Network Analyzer (electrical)
A network analyzer is an instrument that measures the Two-port network, network parameters of electrical networks. Today, network analyzers commonly measure scattering parameters, s–parameters because Signal reflection, reflection and Transmission line, 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 Two-port network#Hybrid parameters (h-parameters), h-parameters. Network analyzers are often used to characterize two-port networks such as amplifiers and filters, but they can be used on networks with an arbitrary number of Port (circuit theory), ports. Overview Network analyzers are used mostly at high frequency, frequencies; operating frequencies can range from 1 Hz to 1.5 THz. Special types of network analyzers can also cover lower frequency ranges down to 1 Hz. These network analyzers can be used, for example, for the stability analysis of open loo ...

Logic Analyzer
A logic analyzer is an electronic instrument that captures and displays multiple logic signals from a digital system or digital circuit. A logic analyzer may convert the capture into timing diagrams, protocol decodes, state machine traces, opcodes, or may correlate opcodes with source-level software. Logic analyzers have advanced triggering capabilities, and are useful when a user needs to see the timing relationships between many signals in a digital system. Overview Presently, there are three distinct categories of logic analyzers available on the market: * Modular LAs, which consist of both a chassis or mainframe and logic analyzer modules. The mainframe/chassis contains the display, controls, control computer, and multiple slots into which the actual data-capturing hardware is installed. The modules each have a specific number of channels, and multiple modules may be combined to obtain a very high channel count. While modular logic analyzers are typically more expensive, ...

Spectrum Analyzer
A spectrum analyzer measures the magnitude of an input signal versus frequency within the full frequency range of the instrument. The primary use is to measure the power of the spectrum of known and unknown signals. The input signal that most common spectrum analyzers measure is electrical; however, spectral compositions of other signals, such as acoustic pressure waves and optical light waves, can be considered through the use of an appropriate transducer. Spectrum analyzers for other types of signals also exist, such as optical spectrum analyzers which use direct optical techniques such as a monochromator to make measurements. By analyzing the spectra of electrical signals, dominant frequency, power, distortion, harmonics, bandwidth, and other spectral components of a signal can be observed that are not easily detectable in time domain waveforms. These parameters are useful in the characterization of electronic devices, such as wireless transmitters. The display of a spec ...

Multimeter
A multimeter (also known as a multi-tester, volt-ohm-milliammeter, volt-ohmmeter or VOM, avometer or ampere-volt-ohmmeter) is a measuring instrument that can measure multiple electrical properties. A typical multimeter can measure voltage, electrical resistance, resistance, and electric current, current, in which case can be used as a voltmeter, ohmmeter, and ammeter. Some feature the measurement of additional properties such as temperature and capacitance. Analog multimeters use a microammeter with a moving pointer to display readings. Digital multimeters (DMMs) have numeric displays and are more precise than analog multimeters as a result. Meters will typically include probes that temporarily connect the instrument to the device or circuit under test, and offer some intrinsic safety features to protect the operator if the instrument is connected to high voltages that exceed its measurement capabilities. Multimeters vary in size, features, and price. They can be portable handh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
In-circuit Testing
In-circuit testing (ICT) is an example of white box testing where an electrical probe tests a populated printed circuit board (PCB), checking for shorts, opens, resistance, capacitance, and other basic quantities which will show whether the assembly was correctly fabricated. It may be performed with a "bed of nails" test fixture and specialist test equipment, or with a fixtureless in-circuit test setup. In-Circuit Test (ICT) is a widely used and cost-efficient method for testing medium- to high-volume electronic printed circuit board assemblies (PCBAs). It has maintained its popularity over the years due to its ability to diagnose component-level faults and its operational speed. Using In-Circuit Test fixtures is a very effective way of maintaining standards when carrying out tests. It can help to reduce production downtime by identifying faults early in the testing process, ensuring that defective products are removed from the production line and fixed. Fixtures for in-circu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
