The HANMATEK DOS1102 (110 MHz, 1 GS/s) oscilloscope is a beginner-friendly oscilloscope for ripple, PWM, and power testing. AC coupling removes DC offset to show small signal changes, while DC coupling shows the full waveform.
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.
