I got a new Rigol DS1054Z two month ago. I general, I am quite happy with it, and at least regarding the basic stuff, I can handle it confidently (have not checked much of the fancy stuff like protocol analysis or waveform tests). However, somehow I regularly manage to get it into a state in which it behaves pretty funky:
- sluggish screen updates kind of like a slide show
- weird behavior of vertical units: change vertical division by one step, and the curve is suddenly nowhere to be found.
I feel this happens just by using basic stuff like v/h offset/division, trigger mode. Especially nothing fancy or expensive like math.
Yesterday, when I used the pulse trigger for the first time to look for issues in a PWM signal, the trigger point ended up outside (before) the recorded range in single shot mode. I suspect this might have to do with the sluggish reactions of the screen ...
All of this is regularly resolved by pressing the AUTO button. Then I can adjust everything as I want and it is fine again.
Also I can observer that at slow timescales, like 1 second, the screen is only updated half of the time, on the right halve. when the signal reaches the right edge of the screen, it stops updating for 6 seconds until the signal is at the center, then it updates the left halve at once.
Are these features I don't understand, or are these quite obvious bugs in plain sight? I am on the 04.04.SP1 firmware that was shipped with the scope, and it is unlocked.
