New Rigol HDO1000 12-bit DSO - BUGs

[skander36]

Hi alex-lab,
I'm not sure that all are bugs as I didn't succeed to recreate all but please keep posting these findings here.
Thank you!

Has anyone been able to get the video triggering working on a PAL or NTSC signal?

I can't get it to work here...  (see images attached).

It works OK on my old DS1074Z with the same signal... Did I miss something?

Did you ever find a resolution to this problem?

Here's a peculiar one:

Conditions:
- DHO1074 (200MHz and 100MSa options enabled), F/W 00.02.12
- Only channel 4 enabled
- 10MHz fast-rise square wave of 2.5Vp (ground-referenced) coupled to channel 4 (1V/div) and to EXT Trig input (correctly terminated)
- Trigger engine configured EXT, rising edge, 1.25V Threshold, "normal" mode
- Memory depth "Auto", but 1MSa "works" as well - others not tested

Findings:
The scope won't trigger if the time base is set faster than 50ns/div or zoom is enabled faster than that and becomes very sluggish to respond to user inputs. At 50ns/div or slower, everything works normally. This peculiar behaviour isn't present if another channel is used. Also, just enabling another, additional channel will return the scope to "normal" operation. Triggering on channel 4 works completely normal, just channel 4 and external trigger shows this behaviour. It appears that "playing around in menus" may resolve this problem eventually though I'm not sure what operation in particular causes this. After a fresh reboot, the described problem returns.

More findings:
In Trigger menu with "External" trigger source selected, the "50%" button should be made inactive since it only resets the trigger threshold to 0V. The trigger threshold setting appears not to be very accurate when the external trigger input is used - I find the scope to trigger well between approx. -500mV and +3.5V threshold setting when I apply my 2.5Vp signal. Maybe the ~100ps edges affect the external trigger circuitry.

Web Interface:
Did anybody notice that when using the web interface, the browser window size gets "automatically" reset every now and then and as a consequence, the scroll bars get enabled and obstruct some of the screen area (very annoying). I want my manually resized remote scope screen to stay that way... It even resets the screen size to "window" if "full screen" is selected!  Machine is a Windows 10 PC with Firefox browser, but a test with Edge shows the same problem. I'm not too much a Windows expert to know if this may be solved by browser configuration, but a quick scan through the setup menus didn't show up anything that might help (at least to my understanding). Any hint appreciated  !

- DHO1074 (200MHz and 100MSa options enabled), F/W 00.02.12

Is that a typo for FW 02.11 or did I miss a new version?

[TurboTom]

Available here: https://www.rigol.com/products/detail/DHO1000 (chinese page) and click the third button just beneath the big presentation picture with the dark background.

Thanks!

I wonder why it is so hard for Rigol to publish firmware updates consistenty across their international sites. And to put release dates on the website which actually describe the release date. (FW 02.12 contains files generated on October 18th, so it probably was not released in August as stated...) And maybe make release notes accessible on the website, so you can review them before downloading the whole firmware. -- Sigh...

I'm trying to update my firmware on the DHO1074.

The firmware from Rigol is DHO4000Update.GEL - am I supposed to rename this?

Just copy it as is to USB, it should detect. If not, might need renaming.

[joeyjoejoe]

It was not detected. I'll try renaming

[joeyjoejoe]

No luck. I guess I'll email Rigol? It saves screenshots to the USB disk no problem. I'm using the one next to the power button. Renamed to 1000 still no file found it says.

[thm_w]

It was not detected. I'll try renaming

The file name should be "DHO4000Update.GEL" as per: https://www.eevblog.com/forum/testgear/dho1000-missing-gel-file-in-0-2-7-upgrade/
edit: see below use storage function to upgrade. normal upgrade menu might be some kind of web based one.

Did you select the file from the list, can you see the file name in the firmware update box?

[joeyjoejoe]

Nope I hit upgrade and it just says no file found. Don't even get a chooser. I'm hitting the icon in the bottom left of the screen and choosing upgrade

[Fungus]

On the DHO800 you have to go to "Storage->Upgrade"

The same for my DHO804.

I think a bug - Every time I power up, the attenuation on my probes is set to 1X and I have to set it again. I have not seen any options to save this setting between power cycles. DHO1074

Tap the date in the bottom right corner -> Setup -> Load last = Last

A couple of things that I noticed were not saved by selecting the "Last" setting.

1. Screen Brightness - I set it to 50% and it always goes back to 100% on bootup
2. External 10MHz Reference - I have to turn it on each time the scope is booted

[Fungus]

1. Screen Brightness - I set it to 50% and it always goes back to 100% on bootup

The DHO800 is the same. Try setting the trace intensity to 100% then reboot twice...

There seems to be a bug in the statistics feature for the DEViation figure when choosing larger than 1k counts, at least for the rise time measurements.

I just wanted to verify a bandwidth upgrade on my DHO1074 with FW 00.02.12 when I saw that the deviation figure for the risetime measurement statistics with 10k counts maximum was very solid while the number of measurements was counting up, but the dev figure started to rise continuously without a cause once the 10k were reached. I could replicate the error several times, at least with 10k, but I assume any number higher than default is affected or the effect is more pronounced the higher the maximum count is set (kind of a hardcoded 1k count in the calculation once the limit is reached).

So better to either stick to 1k or go with 100k to be on the safe side and take the reading as long as it is below 100k.

EDIT: set it to 100k, door bell rang, came back about 10min later with counter at ~15k and DEV was at 0.000. So there is some other bug as well

DHO1074 with v2.04 FW just arrived. I renamed the new v2.12 FW file from dho4000... to hdo1000... and that worked like a charm.

I went through the Storage->Disk->File menu sequence. The Upgrade Button worked fine with the original file name.

What was your FW before updating to v2.12?
My dho1074 with the original v2.04 didn't recognize the update file dho4000 until renaming.

[t3chiman]

Apologies, I am repeating from a prior thread. I got in a DHO1074 from RigolNA. Firmware was 04.02.02 before upgrading, initially to 00.02.11, then to 00.02.12.

Just an observation: Rigol's firmware upgrade procedure and  release control management are both "unsophisticated". A bunch of talented and motivated engineers--the eevblog team--experience hesitancy and confusion during what should be a naive button pushing exercise.

Was able to reproduce but not in the same way:
- Turn on CH1, 1V/div, 1us
- Turn on AC RMS, Vamp, and RiseTime measurements
- Tap measurement, setting, change counts to 10000
- Dev for Vamp (second measurement) shows as 0.000V
edit: I removed and re-added Vamp and it still showed as 0.000V. So it doesn't matter what position the measurement is in on the screen. Removed it completely and another random measurement shows 0V

Did you report to Rigol?
