4-channel oscilloscopes improve debugging by allowing multiple signals to be viewed at once. The HANMATEK DOS1104 offers 4 channels, 110 MHz bandwidth, and 1 GS/s sampling for faster, more accurate electronics analysis.
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.
