For certain high-security devices, such as card readers, ATMs, and hardware security modules, normal physical security isn’t enough – they need to wipe out their sensitive data if someone starts ...

Time Domain Reflectometry (TDR) has emerged as an invaluable tool in soil science, offering precise quantification of moisture content and the electromagnetic characterisation of soils. By ...

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 technique ...

Distributed optical fiber sensing (DOFS) is currently a mature technology that allows "transforming" a conventional fiber optic into a continuous array of individual sensors, which are distributed ...

For an RF/Microwave engineer, time domain measurements are primarily useful in identifying a device’s behavior at specific locations. And more recently, with the increasing necessity of high-speed ...

In this look at transmission line theory, we will assume an RG-58 type of coaxial cable which has a characteristic impedance of 50 Ω. Where we let C stand for the capacitance per unit length, 30 pF ...

A time domain reflectometer (TDR) measures reflections along a cable. It is similar in principle to radar. To measure those reflections, the TDR transmits an incident signal into the cable and watches ...

Time-domain reflectometry (TDR) that employs electro-optical sampling affords excellent resolution at the femtosecond level and exhibits a comprehensible impulse waveform, thereby allowing quick ...

A time domain reflectometer, or TDR, is an essential piece of test gear when working on long cables. The idea is simple: send a pulse down the cable and listen for the reflection from the far end. The ...
