Abstract

A test and measurement device for testing an electronic device under test comprises a test controller, which is configured to control the test and measurement device to perform tests with the electronic device under test based on respective user provided configuration parameters, and a memory device, which is coupled to the test controller, wherein the test controller is configured to automatically store for every test in the memory device a parameter set comprising the user provided parameters.

Claims

1. A test and measurement device for testing an electronic device under test, the test and measurement device comprising:

a test controller controlling the test and measurement device to perform tests with the electronic device under test based on respective user provided configuration parameters,

a memory device coupled to the test controller,

wherein the test controller automatically stores for every test in the memory device parameter sets comprising the user provided configuration parameters,

a display device displaying representations of the stored parameter sets, and

a tabbed interface that is displayed on the display device,

wherein every tab of the tabbed interface comprises one of the representations of the stored user provided parameter sets;

said test controller further storing an image representing the parameter sets of user provided configuration parameters,

wherein said image comprising at least one of a measurement curve recorded during the test, and

a screen shot of a complete content of the display device as shown during the test.

2. The test and measurement device according to claim 1, comprising a user input device that receiving a user selection of one of the displayed representations,

wherein the test controller loads a respective set of user provided configuration parameters based on the user selection.

3. The test and measurement device according to claim 1, wherein the test controller storing measurement results of a measurement together with the respective parameter set and dynamically generating the representation of the respective parameter set based on the measurement results.

4. The test and measurement device according to claim 1, wherein when a tab is selected the test controller is configured to automatically load the respective parameter set and configure the test and measurement device according to the loaded parameter set.

5. The test and measurement device according to claim 1, wherein the tabbed interface comprises in the every tab a fully operational display of the test and measurement device.

6. The test and measurement device according to claim 1, comprising a new parameter set user input, wherein the test controller is configured to create a new parameter set after the new parameter set input is selected and store any parameter that is set by a user in a new parameter set.

7. The test and measurement device according to claim 1, wherein the test controller is configured to delete an oldest parameter set from the memory device and store a new parameter set in the memory device, when the capacity of the memory device is depleted.

8. The test and measurement device according to claim 7, comprising a marking user input configured to receive a user input regarding a respective parameter set, wherein the test controller is configured to mark the respective parameter set as permanent after receiving the user input and when deleting the oldest parameter set from the memory device skipping the parameter sets marked as permanent.

9. An operating method for operating a test and measurement device, the method comprising:

receiving user provided configuration parameters for tests with an electronic device under test,

performing the tests with the electronic device under test based on the received user provided configuration parameters,

automatically storing every test parameters set comprising the user provided configuration parameters, and an image representing the configuration parameters;

displaying representations of the stored parameter sets, and

displaying a tabbed interface,

wherein every tab of the tabbed interface comprises one of the representations of the stored test parameter sets, and

wherein said image comprising at least one of a measurement curve recoded during the test, and

a screen shot of a complete content of the display device as shown during the test.

10. The operating method according to claim 9, further comprising

receiving a user selection of one of the displayed representations, and

loading a respective set of user provided configuration parameters based on the user selection.

11. The operating method according to claim 9, comprising storing measurement results of a measurement together with the respective parameter set and dynamically generating the representation of the respective parameter set based on the measurement results.

12. The operating method according to claim 9, wherein when a tab is selected the respective parameter set is automatically loaded and the test and measurement device is configured according to the loaded parameter set.

13. The operating method according to claim 9, wherein the tabbed interface comprises in the every tab a fully operational display of the test and measurement device.

14. The operating method according to claim 9, comprising creating a new parameter set after receiving a new parameter set input and storing any parameter that is set by a user in the newly created parameter set.

15. The operating method according to claim 9, wherein an oldest parameter set is deleted from a memory device and a new parameter set is stored in the memory device, when the capacity of the memory device is depleted.

16. The operating method according to claim 15, comprising receiving a marking user input regarding a respective parameter set, wherein the respective parameter set is marked as permanent after receiving the marking user input and when deleting the oldest parameter set from the memory device the parameter sets marked as permanent are skipped.
