A simple tweak to the usual setup is all that is needed to enhance a spectroscopy technique that uses waves in the terahertz region to probe samples, RIKEN physicists have discovered 1,2.. Developing ...

We make a very simplistic MultiSim SPICE model of the transmission line being driven by a 50-Ω source impedance of the left in the Figure 1 with a load resistance whose value we are going to set to ...

Rotating machinery fault diagnosis is of great importance to guarantee safe and optimal operations of industrial processes. Heavy noise and dynamic behaviors usually make accurate mechanical fault ...

Fault diagnosis aims to accurately and timely identify and locate equipment faults to ensure the safe and steady functioning of systems. The rise of multimodal data has led to widespread interest in ...

The basic concepts underpinning time-domain reflectometry. Difference between frequency- and time-domain analysis. Some applications of TDR measurements. Time-domain reflectometry (TDR) is a ...

With the TDR functionality, it’s possible to “filter” the gain-frequency graph with a filter in time. Effectively, the VNA software can do a TDR transformation of the frequency measurement, remove ...

[Gregory] is building some microwave gear and wanted to convert a 3.3 GHz signal to a 12 MHz intermediate frequency. You might think of using a mixer, but you’d need a local oscillator of nea… ...
