10MHz Pocket Oscilloscope - DSO082

             
            






10MHz Pocket Oscilloscope - DSO082
DSO082 is specified as 10MHz analog bandwidth but its actual -3db bandwidth is closed to 15MHz by real measurement and design.
Up to 50Msps real-time sampling rate and 10mV/Div sensitivity enable the unit to carry out plenty of daily measurements for a regular electronic engineer or DIYer. Thanks to ample tactile controls and rotary encoder operations of DSO082 are straightforward and easy--there is no annoying menu navigation which is usually found with other portable oscilloscopes.

Features also packed within the gadget include 1024-point FFT, USB connection, capture save/recall, adjustable memory size, rugged enclosure, and more. Firmware is field upgradable through a simple USB cable.

10X/1X switchable BNC probe and universal power adapter are included.

Digital Oscilloscope

An Oscilloscope is electronic signal test&measurement.
Oscilloscopes are normally used for observe electrical or electronic signal.
Many types of oscilloscope depend on the application (sciences, medicine, engineering, and telecommunications industry)
Original Oscilloscope is Analog Technology.
Now Oscilloscopes are Digital Storage Technology.
