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

Analyzers are key tools to test electronic equipment in the engineering, medical, automotive, and technological industries. Use analyzers for monitoring the performances of many different types of electronic devices. You may need analyzers for the measurement of components such as audio spectrums, voltages and currents, signals, and frequencies. Analyzers give an accurate reading of how a piece of equipment functions during development and production. They are also a helpful diagnostic for troubleshooting purposes. We sell used and new analyzers from top brands such as Instek, Agilent, BK Precision, Advantest, AEA Technology, and many others. The long list of analyzers we sell includes antenna, audio, data, impedance, logic, network, signal, spectrum analyzers, and much more.

Attenuator

Attenuators are a type of radio frequency (RF) test equipment that’s useful during RF design. When an engineer needs to reduce (attenuate) the level of an electronic signal, he or she uses an attenuator. Attenuation can protect circuit stages from receiving signal levels that are too high. RF attenuators may be fixed, switched, or variable, depending on their capabilities and applications. When you need high-performing attenuators, go to ValueTronics.com. We offer new, used, and refurbished products.

Analog

Analog oscilloscopes are the earliest and simplest type of oscilloscope. They use a vertical amplifier, horizontal amplifier, time base, power supply, and a cathode ray tube to measure an electronic instrument’s voltage against time. Analog oscilloscopes test equipment by directly applying measured signal voltage to its vertical axis. An electron beam passes on the display screen of the analog oscilloscope representing the measured signal voltage. Analog oscilloscopes have several advantages over other types, such as the tool’s intensity and focus controls you can easily adjust for a sharper display. We buy and sell new, used, and refurbished analog oscilloscopes. Request a price quote once you find the analog oscilloscope you need.

Audio

Audio analyzers, real-time (RTA) audio analyzers, and audio spectrum analyzers test and measure the audio performance of electronic devices. Use audio analyzers to test equipment such as CD players, radios, and electro-acoustical devices. With an audio spectrum analyzer, measure frequency response, level and gain, phase intermodulation distortion, signal-to-noise ratio, crosstalk, time domain display, and total harmonic distortion plus noise. Audio analyzers enable engineers and designers to monitor electronic devices for product development and production. We offer new and refurbished audio analyzers from Audio Precision, Rohde & Schwarz, Keysight, Agilent HP, Panasonic, Tektronix, and Bruel & Kjaer.

Engineers use alternating current (AC) electronic loads to test electronic applications that require linear or nonlinear AC loading. AC electronic loads have features such as constant current, resistance, voltage, and power, as well as short circuit protection capabilities. AC electronic loads test equipment and take measurements such as frequency, voltage, current, power, and resistance. AC electronic loads give engineers the ability to make measurements internally. Find high-performance used and refurbished AC electronic loads at ValueTronics.com.

AC Source

An alternating current (AC) power source is a necessary piece of equipment for laboratory testing, school electronics, general electronic field service, telecommunications, and dozens of other important applications. When it comes to generating power for electronic test equipment, you need an AC power source.
