Abstract
A method for use with automatic test equipment (ATE) includes programming the ATE to generate bursts, each of which corresponds to a signal characteristic produced by the ATE, obtaining power levels for the bursts, and determining if the power levels for the bursts correspond to expected power levels for signal characteristics corresponding to the bursts.
Claims19
A method for use with automatic test equipment (ATE), comprising:
- programming the ATE to generate bursts, each of the bursts corresponding to a signal characteristic produced by the ATE;
- obtaining power levels for the bursts;
- determining if the power levels for the bursts correspond to expected power levels for signal characteristics corresponding to the bursts;
- and
- calibrating the ATE based on a determination of whether one or more of the power levels corresponds to one or more expected power levels;
- wherein the programming, obtaining, determining, and calibrating are performed without connecting a device to be tested to the ATE.
3 more elements
A system comprising:
- automatic test equipment (ATE) that is configured to generate bursts, each of the bursts corresponding to a signal characteristic that is producible by the ATE;
- a sensor configured to obtain power levels for the bursts;
- and
- a processing device configured to determine if the power levels for the bursts correspond to expected power levels for signal characteristics corresponding to the bursts, and to calibrate the ATE based on a determination of whether one or more of the power levels corresponds to one or more expected power levels;
- wherein the power levels are obtained and the ATE is calibrated without connecting a device to be tested to the ATE.
2 more elements
A system comprising:
- signal generation circuitry configured to provide information to a device, the information corresponding to signal characteristics;
- the device configured to receive the information and to generate bursts based on the information;
- a sensor configured to obtain power levels for the bursts;
- and
- a processing device configured to determine if the power levels for the bursts correspond to expected power levels for signal characteristics corresponding to the bursts, and to calibrate the device based on a determination of whether one or more of the power levels corresponds to one or more expected power levels;
- wherein the power levels are obtained and the device is calibrated without connecting a device to be tested to the device configured to generate the bursts.
