Oscilloscopes are laboratory instruments used to measure voltage against time and draw an instant graph of the voltage. They're used for a multitude of applications, most commonly to test new electrical equipment. They're one of the many instruments which need to be calibrated. They can display both alternating current AC and pulsating direct current DC wave forms from as low as 1Hz to several MHz. High-quality oscilloscopes can also display signal frequencies up to several hundred GHz.
The display of an oscilloscope is segmented into horizontal divisions and vertical divisions. The time is displayed along the horizontal section, and it displays the voltage on the vertical section.
There are many types of oscilloscope, some of which are detailed below:
As well as our extensive range of oscilloscopes, we offer a wide choice of accessories, including spectrum analysers, signal amplifiers, current probes and clamps – available from industry-leading brands such as Fluke, Keysight and ISO-TECH.
