant conductance
- appear in yellow.
-
- Series reactance may be added by choosing the select reactance
- function key, F5. This leaves the command mode where the
- variable is chosen, and enters the move mode with reactance
- selected as the parameter to be changed.
-
- Reactance may be added with either F3, (Coarse 20% steps) or F1,
- (Fine 2% steps). Reactance may be subtracted with either F4,
- (Coarse 20% steps) or F2, (Fine 2% steps).
-
- To return to the command mode, use F10.
-
- In the command mode, the following functions may be chosen:
-
- F5 Select reactance
-
- F6 Select susceptance
-
- F7 Select series transmission line
-
- F8 Redo the plot, retaining the original data
-
- F9 Redo the plot, prompting for new data
-
- Alt F9 Display table of Data you entered. Data will be in the
- form of X1,B2,X3,A4, ..., assuming you entered X first, B
- second, X third, and a transmission line of impedance Z0
- and length A in degrees.
-
- Home Redisplay the HELP screen
-
- Q Quit and return to DOS. (the data table will be
- displayed)
