Abstract

A method and apparatus for saving the operational settings of an instrument. The method comprises the steps of: initiating the saving operation, initializing, by each software object, of any software object below it, initializing the internal variables belonging to the software objects, and saving the results to a file. The file is modular, is human readable text and is a computer program. The internal variable is designated in the file by a hierarchical path and is designated in the file by a hierarchical address. The computer program in an industry standard programming language such as Visual Basic Script.

Claims

1. A method for saving and restoring an operational settings of a test instrument run by software, comprising the steps of:

initiating a saving operation for saving a set of values reflecting settings of, and adjustments to, the test instrument made by a user;

determining each of the internal variables belonging to each of a plurality of hierarchical software objects employed in the operation of the test instrument;

saving the determined results to a file in a hierarchical structure corresponding to the hierarchical structure of the software objects;

recalling the file on a test instrument different from the test instrument from which the internal variables were stored; and

setting the operational settings of the different test instrument in accordance with the recalled internal variables.

2. The method of claim 1 wherein the file is modular so that only a portion of the stored internal variables need be restored at any time.

3. The method of claim 1 wherein the internal variables are designated in the file by a hierarchical path.

4. The method of claim 1 wherein the internal variables may be modified by a change in any of the controls of the test instrument.

5. The method of claim 1 wherein the internal variables are modified to conform to any requirements of the different test instrument.

6. The method of claim 1 wherein the file constitutes a computer program.

7. The method of claim 6 wherein the computer program is an industry standard programming language.

8. The method of claim 7 wherein the industry standard programming language is Visual Basic Script.

9. An apparatus for saving and restoring operational settings of a test instrument run by software, comprising:

means for initiating a saving operation for saving a set of values reflecting settings of, and adjustments to, the test instrument made by a user;

means for determining each of the internal variables belonging to each of a plurality of hierarchical software objects employed in the operation of the test instrument;

means for saving the determined results to a file in a hierarchical structure corresponding to the hierarchical structure of the software objects;

recalling the file on a test instrument different from the test instrument from which the internal variables were stored; and

means for setting the operational settings of the different test instrument in accordance with the recalled internal variables.

10. The apparatus of claim 9 wherein the file is modular so that only a portion of the stored internal variables need be restored at any time.

11. The apparatus of claim 9 wherein the internal variables are designated in the file by a hierarchical path.

12. The apparatus of claim 9 wherein the internal variables may be modified by a change in any of the controls of the test instrument.

13. The apparatus of claim 9 wherein the internal variables are modified to conform to any requirements of the different test instrument.

14. The apparatus of claim 9 wherein the file constitutes a computer program.

15. The apparatus of claim 14 wherein the computer program is an industry standard programming language.

16. The apparatus of claim 15 wherein the industry standard programming language is Visual Basic Script.

17. A method for saving and restoring an operational settings of a test instrument run by software, comprising the steps of:

initiating a saving operation for saving a set of values reflecting settings of, and adjustments to, the test instrument made by a user;

determining each of the internal variables belonging to each of a plurality of hierarchical software objects employed in the operation of the test instrument;

saving the determined results to a file in a hierarchical structure corresponding to the hierarchical structure of the software objects;

recalling the file on a test instrument different from the test instrument from which the internal variables were stored; and

modifying the internal variables as determined by the different test instrument;

setting the operational settings of the different test instrument in accordance with the recalled, modified internal variables.
