I don’t mean to derail the thread into a generic feedback-thread or such, and if you have some other mean to do this, feel free to redirect me.
Got my Arc a couple of hours ago, and yes, it worked perfectly for my use case. I was a little worried that it wouldn’t be able to pick up the small CPU wakeups we do when the device is in deep sleep steady state, but no problem there. While I’ve previously used an oscilloscope over a shunt resistor to do this, with the arc it I get a larger dynamic range, very long sample duration, and a great UI (though rough around the edges, but already very much an improvement to me) to explore the trace. Safe to say, I’m very happy already and excited to use it. (if this sounds like a fake grass-root review to anyone or so, feel free to PM me and I’ll prove otherwise, just a happy customer. In fact, I’d probably take the opportunity to talk a little about what we are selling ).
Oh, one thing I just remembered - it would be really great to be able to leave annotations in a saved project. Both like a note that accompanies the file itself, but also being able to put like bookmark-markers in the trace. That way, you could eg describe the test setup in the note, then add markers like “began TLS to backend” at 1.2s, “failed ABC” at 2.5s, etc. Makes it so much easier to convey what you are seeing when you send a saved trace to someone else.
