Abstract

An apparatus and method for providing an end-user operator with the ability to assign temporary control of a set of one or more operator-specified instrument control operations to one, single-action switch on a signal measurement system front panel. The assigned instrument control operations are preferably represented by text strings in a macro text file that is developed and modified with the use of a text editor integrated into or operatively coupled with the signal measurement system.

Claims

1. A macro management system embedded in a signal measurement instrument that provides an operator of the signal measurement instrument with a capability to invoke execution of an operator-defined executable macro file comprising one or more instrument control commands through a single operator action, wherein the macro file is stored by the signal measurement instrument and each said one or more instrument control commands represents one or more instrument control operations to be performed by the signal measurement instrument.

2. The system of claim 1, wherein said single operator action is activation of a macro control key on a control panel of the signal measurement instrument.

3. The system of claim 1, wherein said single operator action is a graphical selection of a display element presented on a graphical user interface of the signal measurement instrument.

4. The system of claim 1, wherein said one or more instrument control commands comprising said macro file are descriptive, high level commands of an instrument control language.

5. The system of claim 4, wherein said instrument control language is GPIB.

6. The system of claim 1, wherein said macro management system comprises:

a macro file generation unit configured to provide the operator with a capability to develop, store and edit one or more macro text files each comprising one or more text strings, wherein said text strings include said one or more instrument control commands.

7. The system of claim 6, wherein said one or more text strings further comprise:

one or more macro control commands for controlling execution of said macro text file.

8. The system of claim 6, wherein said macro file generation unit provides a text-editing environment on a graphical user interface to facilitate said development, storing and editing of said macro text file.

9. The system of claim 1, wherein said macro management system comprises:

a macro file execution unit configured to execute said executable macro file, wherein said execution is initiated in response to receipt of a single macro execution signal generated in response to said single operator action.

10. The system of claim 9, wherein as each instrument control command is executed, said macro file execution unit generates one or more function calls that causes the signal measurement instrument to perform said one or more instrument control operations represented by the executed instrument control command.

11. The system of claim 7, wherein said one or more macro control commands comprises:

a step command that, when executed by said macro file execution unit, causes said macro file execution unit to halt execution of said executable macro file until a next macro execution signal is received.

12. The system of claim 7, wherein said one or more macro control commands comprises;

a loop command that causes said macro file execution unit to execute one or more command strings repeatedly for a specified number of iterations.

13. The system of claim 6, wherein said macro file generation unit comprises:

a text editor configured to operate with a graphical user interface to provide a text file editing environment with which the operator can develop said one or more macro text files; and

a file processor configured to process said one or more macro text files to generate said executable macro file.

14. The system of claim 13, wherein said file processor, responsive to a macro selection command, retrieves a selected macro text file from said one or more macro text files.

15. The system of claim 13, wherein said text editor utilizes the graphical user interface to provide the operator with one or more display lists of command names from which the operator can easily select a command strings for inclusion into said macro text file, wherein selection of a command name causes said selected command string to be inserted into said macro file.

16. The system of claim 15, wherein said command strings are displayed in accordance with predetermined groups.

17. The system of claim 15, wherein one or more of said commands require arguments or parameters to be specified by the operator and wherein said text editor displays on said graphical user interface one or more prompts for the operator to enter said arguments or parameters through the graphical user interface.

18. The system of claim 13, wherein said text editor includes a template data structure in which macro file templates are stored, and said text editor displays an operator selected template for viewing by the operator.

19. The system of clam 13, wherein said ale processor converts a selected macro text file to an executable macro file by removing blank lines, queries, disallowed commands and leading and trailing blank characters.

20. The system of claim 19, wherein said macro file execution unit comprises:

a command processor that processes command strings to generate formatted commands; and

a GPIB parser that generates, for each of said formatted commands, one or more function calls that causes the signal measurement system instrument to perform said one or more instrument control operations represented by the executed instrument control command.

21. The system of claim 20, wherein said macro file execution unit further comprises:

a file viewer configured to cause generation of a display of said executable macro file with a visual indication of which command string of said executable macro file is currently being executed by said execution unit.

22. An apparatus for use in a signal measurement instrument constructed and arranged to enable an operator to temporarily assign control of one or more instrument control operations to a single control panel switch of the signal measurement instrument to which the operator has direct access.

23. A method for executing an operator-defined executable macro file comprising one or more instrument control commands stored in a signal measurement system instrument, comprising the steps of:

(a) storing, in the signal measurement instrument a macro text file comprising one or more text strings of which at least one is an instrument control command;

(b) processing said macro text file to form an executable macro file; and

(c) executing said executable macro file in response to activation of a macro control key on a control panel of the signal measurement instrument.

24. The method of claim 23, wherein said storing step (a) comprises the steps of:

(1) providing a text editor to provide a text file editing environment on a graphical user interface of the signal measurement instrument; and

(2) receiving operator inputs via the graphical user interface to develop or modify the macro text file.

25. The method of claim 23, wherein said step (b) comprises the steps of:

(1) removing bank lines from said macro text file;

(2) removing disallowed commands from said macro text file; and

(3) removing leading and trailing bank characters from said macro text file.

26. The method of claim 23, wherein said macro text file is one of a plurality of macro text files, and wherein said step (a) further comprises the step of:

retrieving a selected macro text file from said plurality of macro text files stored in memory in response to a macro selection, command.

27. The method of claim 24, wherein said text editor utilizes said graphical user interface to provide the operator with a display list of command names from which the operator can select a command string for inclusion into said macro text file, wherein selection of a command name causes said selected command string to be inserted into said macro file.

28. The method of claim 26, wherein said text strings further comprise one or more macro control commands for controlling execution of said macro file, and wherein said stop (c) comprises the steps of:

(1) executing said instrument control commands in accordance with said macro control commands to generate formatted commands; and

(2) converting said formatted commands to signal measurement instrument function calls.

29. The method of claim 28, wherein said step (c) further comprises the step of:

(3) generating of a display of said executable macro file with a visual indication of which text string of said executable macro file is currently being executed by execution unit.
