Software-based test-system architectures have become increasingly popular over the past several decades. As test applications become more complex, engineers are continuously challenged with the ...

The standard is intended to provide a uniform method of diagramming the physical interconnections of the instruments of a loop and to provide related information that ...

An expanded hardware-in-the-loop (HIL) test system promises to offer a better way to test engineering’s most complex products, from defense aircraft to autonomous cars. Introduced at this week’s ...

With the power and flexibility of today's computers, engineers and scientists are increasingly using virtual instrumentation for HIL (hardware-in-the-loop)-simulation applications. A key element of ...

The increasing use of voice-activated devices has put a spotlight on audio tests – making a case for open and closed loop testing, says Eric Hodges of Audio Precision. Classically, audio tests have ...

Switching power supplies rely on feedback control loops to ensure that the required voltage and current are maintained under varying load conditions. Design of the feedback control loop influences ...
