Measuring instrument
In the physical sciences, quality assurance, and engineering, measurement is the activity of obtaining and comparing physical quantities of real-world objects and events. Established standard objects and events are used as units, and the process of measurement gives a number relating the item...
s commonly designated Reflectometer are:
- Vector Network Analyser (VNA)Network analyzer (electrical)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...
- Spectrophotometer: in optics, an instrument for measuring the reflectivity or reflectance of reflecting surfaces
- Optical time domain reflectometerOptical time domain reflectometerAn optical time-domain reflectometer is an optoelectronic instrument used to characterize an optical fiber. An OTDR injects a series of optical pulses into the fiber under test. It also extracts, from the same end of the fiber, light that is scattered or reflected back from points along the fiber...
- Reflectometer (electronics): In electronics, a directional coupler containing matched calibrated detectors in both arms of the auxiliary line, or a pair of single-detector couplers oriented so as to measure the electrical power flowing in both directions in the main line
- Time-domain reflectometerTime-domain reflectometerA time-domain reflectometer is an electronic instrument used to characterize and locate faults in metallic cables . It can also be used to locate discontinuities in a connector, printed circuit board, or any other electrical path...
