Amplifier

An amplifier is a type of electronic test equipment that amplifies radiofrequency (RF) and microwave signals using the antenna. Amplifiers are ideal when used for electromagnetic interference (EMI) testing, cell phones, microwaves, radio communications, and other such applications. Engineers involved in the design, installation, maintenance, and testing of circuits can use an amplifier for laboratory applications that need moderate power output, high gain, and instantaneous bandwidth. ValueTronics has top-quality new, used, and refurbished amplifiers for sale

Arbitrary Waveform

An arbitrary waveform generator (AWG) is a type of electronic test equipment people use to generate repetitive or single-shot electrical waveforms. Single-shot waveforms require a triggering source, either internal or external, while repetitive waveforms do not. Inject the signal the waveform generator creates into a device for analysis during testing, finding problems with the device, or confirming proper operation. AWGs have maximum frequencies of around a few gigahertzes due to the digital signal processing techniques they use to generate waveforms. Unlike function generators, arbitrary waveform signal generators create any defined waveshape as their signal output. Some AWGs, such as a sine wave generator, also work as conventional function generators.

Analyzers take measurements in ohms – the ratio of voltage to current. From hospitals to auto garages, people use impedance analyzers for industrial analysis, technology production, and research. Test radio transmissions, find faults, measure cables, and use high-resolution analyzers for numerous biomedical, energy, and high technology fields.

Impedance

Impedance meters measure and log information regarding electrical equipment voltage and current. Impedance is the opposition to the flow of electrical current between a source and load. In an alternating current (AC) system, impedance testing measures resistance and reactance. In a direct current (DC) unit, you only need to document resistance. Measuring the electrical impedance of a load allows you to collect information about a piece of electrical equipment and measure its performance. Audio impedance meters enable you to troubleshoot a variety of sound system issues, running basic or complex tests, to find and repair the source of the problem. We offer used and new impedance meters from top brands.

Insulation

An insulation resistance (IR) test, commonly referred to as a Megger test, collects information such as insulation resistance. An insulation meter, or Megger tester, uses an applied direct current voltage to measure insulation resistance, creating a log of the condition of the insulation between two conductive parts. The higher the level of insulation resistance, the better the shape of the insulation. Megger testers enable you to document the performance of insulators, measuring resistance value and testing for leakages. Insulation meters confirm your circuit’s reliability, especially in final checks during new equipment installations. Megger testers are a safe and effective way to test the insulation resistance of your equipment.

LCR

An LCR meter is a piece of electronic test equipment that measures inductance (L), capacitance (C), and resistance (R) of electronic components. The LCR meter accurately measures these elements on an electronic device, usually one subjected to an alternating current (AC) voltage source. The LCR meter measures the current through and voltage across the device under test. The meter takes the ratio of these measurements to determine the magnitude of the device’s impedance. Use an LCR meter with various bridge circuits to measure inductance, capacitance, and resistance of a piece of equipment. Bridge circuits enable you to adjust variable calibrated elements for a signal to become null rather than measuring impedance.

Mixer

A waveguide mixer is electronic test equipment engineers use to achieve low conversion loss and flat frequency response. Engineers use external mixers, harmonic mixers, preselected mixers, millimeter mixers, and general-purpose waveguide mixers to ensure an electronic device exhibits a flat response (the same input and output). Mixers help a device operate more efficiently by reducing the amount of information lost over an output signal that’s not flat. Shop ValueTronics.com for used and refurbished waveguide mixers.

Meters & DAQ

What is a DAQ system? Data acquisition (DAQ) is the process of using a computer to measure electrical or physical components such as current, voltage, pressure, sound, or temperature. DAQ systems collect information via sensors, measurement hardware, and a computer with software. DAQ sensors pick up and document information such as resistance, current, or other electrical phenomena that vary over time. The information is then logged into the computer, or the data acquisition system, for accurate, safe, and simple reading. Meters are important for assessing physical and electrical components. Depending on your application, you will need to select a DAQ system that is appropriate for the type of signals you need to generate or measure.
