摘要： Calibrating jitter in a communication channel between test equipment and a connection for a device under test (DUT) includes sampling test data in the communication channel at about a point of the connection to produce sampled data, where the test data travels through the communication channel at a first rate, and where the test data is sampled at a second rate that is less than the first rate, determining a first amount of jitter in the sampled data relative to the test data, and determining a second amount of jitter at about the point of connection based on the first amount of jitter.

摘要： A calibration device is provided for use with automatic test equipment (ATE). The calibration device includes circuitry having a fanout circuit. The compare-side fanout circuit has an input connected to a first channel of the ATE and outputs connected to N (N>1) channels of the ATE, where the N channels do not include the first channel. The ATE propagates an edge on the first channel, and the fanout circuit transmits the edge to the N channels. Optionally, a calibration device for use with automatic test equipment includes a drive-side circuit. The drive-side circuit includes circuitry having multiple inputs connected to N (N>1) channels of the ATE and an output connected to a second channel of the ATE that is not one of the N channels. The ATE propagates an edge on each of the N-channels and the circuitry propagates each edge to the second channel of the ATE.

摘要： A trackpad has a cover abutting a housing. The cover includes a body that is transparent to infrared light and visible light. A first ink, deposited in a first area on a surface of the cover body, is transmissive to the infrared light and substantially opaque to visible light. A second ink is deposited in at least one second area on the surface of the cover body and is transmissive to visible light. A first emitter, within the housing, produces infrared light that is transmitted through the cover. A second emitter, within the housing, produces visible light that is transmitted through each second area of the cover. An optical sensor is provided within the housing for receiving infrared light that is reflected by an external object back through the cover.

摘要： The invention relates to methods for synchronising a device to a signal containing a train of pulses representing a programmable number of repetitions of a predetermined code. Pulse position and code phase are searched for. In a first aspect, a programmable number of samples is taken per pulse frame in function of the available number of repetitions of said predetermined code. In a second aspect, the method comprises a signal detection stage from which, after performing a confirmation stage, information can be kept for a subsequent stage. In a third aspect, only a limited number of rotated versions of the predetermined code are checked, using a presumed code phase which is kept from a preceding stage.
