===Advanced or less commonly used equipment=== '''Meters''' * [[Solenoid voltmeter]] (''Wiggy'') * [[Clamp meter]] (current transducer) * [[Wheatstone bridge]] (Precisely measures [[electrical resistance|resistance]]) * [[Capacitance meter]] (Measures [[capacitance]]) * [[LCR meter]] (Measures [[inductance]], [[capacitance]], [[electrical resistance|resistance]] and combinations thereof) * [[EMF Meter]] (Measures Electric and Magnetic Fields) * [[Electrometer]] (Measures voltages, sometimes even tiny ones, via a [[electric charge|charge]] effect) ====Probes==== [[Image:tongtester.jpg|thumb|right|A multimeter with a built in clamp facility. Pushing the large button at the bottom opens the lower jaw of the clamp, allowing the clamp to be placed around a conductor (wire). Depending on sensor, some can measure both AC and DC current.]] * [[RF probe]] * [[Signal tracer]] ====Analyzers==== * [[Logic analyzer]] (Tests [[digital circuit]]s) * [[Spectrum analyzer]] (SA) (Measures spectral energy of signals) * [[Protocol analyzer]] (Tests functionality, performance and conformance of protocols) * [[Vector signal analyzer]] (VSA) (Like the SA but it can also perform many more useful digital demodulation functions) * [[Time-domain reflectometer]] (Tests integrity of long cables) * [[Semiconductor curve tracer]] ====Signal-generating devices==== [[Image:Leader LSG-15 signal generator.jpg|thumb|right|200px|Leader Instruments LSG-15 signal generator.]] * [[Signal generator]] usually distinguished by frequency range (e.g., audio or radio frequencies) or waveform type (e.g., sine, square, sawtooth, ramp, sweep, modulated, ...) * [[Frequency synthesiser]] * [[Function generator]] * [[Digital pattern generator]] * [[Pulse generator]] * [[Signal injector]]<ref>{{cite web |url=https://www.electroschematics.com/9455/signal-injector-circuit/ |title=Signal Injector Circuit |access-date=2018-06-03}}</ref> [[File:Cable_tester.jpg|thumb|Cable tester]]
