AC power sources provide alternating power and typically have adjustable output values for the testing of component response at various voltages, current and frequency levels.
|
|
Audio analyzers measure the noise and audio spectrum of output from an amplifier or a stereo.
|
|
Counter and timer boards are computer cards that perform digital counting and/or timing functions.
|
|
Data acquisition is the digitizing and processing of multiple sensor or signal inputs for the purpose of monitoring, analyzing and/or controlling systems and processes. Signal conditioning includes the amplification, filtering, converting, and other processes required to make sensor output suitable for rereading by computer boards.
|
|
Data acquisition I/O modules or cards have both input and output functionality. Digital or discrete I/O modules include on-off signals used in communication, user interface, or control.
|
|
Data acquisition systems and instruments collect, digitize and process multiple sensor or signal inputs for the purpose of monitoring, analyzing and/or controlling systems and processes.
|
|
Data loggers and data recorders acquire digital data from sensors and other signals. They are primarily used to store data for subsequent downloads to a host PC, but may also include real-time features such as monitors and alarms.
|
|
DC power supplies accept an input power and output the desired form of DC power. Common types of DC power supplies include linear power supplies, switching power supplies, DC-DC converters, and silicon controlled rectifier (SCR) type power supplies.
|
|
Digital multimeters (or multi-meters) are used to measure electrical quantities such as voltage, current, resistance, frequency, temperature, capacitance, and time period measurements.
|
|
Frequency counters are digital indicating meters for accurate measurement and display of square wave and pulse input signals.
|
|
Frequency meters are instruments that provide analog outputs as frequencies that vary as a function of the applied input. They display values on a dial, usually with a needle or moving pointer.
|
|
Hipot testers are electrical safety test devices that perform a variety of electrical compliance tests.
|
|
Network analyzers and protocol analyzers are test equipment used to troubleshoot and analyze network problems.
|
|
Network test equipment is used to test, probe, and analyze telecommunication, network and telephone systems.
|
|
Power supplies are devices that produce AC or DC power. This grouping includes current sources, DC power supplies, AC-DC adapters, DC-DC converters, AC power sources, and DC-AC inverters.
|
|
Programmable power supplies are digitally controlled power sources that provide accurate and adjustable levels of voltage, current, and frequency. They include a processor, voltage/current programming circuits, current shunt, and voltage/current read-back circuits.
|
|
Spectrum analyzers and signal analyzers display raw, unprocessed signal information such as voltage, power, period, wave shape, sidebands, and frequency. They can provide the user with a clear and precise window into the frequency spectrum.
