Description
Overview
GAOTek Digital Storage Oscilloscope integrates a digital oscilloscope, a logic analyzer, a FFT spectrum analyzer, an electronic counter and a clock Jitter analyzer into one device. This device offers a remarkable bandwidth combined with sufficient storage which allows to make accurate measurements. The module efficiently solves complicated trigger problems by providing a comprehensive set of triggers such as rising or falling edge, pulse width, delayed and count. It allows to effectively measure and record signals for playback and evaluation. This Oscilloscope is cost effective since it is PC based that consists of a specialized signal acquisition board which is an external USB and it is is commonly used for the maintenance of electronic equipment and laboratory work. It is also suitable for field use in sciences, medicine, engineering and telecommunications.
