Fungus,
Yes, it happen on all channels.
Signal square, DC voltage 13 volts, channel DC input
Ok, I'm going to say the oscilloscope is perfectly OK and this is just op-amp distortion.
13V into a channel which is set to 200mV will distort.
(and will distort much more in 1x mode than 10x mode).

I read about the overdriving, but no one wrote that this happens zero level binding disappears from the channel marker.
Is the zero level loss "normal" when overdriving DS1054?
My DSO203 for $ 100, I look on the same signal and it does not lose the zero level to the minimum sensitivity - 50mV.
It's a bad surprise for me.

"Zero level binding" isn't a real thing so you can't lose it and anything can be "normal" when you distort the input. It's undefined, it depends on the input signal.
You can set the volts/div to 'fine' control, this might let you see all the steps in between 1V and 500mV.
Edit: I just tried it on mine and I can reproduce this using the DS1054Z's built-in test signal if I switch the probe to 1x. Fine control lets me see it gradually.

The DSO203 op-amp isn't as sensitive as the DS1054Z

It's the reality of op-amps. It happens on all oscilloscopes.

Zero level loss from channel marker at 750mV for probe 10X.
So there it is, it's the input amplifier.

It no problem, is it the way it should be?
Sorry, I know very bad speak English. I hope you understand my question.
It happens like that on all Rigol Scopes. The Rigol front ends may be a little bit more sensitive to this than expected, especially so for the DS1000Z series since there is only one "hard switching point" between 500mV and 200mV (x1 range) -- when you can actually hear the relay clicking. All the other ranges are selected by the VGA frontend in the A/D converter. Thsi means, if you supply a rather high input signal and step from 500mV ro 200mV, the analog frontend amplifier is switched to high sensitivity and it doesn't need much signal beyond the displayable range to saturate it. I got trapped by that a few times as well but it isn't much of a problem if you get used to it. Of course, it's a handicap if you've got to zoom in on small details within a high amplitude signal. I guess here you've simply got to look at the price for the instrument and take it as an acceptable compromise. I'ts much more annoying that my MSO4000 isn't performing much better...
Got to use my venerable analog TEK 2465 if I've got to do measurements like that...
Cheers,
Tom

Should it be this way? That's a philosophy question.
Your oscilloscope is OK, if that's what you mean. This is normal behavior.
(but not
ideal behavior, we can agree)

Not only Rigol.
Has Rigol supplied a link to this firmware on any site other than its Chinese site? Is there any potential issue with installing the firmware on a scope purchased in North America? I assume that the firmware should be identical for all regions, but I don't understand why it's only showing up on a Chinese language site.
Rigol just isn't that organized, apparently, when it comes to their firmware release process. C'est la vie.
Folks here have installed it on NA scopes just fine.

I installed first the Chinese site, then the one that modified janekivi, to correct the error of spelling of "pluses" by pulses, probe back to install the original one worked and then I returned to install of janekivi, so everything perfect.
in spanish
yo instale primero la del sitio chino, luego la que modifico janekivi, para corregir el error de ortografia de "pluses" por pulses, probe volver instalar la original funciono y luego volvi a instalar de janekivi, asi que todo perfecto.
Hi,
I just updated the new firmware by janekivi on DS1054z
but still the system info screen is showing Ver: 00.04.04.SP3, Board Ver: 0.1.1
why is like that?
s8548a, the normal system info screen doesn't display the entire version number. To reveal more details, press in rapid succession, Menu -> Menu -> Force -> Menu -> Utility -> System -> System Info
Then, you'll see the full version information.
Thanks for the update, Miti. That took them a while.
I upgraded yesterday and I can confirm that the traces align better to the indexes... if you do the self cal after it warms up. I haven't seen any other "pluses" yet.
is there a download link where I can get the file without registering?

Have a look at the
Rigol DS1000Z Firmware/Buglist thread. OP always gets updated with the most current direct download link!
Would make a nice sticky here, but oh well...
Kind regards,
Frederik

Just type anything. It doesn't have any verification.
It’s not a new update though, it came out in April.
hmmm, yep. No need to get excited. Nothing new here. :-(
