The scope is realized with a standard 1.6mm 2 layer PCB, without using any fancy BGA or QFN components. This post is a basic analysis of how this oscilloscope works with some consideration of its limits, and it may be interesting to better understand how a basic DSO works. ![]() As Hantek also sells similar models with higher performances, I immediately took the device apart to better understand how it works and to see if it can be pushed a bit more, especially regarding the realtime sample rate. The DSO-2090 is marketed as an 100 MSPS with 60 MHz analog bandwidth, though the full sample rate is available only when using a single channel. As part of my electronics test gears, I’ve recently got myself a cheap USB oscilloscope: a Hantek DSO-2090.
