Time-aligning a signal

Abstract: An example method includes: obtaining sinusoidal signals comprising components of a first time-domain signal; shifting phases of the sinusoidal signals by amounts corresponding to a specified time-shift to produce phase-shifted signals, and converting the phase-shifted signals to the time domain to produce time-shifted signals. The shifting may be performed to more closely align an envelope of the first time-domain signal with an envelope of a second time-domain signal.

High performance tester interface module

Abstract: A tester interface assembly for coupling a plurality of tester electronic channels to a device-interface-board, including at least one harness assembly having a plurality of coaxial cables. Each cable includes a body having a center conductor and a shield. The shield is formed coaxially around the center conductor and separated therefrom by a layer of dielectric. Each cable further includes a distal tip formed substantially similar to the body and including formed conductivepads disposed on the distal extremities of the center conductor and the shield. The harness employs a housing formed with an internal cavity for receiving the cable distal ends in close-spaced relationship such that the distal tips form an interface engagement plane. A compliant interconnect is interposed between the harness assembly and the device-interface-board, and includes a plurality of conductors formed to engage the cable distal ends along the engagement plane.

Automatic test system with focused test hardware

Abstract: A tester interface unit comprising a test hardware module. The test hardware module may have a simple construction, relying on control and/or signal processing in one or more tester instruments to generate or analyze test signals for a device under test. The test hardware module may be disposed within the tester interface unit, providing a short and high integrity signal path length to the device under test. The tester interface unit may include a purge gas chamber and a cooling chamber, with the hardware module penetrate a separator between those chambers, sealing an opening between the purge gas chamber and the cooling chamber. A heat spreader may move heat generated on the portion of the test hardware module in the purge gas chamber to the cooling chamber.

Handler change kit for a test system

Abstract: An example system includes a receptacle to house a device under test (DUT); an antenna for exchanging signals with the DUT, where at least some of the signals are for use in performing radiated testing of the DUT; and a cap configured to mate to the receptacle to form a housing to enclose the DUT. The housing is for isolating the DUT at least one of physically or electromagnetically.

An Analysis of Requirements-Related Problems that Occurred in an organization Using a Mature Requirements Engineering Process

Abstract: Plenty has been written on the necessary elements of a requirements engineering (RE) process. When an organization experiences product development problems and is found to lack an effective RE process, it is relatively easy to find potential causes for the problems. For example, changes may not have been managed, or requirements and other artifacts may not have been traced to each other.Nevertheless, what can be said of RE process failures that occur despite an organization’s using a reasonably mature RE process? This paper will examine a set of RE-related problems that occurred in one such organization. It will also describe a solution that has been proposed to avoid such problems in the future.
