New Rigol DS1054Z oscilloscope

<< < (896/966) > >>

marber:
About 2.5 years ago I had to shelve my electronics hobby for a while. Lack of time (new baby, new house / home improvement work) as well as lack of space until that was done (baby room...). So I put everything in storage for the time being, including my DS1074Z-S.

This week I finally got some things setup again in my new house, in a new room, and with sometimes a bit of time available. It was a bit funny to return to reading this forum and still see the exact same discussions going on between mostly the same actors... ;)

The moment I took out my DS1074Z-S out of the box to put it on my desk and carefully flipped out one of its feet, it immediately snapped. Same with the other one. The tension of the springs was apparently enough to do that. So now... I have an oscilloscope on my desk that I can no longer tilt upwards in a decent way.

I suspect the plastics may have weakened a bit over time, perhaps from the sun, as also the plastic top of the oscilloscope has yellowed slightly from bromine. It used to be near a window in my old, small apartment. The feet have always been out of reach of the sun underneath, though. :)

Anyway... I see I may not be the only one with that problem, as a bit of googling I noticed a few Rigol DS1000Z feet designs on Thingiverse etc.

Before I go that route however, has anyone ever had any luck getting such replacement parts out of Rigol? :)

So compared to the rigol, we see a peak at the beginning of each pulse, where this peak is observed i.e. after the front. On rigol is at the end of the pulse - before the front. Any explanation? Bad interpolation?

The problem cannot be interpolation when there is nothing to interpolate.  1 GS/s on the Rigol is a point every nanosecond so unless the Rigol is mangling the original sample points, there should be no problem.

Today I turned on my Rigol DS1054Z after few weeks and the language was set to Chinese, HW counter was disabled, everything was messed up. I did a reset to default, enabled counter and everything seems to work ok. Should I be concerned?

And the answer is...yes, I should be. After few more power cycles it did it again. Back it goes the piece of crap.  |O

Is using the window trigger the only way to get get a waveform across all the sample points?  For some reason, I cannot move the trigger position to the left in Edge trigger mode.

Perhaps there was an update which allows the trigger position to be moved to the far left while in edge trigger mode? Weird.

Hmm -- I may be misunderstanding the question? When you say "move the trigger to the left", you mean the left edge of the screen?

To my knowledge, this has always been possible with the DS1054Z, in any trigger mode, and it certainly is possible now. In fact, you can move the trigger point well beyond the left edge of the screen. The "delay" display in the upper right of the screen will then tell you the time difference between the trigger point and the time window visible on the screen.

For you, what happens when you rotate the "horizontal position" knob to the left?
