Looking at the same simple signal on my two oscilloscopes: my #vitage #Hameg and my fancy 4 channel #Siglent.

The Hameg picks it up easily, the Siglent doesn’t, what’s going on?

Back in the days we learned to “throw all levers at the upper position and you’ll catch something on the scope” and there’s a degree of truth to it. Doing that on the Hameg, sets the trigger to AC and it’ll immediately capture a DC offset signal like the one shown.

For some weird reason, every digital scope I’ve ever had my hands on, defaulted to ‘DC’ trigger, which forces you to adjust the trigger level pretty much every time you want to capture a signal.

I’ve now set my scope to default at AC triggering, it’ll cover me 90% of the time, and I can always use DC triggering if I need to capture single events at specific amplitudes.

Interesting failure case, this trace literally boiled of the pcb and then fell of as flakes of copper, before and after pictures of the repair . #hameg #repair #pcb
