Abstract

A host instrument is disclosed that is capable of supporting non-native command sets. The host instrument uses interpretation rules to translate a non-native command into one or more actions. The host instrument also uses the interpretation rules to determine the appropriate responses to be transmitted, if any. The actions and responses of the host instrument emulate those of an alternate instrument that supports the command set.

Claims

1. A method of interpreting a non-native command on a host instrument, comprising:

receiving a non-native command by the host instrument, wherein the non-native command is part of a command set supported by an alternate instrument to trigger the alternate instrument to perform one or more actions when received;

in response to receiving the non-native command by the host instrument, applying interpretation rules by the host instrument to the non-native command to determine the one or more actions that the non-native command instructs the alternate instrument to perform, wherein the interpretation rules are pre-defined scripts supported by the host instrument and downloaded to the host instrument without altering a firmware of the host instrument; and

performing by the host instrument the one or more actions that the alternate instrument performs upon receiving the non-native command.

2. The method of claim 1 wherein a remote interface couples a computer to the host instrument, and the host instrument receives the non-native command from the computer through the remote interface.

3. The method of claim 1, further comprising transmitting by the host instrument one or more responses, wherein the one or more responses are transmitted by the alternate instrument when the alternate instrument is sent the non-native command.

4. The method of claim 3 wherein a remote interface couples a computer to the host instrument, and the host instrument responds to the non-native command from the computer through the remote interface.

5. The method of claim 1 wherein the interpretation rules comprise logical elements and standard functions.

6. The method of claim 1 wherein performing the one or more actions includes operating upon a device or environment.

7. A host instrument for interpreting a non-native command, comprising:

an interface for receiving the non-native command by the host instrument, wherein the non-native command is part of a command set supported by an alternate instrument to trigger the alternate instrument to perform one or more actions when received, and further wherein the interface includes a physical communication topology;

means for applying interpretation rules to the non-native command, in response to receiving the non-native command by the host instrument, to determine the one or more actions that the non-native command instructs the alternate instrument to perform, wherein the interpretation rules are pre-defined and downloaded to the host instrument without altering a firmware of the host instrument; and

a module for performing by the host instrument the one or more actions that the alternate instrument performs upon receiving the non-native command.

8. The host instrument of claim 7, further comprising transmitting one or more responses, wherein the one or more responses are transmitted by the alternate instrument when the alternate instrument receives the non-native command.

9. The host instrument of claim 7 wherein the interpretation rules comprise logical elements and standard functions.

10. The host instrument of claim 7 wherein performing the one or more actions includes operating upon a device or environment.

11. A method of applying interpretation rules to a non-native command on a host instrument, comprising:

receiving the non-native command at a host instrument, wherein the non-native command is part of a command set supported by an alternate instrument to trigger the alternate instrument to perform one or more actions upon a device or environment when received;

parsing the non-native command into a root command and a set of arguments;

applying the interpretation rules to the root command;

applying the interpretation rules to the set of arguments, if any arguments are present; and

acting upon the device or environment responsive to applying the interpretation rules to the root command and the set of arguments, wherein the host instrument responds to the non-native command by performing the one or more actions upon the device or environment that the alternate instrument performs upon receiving the non-native command.

12. The method of claim 11 wherein the interpretation rules are applied to the set of arguments sequentially in the order listed in the non-native command.

13. The method of claim 11 wherein the host instrument is coupled to a computer through a remote interface, and further wherein the host instrument receives the non-native command through the remote interface.

14. The method of claim 11, further comprising:

applying the interpretation rules to determine one or more responses that the alternate instrument transmits in response to receiving the non-native command; and

transmitting the one or more responses.

15. The method of claim 14 wherein the host instrument is coupled to a computer through a remote interface, and further wherein the host instrument transmits the one or more responses to the computer through the remote interface.

16. A host instrument capable of interpreting a non-native command, comprising:

a remote interface coupling the host instrument to a computer;

a database for storing interpretation rules for interpreting the non-native command, wherein the non-native command is part of a command set supported by an alternate instrument to trigger the alternate instrument to perform one or more actions when received; and

a processor for applying the interpretation rules to the non-native command to determine the one or more actions that the non-native command instructs the alternate instrument to perform;

performing by the host instrument the one or more actions that the alternate instrument performs upon receiving the non-native command.

17. The host instrument of claim 16 wherein the processor further applies the interpretation rules to:

determine one or more responses that the alternate instrument transmits in response to receiving the non-native command; and

transmitting the one or more responses.

18. The host instrument of claim 16, further comprising a user interface for allowing a user to directly control the host instrument.

19. A non-transitory computer-readable medium carrying instructions for a method to permit a user to debug a set of interpretation rules for a host instrument, the method comprising:

providing one or more sets of interpretation rules to be selected by a user for downloading to a host instrument;

transmitting one or more non-native commands to the host instrument, wherein the one or more non-native commands is part of a command set supported by an alternate instrument to trigger the alternate instrument to perform one or more actions when received; and

providing access to the one or more sets of interpretation rules for editing by the user, wherein the host instrument applies the downloaded and edited interpretation rules to the one or more non-native commands to determine the one or more actions that the one or more non-native commands instruct the alternate instrument to perform;

wherein the edited interpretation rules are subsequently used by the host instrument to interpret the one or more non-native commands to determine the one or more actions and performing by the host instrument the one or more actions that the alternate instrument performs upon receiving the non-native command.

20. The computer-readable medium of claim 19 wherein the one or more non-native commands are part of an application program.

21. The computer-readable medium of claim 19 wherein the one or more non-native commands are individually entered by the user.

22. The computer-readable medium of claim 19 wherein providing one or more sets of interpretation rules to be selected by a user comprises providing a point-and-click user interface.

23. The computer-readable medium of claim 19 wherein each set of interpretation rules corresponds to a different command set, and further wherein each command set corresponds to one or more alternate instruments.

24. The computer-readable medium of claim 19 wherein the computer-readable medium is a memory of a computer system.
