2. Time-domain reflectometer - Wikipedia

   en.wikipedia.org/wiki/Time-domain_reflectometer

   Time-domain reflectometer for cable fault detection. A time-domain reflectometer (TDR) is an electronic instrument used to determine the characteristics of electrical lines by observing reflected pulses. It can be used to characterize and locate faults in metallic cables (for example, twisted pair wire or coaxial cable), [1] and to locate ...

3. Network analyzer (electrical) - Wikipedia

   en.wikipedia.org/wiki/Network_analyzer_(electrical)

   ZVA40 vector network analyzer from Rohde & Schwarz.. A network analyzer is an instrument that measures the network parameters of electrical networks.Today, network analyzers commonly measure s–parameters because reflection and transmission of electrical networks are easy to measure at high frequencies, but there are other network parameter sets such as y-parameters, z-parameters, and h ...

4. Comparative Tracking Index - Wikipedia

   en.wikipedia.org/wiki/Comparative_Tracking_Index

   The Comparative Tracking Index (CTI) is used to measure the electrical breakdown (tracking) properties of an insulating material. Tracking is an electrical breakdown on the surface of an insulating material wherein an initial exposure to electrical arcing heat carbonizes the material. The carbonized areas are more conductive than the pristine ...

5. Trace heating - Wikipedia

   en.wikipedia.org/wiki/Trace_heating

   Electric heat tracing, heat tape or surface heating, is a system used to maintain or raise the temperature of pipes and vessels using heat tracing cables. Trace heating takes the form of an electrical heating element run in physical contact along the length of a pipe. The pipe is usually covered with thermal insulation to retain heat losses ...

6. Oscilloscope - Wikipedia

   en.wikipedia.org/wiki/Oscilloscope

   Trace storage is an extra feature available on some analog scopes; they used direct-view storage CRTs. Storage allows a trace pattern that normally would decay in a fraction of a second to remain on the screen for several minutes or longer. An electrical circuit can then be deliberately activated to store and erase the trace on the screen.

7. Curve tracer - Wikipedia

   en.wikipedia.org/wiki/Curve_tracer

   The curve tracer can display all of the interesting parameters such as the diode's forward voltage, reverse leakage current, reverse breakdown voltage, and so on. For triggerable devices such as DIACs, the forward and reverse trigger voltages will be clearly displayed. The discontinuity caused by negative resistance devices (such as tunnel ...
