Rigol's New DHO800 Oscilloscope unbox & teardown

[ebastler]

Depends on the specific model, I guess. DHO914 is supposedly in stock at Batronix, and lead times for DHO800 are shorter than other DHO900 models.

So everybody is going for the DHO900? That's interesting...
Is it the color? The bandwidth? The Siggen?

I don't think we can derive demand from the lead times. Maybe Rigol produces much more of the 800 series but did not estimate the balance quite right; maybe it's just the departure and arrival times of separate containers and ships?

Personally, if I should decide to get one of these small DHOs, it would indeed be a 900 model since I want the mixed-signal option. "Just" the 12 bit capability and touch screen alone would not be a sufficient step in functionality to justify replacing my old DS1054Z. And while I'm at it I would probably pick the 914S to also have the signal generator & Bode plot, just in case...

I had an email discussion with eleshop. They are entirely dependent on the decisions Rigol makes. Sometimes, an ordered batch just  doesn't come through. I think Rigol hugely underestimated the popularity  of both the 800 and the 900 series .

How do you guys in the Europe get your DHO800/900? I ordered from Batronix and they tell me the ETA will be mid-December  .

Depends on the specific model, I guess. DHO914 is supposedly in stock at Batronix, and lead times for DHO800 are shorter than other DHO900 models. Other dealers might have different stock? The socially accepted method in Europe is to check dealers' websites for stock/lead time info, or call them or send an email if that info is not provided online. 

Are you really in China as your country flag suggests? Why would you order from Europe then? 

Ah, I'm an expat in Switzerland.
I ordered DHO914S btw. Batronix has changed the lead time on the website several times, once it shows the stock is 3-7 days away, but then changed back to 21-40 days. DHO914 is exceptionally in stock currently it seems.

In my case was the MSO.  Not using it and no probe, but it is there in case you need it in the future.  I prefer PC based logic analyzers and I have several of them, but for some extra $$$ you can have it integrated...

According to the website, the DHO914S is in stock here: https://rigolshop.eu/dho914s.html
Better take that with a grain of salt though and check with them before you consider cancelling your Batronix order...

I'm fairly sure they didn't. 

The problem is that they have to supply the entire world and I doubt they're going to build extra factories just for this because demand will eventually level off. Better to have a supply shortage for a couple of months...

Has anybody managed to install an FTP program on one of these? FTP access to screenshots is incredibly useful on my Micsig.

The scope is running an ftp server. You can

ftp scope-ip-address

or just use adb:

adb pull /data/UserData   [to copy all the screenshots]
adb pull /data/UserData/RigolDS22.png  [to copy RigolDS22.png, etc.]

[Fungus]

The scope is running an ftp server. You can

ftp scope-ip-address

I haven't tried that... I'll give it a go later.

Update: Yes, it works!

Now I can easily grab images in PNG format.

Is the smell worse or better than 1054z?

Is the smell worse or better than 1054z?

It was quite bad out of the box but it's pretty much gone now.

I left mine switched on for a few days in the spare room (to keep it warm) until it went.

I just noticed the stats are reset when the 'scope is running and you change the vertical scale or horizontal time base.

Add that to the long list of ways to reset the stats that are better than having to manually reset them on other 'scopes.

This is a completely normal and logical behavior, as I know it from dozens of other scopes.

You just can't help yourself aren't you?.. You keep calling making fool of yourself... No matter how many times I try to teach you...

Thank you,hubert.
My DHO804 is DHO924 now.
Two extra drams are only for LA.It can be unpopulate if doesn't use the LA .
The bandwidth is increased successfully.it has 800ps rise time now.
And the memory depth is 50M now.

Hi，I have a 804 now,I want to crack but I don't know how to do that.Can you give us some operational procedures?Of course need x.bin but others.

The current preference is not to turn the DHO800 into a DHO900, because that has caused offset problems in several units. Rather, the DSO800 options for 50 MPts memory and 100 MHz bandwidth can be unlocked as described in the post I linked to. There is, however, no known way (yet?) to go to 250 MHz bandwidth and to enable the CAN and LIN decoders via this approach.

But the "100Mhz" option seems to give 200Mhz of bandwidth (measured) for some reason, so...

Next up: WiFi.

Can anybody recommend a known model of WiFi dongle that works with these?

Aliexpress is fine.

This one should work... since rtl8188 works with most Android and Linux systems.
Floydfish already proved that previously.

Also, there are several versions with an external antenna exist... Aliexpress / Amazon.

I'll give it a shot.

People complain about these only having one USB port but I can grab files over HTTP or FTP so I don't need a USB stick, I use a stylus instead of a mouse, that means the USB port is mostly free at the moment.

One less cable is good, especially if I want to use it on the other side of the room.

I'd appreciate it if someone who already has DHO900 with LA and caliper could make four precise measurements. #3 and #4 are the distances between the front surface of the scope shell and the plastic edge of the IDC socket, both sides should be measured... it seems to me the right side is slightly higher than the left.

I'm trying to adapt/design a nice-looking shell of DIY LA for new DHO scopes.

how do you watch movie in your scope if its on the other room? or play tetris? over ftp? mine is less one cable too... ie usb cable without ethernet cable... and i can still watch movies and play games

[Fungus]

On my Micsig I used to go to youtube.com or copy the video file onto a USB stick. They support most video file formats.

since i had a spare Wifi dongle i was also trying to use it with my DHO804. Without success so far.

In linux the Wifi dingle shows up as a:
0bda:8176 Realtek Semiconductor Corp. RTL8188CUS 802.11n WLAN Adapter

So it's a RTL8188 but an CUS and not EU.

I put the dongle into the oscilloscope first, turned it on and and started the android settings app with:
adb shell am start com.android.settings

then i tried to activate the Wifi in the menu, but it didn't turn on.

Did i do something wrong? Is there another way? Or is the  RTL8188CUS just not supported by the driver?

Yep, this driver doesn't support RTL8188CUS, since it used the 8192 chipset and it requires 8192cu driver.

The list of supported device IDs by 8188eu:
056E:4008 Elecom Co., Ltd (Device name unknown)
07B8:8179 AboCom Systems Inc (Device name unknown)
0BDA:0179 Realtek Semiconductor Corp. RTL8188ETV Wireless LAN 802.11n Network Adapter
0BDA:8179 Realtek Semiconductor Corp. RTL8188EUS 802.11n Wireless Network Adapter
0DF6:0076 Sitecom Europe B.V. (Device name unknown)
2001:330F D-Link Corp. (Device name unknown)
2001:3310 D-Link Corp. (Device name unknown)
2001:3311 D-Link Corp. (Device name unknown)

-------

PS: It looks like some Chinese wifi dongles use RTL8188FTV chipset, so to ensure compatibility with the scope it'll be better to order the exact RTL8188EUS (RTL8188EU) or RTL8188ETV

Also be careful with TP-Link TL-WN725N which someone advised as compatible, since it has 3 versions... V1 uses RTL8188CUS, and V2/V3 use RTL8188EUS
