Analog multimeters are instruments that are used to measure electrical quantities such as voltage, current, resistance, frequency and signal power
|
|
Analog voltmeters are instruments that measure voltage or voltage drop in a circuit. They display values on a dial, usually with a needle or moving pointer.
|
|
Audio analyzers measure the noise and audio spectrum of output from an amplifier or a stereo.
|
|
Bias tees allow the insertion of DC voltages into a signal path without disrupting the existing signal in that path.
|
|
Bit error rate testers are devices or procedures that measure the bit error rate (BER) for a specific transmission.
|
|
Calibration instruments use electrical signals or physical quantities to calibrate sensors and meters. Devices that produce electrical signals can serve as precise meters for sensor calibration, or send output signals to other devices.
|
|
DC blocks are used to prevent DC energy from flowing through sensitive RF components.
|
|
Digital multimeters (or multi-meters) are used to measure electrical quantities such as voltage, current, resistance, frequency, temperature, capacitance, and time period measurements.
|
|
Digital voltmeters are instruments that measure voltage or voltage drop in a circuit. They use solid-state components and display values digitally.
|
|
Diodes are electronic components that conduct electric current in only one direction, functioning as a one-way valve. Diodes are manufactured using semiconductor materials such as silicon, germanium or selenium and are used as voltage regulators, signal rectifiers, oscillators and signal modulators / demodulators.

|
Electrical capacitance sensors detect and measure capacitance, the charge storage capacity of an electronic component.
|
|
Electrical inductance sensors measure the inductance of an electrical component or system.
|
|
Electrical power sensors are used to measure electric power.
|
|
Electrical terminators are installed at the end of a bus or transmission line to prevent signals from reflecting back. Sometimes called electrical terminators, these devices are used to prevent electrical interference.
|
|
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.
|
|
LCR meters and impedance meters measures inductance (L), capacitance (C), and resistance or impedance (R).
|
|
Network test equipment is used to test, probe, and analyze telecommunication, network and telephone systems.
|
|
Noise generators and sources are used to produce noise outputs for testing radio frequency (RF) equipment.
|
|
Noise meters are used to measure and/or monitor noise produced by RF equipment.
|
|
Noise standards are used to calibrate other noise instruments.
|
|
Power meters are used for high-accuracy measurements of power over a wide-frequency bandwidth, and from both AC and DC circuits.
|
|
RF attenuators are circuits that reduce the power level of a signal by a certain amount (gain), with little or no reflection. They reduce the output signal with respect to the input and measure the power reduction in decibels (dB).
|
|
RF couplers are circuits that sample RF transmissions by combining (coupling) signals asymmetrically. There three basic types of devices: unidirectional, bidirectional, and dual directional.
|
|
RF diplexers are three-port frequency-dependent devices that may be used as a separator or a combiner of signals. RF duplexers allow a transmitter operating on one frequency and a receiver operating on a different frequency to share a common antenna with a minimum of interaction and degradation of the different RF signals.
|
|
RF filters and microwave filters are devices that pass or reject signals by frequency. Basic types include bandpass filters, band reject filters, low pass filters, and high pass filters.
|
|
RF frequency converters are integrated component assemblies required for converting microwave signals to lower (or intermediate) or higher frequency range for further processing.
|
|
RF phase shifters are twin-ported devices that alter the phase of an output signal in response to an external signal.
|
|
RF power dividers and RF power combiners are circuits that accept input signals and deliver multiple outputs that are equal in phase and amplitude. There are two basic product categories: passive and active.
|
|
RF receivers are electronic devices that enable a particular radio signal to be separated from all others being received and converted into a format for video, voice, or data.
|
|
RF terminators are used to absorb energy and prevent RF signals from reflecting back from open-ended or unused ports.
|
|
RF test equipment generates test signals or analyzes transmitted signals from RF components or equipment.
|
|
RF upconverters and RF downconverters are used to change the frequency of an RF signal on a large scale.
|
|
RF waveguide components are circular, elliptical or rectangular metal tubes or pipes through which electromagnetic waves are propagated in microwave and RF communications. The wave passing through the medium is forced to follow the path determined by the physical structure of the guide.
|
|
Signal generators and waveform generators are used to test and align all types of transmitters and receivers, to measure frequency and to generate a signal, waveform or noise source. Signal generators can use AC energy, audio frequency (AF) and radio frequency (RF) to function.
|
|
Specialized electromagnetic sensors and instruments are proprietary electrical and electromagnetic sensors and instruments not explicitly listed elsewhere.
|
|
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.
|
|
Waveguide terminators absorb energy and prevent RF signals from reflecting back from open-ended or unused waveguide ports.
