Modern vehicles rely on complex electronics that OBD scanners can’t fully reveal. Automotive oscilloscopes like the Hanmatek DOS1104 capture ignition, sensor, and CAN bus waveforms in real-time. With 4 channels, 110 MHz bandwidth, and 1 GSa/s sampling, technicians can pinpoint faults efficiently.
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.
