Electricity is a power source that is used in almost any modern gadget. Its discovery and usage allowed people to advance rapidly and create electronic equipment that greatly aids us in our everyday routine as well as in working and creating something new. Electricity runs through power lines in our homes and through our computers, phones, and other equipment we use every day. It has a set of parameters that define the behavior of electric current and should be monitored in order to keep your equipment functional and undamaged.

An example of test equipment that monitors signals and their behavior is an oscilloscope. This device provides great functionality for electric current and electric system analysis. Mega Depot offers oscilloscopes from AEMC, Elenco, and more. Find the right gadget for you!

Oscilloscopes Products List

Oscilloscopes monitor the signal behavior over a set period of time, displaying the pattern as a function against a two-directional coordinate system. They are also capable of transforming non-electric signals like vibration or sounds and displaying them as a function. They are commonly used to control and fine-tune the settings of an electric device. Modern oscillographs are usually small handheld devices with a display that shows monitored signals, and three control sections - vertical section, horizontal section, and trigger section. These devices use probes to connect to a signal.

Oscillographs can measure the amplitude, minimum, maximum, average, and mean voltages, rise and fall time, period, duty cycle, and frequency of an electric signal. These parameters are required to establish the strength and behavior of the signal. In order to begin working with the device, you should attach the electric probe to the source of the signal, adjust the controls to monitor and demonstrate the signal you desire in a fitting form and start taking measurements.
