Rigol DHO800/900 Oscilloscope Bug Reports + Firmware

[ebastler]

Is this running the latest FW 00.01.02.00.02 ?

Does that imply that you have achieved faster recording rates with the latest software? Could you please summarize what you get? Thanks!

Alltough you have to create a account at the rigol site, which did not work at all, to download the firmware, i managed to get it from another source. Yes it is running this firmware.

None of the major bugs i stumbled upon were fixed...

[ebastler]

By the way: I am not aware that a login is required to download Rigol firmware from the official site. I found the product pages to be better organized than the "support" section, and they also include manuals/firmware/software.

On the product page, scroll down a bit until you get to the white section of the page, then select the "software & firmware" tab: https://int.rigol.com/products/detail/DHO800

[eTobey]

That did NOT work here:

What a mess it is!

First product i bought from Rigol, and i think it will also be the last...

[eTobey]

The signal is good when it runs, but when i stop the acquire, it gets messy (see picture). Is this a bug or a feature? Persistance is set to min

Is Gear/Display/Waveform Freeze set to On or Off? If it's ON, try it in the Off position.

[ebastler]

I am not sure whether you are concerned about decoding or about the trace display itself. Assuming it's the trace rendition:

The DHOs let you choose whether, after stopping the acquisition, you want to see only the most recent capture, or want to "freeze" the intensity-graded overlay of multiple sweeps. The latter is the default, a bit unconventionally. You can change this in the display settings, see section 19.8 of the manual.

There european site is a simple mess. We already had that here. Get the firmware in the U.S. - this is working without login.

 Why would i want to see intensity when stopped, if i had not set it up before? That is stupid, but at least this stupidity can be turned off. 

[eTobey]

Bug: Trigger is off big time..
Its kinda hard to work on a prototype with a chip that you dont have much experience with. Yet here comes rigol, making your day even harder:

Maybe they wnated to make sure that all users realize the DHO has that capability. 
But once you turn it off, the scope should remember the setting, so it won't bother you again until you ask for it.

Don't be too harsh on your new scope and on Rigol. Always look on the bright side...   On the other hand, if you really find that the scope does not do what you need it to do, there's still time to swap it for something a bit less shiny but more serious...

If I remember correctly.
According to the factory settings, it does not load the last one, you will have to change it first.

Yes, yet another stupid default setting...

I was shocked the first time when i started it the next day, when all settings were lost, because i thought there would be no such option. Funny enough i need to restart it, when i want all setting reset, and wait 53 secounds?

It's debatable whether "restart with factory defaults" should be the default setting. But having that startup mode available certainly makes sense in environments where the scope is used by multiple people for different tasks, and most notably in education & training use.

And of course restarting the scope is not the only (and slow) way to get back to the default settings. There is a dedicated button for that, part of the hexagon in the upper right. Press it twice, or press once and confirm in the touch-screen menu, to return to the factory defaults quickly. 

[Fungus]

Or just press this...

[eTobey]

Persistance is not persistant on first few triggers:

I have some signals, that appear about every 0,5 to 1 s, and the div is set at 10us. You can see the first signal beeing triggered, but they dissapear immediately. Only after a few of those they stay. Persistance is set at "infinite". The trigger is a simple falling edge.

So persistance is not working, recording is not working and ultraacquire is also not working.

This Rigol rubbish is definately going back. Cant even do simple things reliable.

Here's an idea for you, Fungus: Why don't you try and make it a habit to read the following post or two before you fire off a reply? 
It would improve the signal-to-redundancy ratio of many threads quite a bit.

[eTobey]

Or just press this...

It would help a lot if you would actually read a few more posts, to not parrot from other users, or to just comprehend whats going on. You already stood out for me like someone that creates more confusion as really helping. Just like in my noise problem thread...

then why you post this mourning if the default button is not what you want?

[shapirus]

BTW, is there any way to disable the Auto button?
It is very annoying, as it doesn't request confirmation before proceeding. It is quite easy to press it accidentally. It is ridiculous that scope manufacturers (not only Rigol) waste front panel space for this button, and for Default as well, instead of moving them to an on-screen menu. Luckily, the Default button does at least request confirmation to proceed. It's still not impossible to press it twice accidentally though.

[ebastler]

then why you post this mourning if the default button is not what you want?

The info about the Default button was relevant for eTobey, I think. But coming from Fungus, it was also redundant, since I had just said the same thing -- in the very next post after eTobey's original complaint, and right before Fungus' post.

Which is quite often the case with Fungus. He seems to be in the habit of firing off a reply as soon as he sees a post, not bothering to read even a single following post to check what has already been said.

[ebastler]

BTW, is there any way to disable the Auto button?

You can disable/enable it via a SCPI command, :SYSTem:AUToscale <bool>.

I think Rigol deliberately hid that option in a SCPI command with educational settings in mind: The teacher can disable AUTO for his students so they learn how to set up the scope on their own, and they can't easily re-enable it.

I was just on this point a few hours ago... There is a button to revert that. But you better dont miss that button! I missed it  ... Really frustrating.

I sometimes have the feeling, that touchscreen behaves a bit strange. Missing buttons and closing windows. Might be some electrostatic problems?

[eTobey]

My waveform dissappeared. Just catched an error... 
I did not use vernier, like dave did in the video.
I was just scaling and moving it time wise.

Anyone knows how to avoid this problem, or where it happens?

This bug was documented by dave 5 months ago! And yes, i have the newest firmware.


 

[eTobey]

Level of trigger is not saved when turning off....

This is even worse than saving nothing at all, as you would not expect this, and then you may end up looking at the board... 

Edit: Even the hex format is lost. I could live with this, but still its so poor.

First days i thought "not so much complaining like with the owon", but today i realized, that i just was to slow to find those problems.
