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.
Fuel Cell and Solar Test Equipment
Battery, fuel cell and solar test equipment consists of specialized test stations, stands or systems, monitors and component modules for performance or endurance testing.
Hardness Testers
Hardness testers measure a material's resistance to indentation. This calculation is determined by measuring the permanent depth or projected area of the indentation.
Instrument Calibration Services
Instrument calibration services test equipment and calibrate them to various standards.
ISDN Testers
ISDN testers verify the communication services provided by ISDN equipment.
Laboratory Thermometers
Laboratory thermometers are used to measure temperatures or temperature changes with a high degree of precision. Traditional liquid-in-glass design offers ease of use and low cost.
LCR Meters
LCR meters and impedance meters measures inductance (L), capacitance (C), and resistance or impedance (R).
Logic Analyzers
Logic analyzers are used to characterize and debug hardware, design and test firmware and software, and perform synthesis integration.
Noise, Vibration, and Harshness (NVH) Test Equipment
Noise, vibration, and harshness test equipment are equipment used to test and monitor noise, vibration, and harshness in mechanical and electrical systems.
Oscilloscopes
Oscilloscopes translate an electronic signal into a pattern or waveform on a screen. As it is traced across the screen, the waveform creates a signature of the signal's characteristics.
Packet Generators
Packet generators create a discrete chunk of communication in a pre-defined format.
Power Quality Analyzers and Monitors
Power quality analyzers measure and monitor electrical power parameters to avoid disturbances, track steady-state variations, and ensure the reliability of power distribution systems.
Scalar Network Analyzers
Scalar network analyzers measure the amplitude portion of scattering or S-parameters, reflection and transmission coefficients between the incident and reflection waves that describe a device’s behavior under linear conditions at the microwave frequency range.
Signal Generators
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.
Spectrum Analyzers and Signal Analyzers
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.
