Oscilloscopes and frequency generators are used in maintenance of electrical equipment. Oscilloscopes can analyse the shape of the electrical signal and show distortion and other inhibiting factors. Frequency generators can be used as a reference point for oscilloscopes in troubleshooting, testing and repairs. A frequency counter is a device that measures the number of events on a set time scale and can be used in conjunction with an oscilloscope and frequency generator. We offer brands such as Kenwood, Thurlby Thandar, Chauvin Arnoux and Fluke.
