Brief Introduction to the Series of digital
storage oscilloscope
DSO4000B(C) Series oscilloscopes cover the bandwidths from 80MHz to 200MHz,
and provide the real-time up to 1GSa/s. In addition, they have 7 inch color TFT LCD as
well as WINDOWS-style interfaces and menus for easy operation.
What’s more, the plenty menu information and the easy-to-operate buttons allow you to
gain information as much as possible in measurement; the multifunctional knobs and
the powerful shortcut keys help you save a lot of time in operation; theAutoset function
lets you detect sine and square waves automatically; the Probe Check Wizard guides
you to adjust the probe compensation and set the Probe option attenuation factor. By
using the three methods the oscilloscope provides (context-sensitive, hyperlinks, and
an index), you may master all operations on the device in quite a short time so as to
greatly improve your efficiency in production and development.
