What Scope Bandwidth Actually Captures a CAN Bus Glitch: 50 MHz vs 100 MHz Field Comparison
I spent a Wednesday afternoon in a tractor prototyping bay watching two scopes display the same CAN‑H line. The 50 MHz oscilloscope produced a clean, textbook differential pair — the kind you would sign off on. The 100 MHz oscilloscope sitting next to it painted a different picture entirely: a 14‑nanosecond runt pulse appearing once every eighty‑seven frames. That CAN bus glitch was […]
