Oscillators are devices that are used to generate repetitive signals. They produce output signals without an input signal. There are two major types of electronic oscillators: harmonic oscillators and relaxation oscillators. Harmonic oscillators produce sine wave outputs. Relaxation oscillators produce non-sine wave outputs such as square wave, rectangular wave, and sawtooth outputs

Shaker controllers are hardware/software devices that generate one or more analog drive signals that are applied to an amplifier / shaker / test device for the purpose of creating a specified vibration environment at one or more points on a test device.

DC to AC inverters are used for converting direct current (DC) into alternating current (AC). They are also known as DC to AC converters.

Rotary position sensors include potentiometers, resolvers and a variety of magnetic and capacitive technologies. Sensors are designed for angular displacement less than one turn or for multiturn displacement.

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.

Programmable power supplies are digitally controlled power sources that provide accurate and adjustable levels of voltage, current, and frequency. They include a processor, voltage/current programming circuits, current shunt, and voltage/current read-back circuits.

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.

Three phase surge suppressors protect equipment from transient overvoltages present on AC three phase power lines. Three phase surge suppressors are not plug-in style devices.

Single phase surge suppressors protect equipment from transient overvoltages present on AC single phase power lines. They are not plug-in style devices.

AC power sources provide alternating power and typically have adjustable output values for the testing of component response at various voltage, current and frequency levels.

Plugin style surge suppressors plug into wall outlets to protect equipment from transient overvoltages.

Shakers and shock and vibration testing equipment are force generators or transducers that provide a vibration, shock or modal excitation source for testing and analysis.

Transient voltage surge suppressors protect against temporary excess voltage and/or current in an electrical circuit that has been disturbed.

VU meters measure the volume (intensity) of analog audio signals. They display signal levels in volume units (VU), a measure of average volume level.

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.
