Used DSO082 oscilloscope. Good working condition. Tested
DSO082 is specified as 10MHz analog bandwidth but its actual -3db bandwidth is closed to 15MHz by real measurement and design (see the sharp edge of 1MHz square signal). Up to 50Msps real-time sampling rate and 10mV/Div sensitivity enable the unit to carry out lots of daily measurements for a regular electronic engineer or DIYer. Thanks to complete button arrangement and rotary encoder operations of DSO082 are straightforward and easy, no annoying menu navigating which is usually found at 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. Its firmware is field upgradable through merely an USB cable. Besides, it is the most affordable among oscilloscopes of similar performance. Includes probe and power supply.
