Abstract

A method for testing electronic devices involves receiving a stimulus signal for testing a device; changing an operating temperature of at least a component of an electrical filter while maintaining settings of the electrical filter, thereby altering the stimulus signal as the stimulus signal passes through the electrical filter, to create an altered stimulus signal; and outputting the altered stimulus signal.

Claims (33)

1. A method, comprising:

receiving at an electrical filter a stimulus signal for testing a device;

changing an operating temperature of at least a component of the electrical filter while maintaining settings of the electrical filter, thereby altering the stimulus signal as the stimulus signal passes through the electrical filter, to create an altered stimulus signal; and

outputting the altered stimulus signal.

2. The method of claim 1 , wherein changing the operating temperature of at least the component of the electrical filter causes the electrical filter to perform at least one of the actions selected from the group consisting of: compensating for jitter occurring in the stimulus signal, augmenting the jitter occurring in the stimulus signal, and maintaining the jitter occurring in the stimulus signal.

3. The method of claim 2 , wherein the altered stimulus signal has a jitter corresponding to one of: less than the jitter occurring in the stimulus signal, greater than the jitter occurring in the stimulus signal, and equal to the jitter occurring in the stimulus signal.

4. The method of claim 1 , wherein the operating temperature of at least the component of the electrical filter is changed by increasing an operating temperature of the electrical filter.

5. The method of claim 1 , wherein the operating temperature of at least the component of the electrical filter is changed by decreasing an operating temperature of the electrical filter.

6. The method of claim 1 , wherein the electrical filter comprises a resistor-capacitor (RC) circuit.

7. The method of claim 6 , wherein the electrical filter includes a heating element to change the operating temperature of the RC circuit.

8. The method of claim 2 , further comprising:

determining a difference between the jitter occurring in the stimulus signal and a desired jitter; and

changing the operating temperature of at least the component of the electrical filter to compensate for the difference.

9. The method of claim 1 , wherein the stimulus signal is received from automatic test equipment.

10. The method of claim 9 , wherein the electrical filter is disposed as one of a separate unit and a portion of a printed circuit board interposed between the automatic test equipment and the device.

11. An electrical filter, comprising:

an input port receiving a stimulus signal for testing a device;

an alteration device for changing an operating temperature of at least a component of the electrical filter while maintaining settings of the electrical filter, the electrical filter altering the stimulus signal based on the operating temperature of at least the component, and the settings, to create an altered stimulus signal; and

an output port outputting the altered stimulus signal to the device.

12. The electrical filter of claim 11 , wherein the the electrical filter is configured, in response to the operating temperature of at least the component of the electrical filter to perform at least one of the actions selected from the group consisting of: compensating for jitter occurring in the stimulus signal, augmenting the jitter occurring in the stimulus signal, and maintaining the jitter occurring in the stimulus signal.

13. The electrical filter of claim 12 , wherein the altered stimulus signal has a jitter corresponding to one of: less than the jitter occurring in the stimulus signal, greater than the jitter occurring in the stimulus signal, and equal to the jitter occurring in the stimulus signal.

14. The electrical filter of claim 11 , wherein the alteration device changes the operating temperature of at least the component of the electrical filter by increasing an operating temperature of the electrical filter.

15. The electrical filter of claim 11 , wherein the alteration device changes the operating temperature of at least the component of the electrical filter by decreasing an operating temperature of the electrical filter.

16. The electrical filter of claim 11 , wherein the electrical filter comprises a resistor-capacitor (RC) circuit.

17. The electrical filter of claim 11 , wherein the alteration device comprises a heating element.

18. The electrical filter of claim 12 , further comprising:

a determination device determining a difference between the jitter occurring in the stimulus signal and a desired jitter;

wherein the alteration device changes the operating temperature of at least the component of the electrical filter to compensate for the difference.

19. The electrical filter of claim 11 , wherein the stimulus signal is received from automatic test equipment.

20. The electrical filter of claim 19 , wherein the electrical filter is disposed as one of a separate unit and a portion of a printed circuit board interposed between the automatic test equipment and the device.

21. A system, comprising:

an automatic test equipment device generating a stimulus signal; and

an electrical filter including an input port to receive the stimulus signal, an alteration device to change an operating temperature of at least a component of the electrical filter while maintaining settings of the electrical filter, the electrical filter altering the stimulus signal based on the operating temperature of at least the component, and the settings, to create an altered stimulus signal, and an output port to output the altered stimulus signal to test a device.
