An example system includes a first circuit board having first conductive traces, where a first conductive trace is for conducting an alternating current (AC) digital signal having an edge; a second circuit board having second conductive traces, where a second conductive trace is within a predefined distance of the first conductive trace to produce a contactless coupling with the first conductive trace, and where the contactless coupling enables electrical energy on the first conductive trace to manifest on the second conductive trace as a transient response that is based on the edge; and circuitry to reconstruct the edge based on the transient response from the second conductive trace.

Communicating using contactless coupling

In general, a test instrument includes a first processing system that is programmable to run one or more test programs to test a device interfaced to the test instrument, and that is programmed to control operation of the test instrument, a second processing system that is dedicated to device testing, the second processing system being programmable to run one or more test programs to test the device, and programmable logic configured to act as an interface between the test instrument and the device, the programmable logic being configurable to perform one or more tests on the device. The first processing system and the second processing system are programmable to access the device via the programmable logic.

Programmable test instrument

A process for managing interrupts, which may be performed using electronic circuitry, includes: receiving interrupts bound for a processing device, where the interrupts are received from hardware devices that are configured to communicate with the processing device; generating data containing information corresponding to the interrupts; and sending the data to the processing device.
