One of the most important types of test equipment used in troubleshooting, an oscilloscope ("scope") is a test equipment that provides a visible graphical display of the waveform being measured. It can be used to measure peak-to-peak voltage, frequency, time periods, wave slopes, phase angles and frequency response. Most oscilloscopes have dual-trace capabilities and storage feature. 

Alexan oscilloscopes offer a wide selection of analog and digital storage, bandwidth, and additional features such as Component Tester, advanced triggering and Fast Fourier Transform (FTT) math function.
