The Hanmatek DOS1104 is a budget 4-channel oscilloscope with 110 MHz bandwidth, up to 1 GSa/s sampling, and a 7″ 800×480 display. It supports stable triggering, FFT, math functions, and USB export. Known for strong value and low noise, it suits R&D, embedded debugging, and power electronics.
Very good oscilloscope for the price bandwidth and sampling are as advertised altho the buffer is a bit small and is shared across all 4 channels. Lack of grounding also introduces some noise but at least thanks to that you can run it from a power bank if it supports at least 8w output so you can use it on the go.
Extraordinary performance for very low price - very impressed
Extraordinary performance for very low price - very impressed. I would like to see a clip-on stabilising base though, and would pay more for a 12/16bit version with higher FFT dynamic range.
