Hantek 6022Bl PC Digital Portable Oscilloscope

Description
An oscilloscope is a type of electronic test instrument that graphically displays varying signal voltages, usually as a two-dimensional plot of one or more signals as a function of time. Other signals (such as sound or vibration) can be converted to voltages and displayed.
Logic analyzers provide an ideal tool to verify and debug complex designs for electrical engineers. Logic analyzers are useful when multiple signals must be observed simultaneously, as well as when you need to look at a system's signals in the same way its hardware does. The biggest difference from the oscilloscope is the extra input channels it offers. 
Some digital oscilloscope relies on a PC platform for display and control of the instrument. This can be in the form of a standalone oscilloscope with an internal PC platform (PC mainboard), or an external oscilloscope which connects through USB or LAN to a separate PC or laptop.
The Hantek 6022BL is a USB-based, 2-channel oscilloscope with an analog bandwidth of 20MS/s and a 48MS/s sampling rate, and an 8-/16-channel logic analyzer with 24MHz sampling rate. The device can either be used as an oscilloscope or as a logic analyzer, but not both at the same time. I.e., it is not a mixed-signal-oscilloscope (MSO). Currently, only the 8-channel logic analyzer mode is supported.
