Eletric Oscilloscope

Eletric Oscilloscope is the device used to view the signals coming directly from devices such as sound cards, allowing the real-time display of waves. It is used as electrocardiograms, to test circuits and to troubleshoot electronic devices such as televisions. Eletric Oscilloscope has gained us high rising appreciation and demands from our customers among that of our competitors.
