content: I imagine this has been asked before, but I couldn't find any answers here or elsewhere (theRigol DS1054Z-thread is pretty huge). Maybe its my lack of appropriate terminology.When I have captured a signal using the DS1054Z and try to adjust the scale (vertical or horizontal) or the position (vertical or horizontal) it first moves as I would expect, but after a few moves it suddenly refuses to scale or reposition. The settings gets updated but the waveform is frozen on the screen.When it captures a new waveform it works the same way - settings gets updated by waveform freezes after a while.I'm pretty new to digital oscilloscopes, so maybe I have misunderstood something, but it was my understanding that one of the benefits of a digital oscilloscope was that it can hold the waveform in memory and that you can scale/reposition it (within reasonable limits) once it has been captured.Thanks for any help and pointers, and once again, sorry if this has been asked before (probably)!Edit: This applies when the oscilloscope is set to Normal triggering mode and is waiting for a new trigger (i.e. green WAIT at upper left corner).

content: Any chance of a video? From your description, if I am understanding you correctly, I'm not able to reproduce the error, and I think my 1054z is just about the "buggiest" one around.

content: Either a video or perhaps set the 1054Z defaults and let us know what type of signal you're measuring or if it's the probe compensation signal. Then the steps you take and a screenshot of the waveform before you try to zoom in on it, then lastly what you're adjusting from there?

content: I am not able to reproduce the problem displayed in the video.I am running the latest version of firmware though - I suggest you upgrade your scope. The current rev is 00.04.03.SP1You can grab it here:http://beyondmeasure.rigoltech.com/acton/fs/blocks/showLandingPage/a/1579/p/p-0019/t/page/fm/0Despite the version it lists on the page when you download and unpack it you will see it is the newest.

content: Quote from: obbe on August 27, 2015, 06:50:53 amI'm also unable to reproduce this error. I'm running firmware 04.03 (no SP....)For sure this must be a firmware issue.Also the quoted firmware version you list was never made public from Rigol.

content: Thanks for your answers! Upgrading firmware did the trick!When I orded the scope last year there were some delays (yeah, I was pretty slow in fixing this issue). Perhaps Rigol shipped a scope that was not actually ready to meet deadlines? Or my supplier messed up somewhere.

content: Quote from: obbe on August 27, 2015, 07:43:02 amI remember that during Christmas time Rigol released a beta version to this forum, but it had a lot of other issues. Rigol was under pressure to get the jitter issue fixed.This bad firmware version was probably also installed on production systems during this time.
