An impedance analyzer is a type of electronic test equipment used to measure complex electrical impedance as a function of test frequency. Impedance is an important parameter used to characterize electronic components, electronic circuits, and the materials used to make components. Impedance analysis can also be used to characterize materials ...
Microwave power meter: Measures power at microwave frequencies Multimeter: General purpose instrument measures voltage, current and resistance (and sometimes other quantities as well) Network analyzer: Measures network parameters Ohmmeter: Measures the resistance of a component Oscilloscope
Measures the contact resistance of a power switching devices. Circuit breaker analyzer: Measures the parameters of a circuit breaker. Grounding resistance tester: Measures the parameters of a soil for grounding application. Transformer oil tester: Measures the parameters of an oil in a power transformer. Circuit breaker / switchgear tester
Four-point measurement of resistance between voltage sense connections 2 and 3. Current is supplied via force connections 1 and 4. In electrical engineering, four-terminal sensing (4T sensing), 4-wire sensing, or 4-point probes method is an electrical impedance measuring technique that uses separate pairs of current-carrying and voltage-sensing electrodes to make more accurate measurements ...
A line impedance stabilization network (LISN) [1] is a device used in conducted and radiated radio-frequency emission and susceptibility tests, as specified in various electromagnetic compatibility (EMC)/EMI test standards (e.g., by CISPR, International Electrotechnical Commission, CENELEC, U.S. Federal Communications Commission, MIL-STD, DO-160 Sections 20-21-22).
LCR meter - inductance (L), capacitance (C) and resistance (R) meter (measure LCR values) The following are used for stimulus of the circuit under test: Power supplies; Signal generator; Digital pattern generator; Pulse generator; Voltcraft M-3850 portable multimeter. The following analyze the response of the circuit under test:
