Upgrading Mainboard in Lecroy DDA-3000 (aka WavePro 7300a?)

[Shef]

Привет всем! ( кому интересно смогут перевести! )

Купил себе DDA3000,  в штатном Железе, не устроило ! Решил переделать все целиком, попробовал более 10 материнских плат и 8 видеокарт!
Могу сказать на 99% что лучше всего работает процессоры Xeon и видеокарты от radion. Все остальное с определёнными проблемами. Так например - видеокарта gf 210 под виндовс xp показала себя хорошо ! но не отображает 3д корректно ( на моем канале есть материалы ) https://youtu.be/BTzPW9kjiDU

Ну, может быть, вы могли бы хотя бы добавить перевод Google в свой русский пост? В противном случае большинство людей не будут беспокоиться ...

Hello everybody! (anyone interested can translate!)

I bought myself a DDA3000, in the regular Iron, it did not work! I decided to redo everything entirely, tried more than 10 motherboards and 8 video cards!
I can say 99% that the Xeon processors and the video cards from radion work best. Everything else is with certain problems. So for example - the gf 210 video card for windows xp proved to be good! but does not display 3d correctly (there are materials on my channel

Has somebody figured out if the resolution of the xStream app can be lowered?

I installed a 2k IPad 9.7" screen, works beautifully. Touchscreen is extremely accurate. However, it would be more comfortable with less resolution.
The windows resolution can be lowered but it does not seem to have an effect on the xStream application

[sixtimesseven]

try restarting the scope/windows

Hmm, no that does not work. The XStream app just does not get the windows resolution settings but seems to set itself to the display setting.

[sixtimesseven]

try to find setting in utilities menu, display option or such...

Does not look like it... Is there another way to set the resolution in win 7 then the "screen resolution" menu? Some reg settings? I mean XStream has to figure out from somewhere what the resolution should be?

[sixtimesseven]

Changing the resolution to 64x480 via the properties/compability settings of the XStream app works. However, it is now 640x480 and there seems to be no option to adjust the compability mode resolution at all.
Somhow XStream ignores everything else and just resets the resolution as soon as it is running 

EDIT: Actually the scaling fits if I turn the resolution down to the original 800x600. However as soon as I get up in resolution at all the icons become tiny. The boxes shrink to a bit more than half the size.
800x600 is a real pitty for this 2k display. Althought I don't think there is any way to scale correctly and without mouse and keyboard the touchscreen becomes unusable.

I got my 7300A this week，it seem the mobo is newly version and support SATA .Only the problem is CPU socket is 478 not 775, So i plan to replace it to ASUS P5PE-VM with E5700 duo core cpu.

May I ask why this mobo and this socket?
You have to switch the display anyway. I do not see this pci type graphic interface on your new mobo...
I would upgrade to something with a single PCI and a 1155 socket, install an i5/i7 and upgrade to win 7. Performance boost particularly for things like fft are substantial and cpu / mobos of this eara are cheap (100-150 bucks, used i7 cpu, new mobo).

why does he need to change the display? with P5PE-VM actually no change to anything is necessary. everything about the display remains as it is
with a moderate/good upgrade to CPU and FSB. All current PCI cards fit in.
New mobos dont have the AGP slot anymore and going the PCI-E way, needs a few other cards as I understand (a graphics card and possibly a LVDS adapter?)...

You are right ！ Keep 865G chipset since it is last one support DVO via AGP bus, that mean you can keep all the card include LCD and Touchpanel . 775 version support dual core CPU also good for this scope.

Just for reference - the i915 chipset is the last, which supports AGP.  But I do not see the point of why you should strive for AGP. You just need to add any hardware to get the video output of the lvds (or parallel ttl for the old 800x600 display).

A good example for replacing a motherboard I mentioned:  HERE
This is an AIMB-582QG2 motherboard that already contains integrated PCI, LVDS and DP ports.

Hello

I just came across your talks and it's very interesting!
At what price did you manage to buy your used models ?

well, try to find that motherboard on ebay today 
but let's say some time in future I get lucky and I can find that motherboard cheap, can you please tell me exactly what other hardware I will need if I want to keep the original LCD (i dont like ipad lcd or any hd quality because I wont be able to see/read the screen. even at 800x600 I have problem)

my second question is, what will be the software installation procedure? is this correct: (1) install winxp (with multiprocessor HAL) (2) install Lecroy drivers and touchpad driver (which ones?) (3) install latest XStream software (4) workaround for front panel LED flashing

thanks

The native LCD matrix NL8060BC26-17 has an parallel ttl-interface 1 ch, 6-bit, 41 pins Connector DF9-41. You just need to use the scaler module, which is compatible with it and which you will connect to the output of the GPU (built-in MB, or a separate discrete one). Either use a discrete graphics processor with an integrated 6-bit ttl port to connect your matrix, or use a motherboard with an integrated 6-bit ttl port to directly connect your matrix.

   I get problem with P5PE-VM mobo , the OS will hang on power off  screen, I tried both XP and Win7 ,and reboot is function properly, Anybody has same problem here ?  Maybe ACPI drivers was problem or mobo had hardware issue .

[lzqing]

  It is CPU 's problem , if i use E5700 will be report uCode error and getting this shutdown issue.It is ok now since i change back to P4 CPU.
I Still working for install Xstream drivers for my 7300A with P5PE-VM base on Win7 OS, i tried many times and reading this post , i think it is very simply ,but  all the solution not working for me .

that cpu is not officially supported by  this board. you need the unofficial modded bios.

So I got an idea to try upgrading my 6030A scope; I found an AIMB-582 board for $30 shipped so I figured it was worth a shot. It's a Q77 board with 2x PCI, 1x PCI-E 16x and 1x PCI-E 4x. It also has a LVDS port on the board itself.

I figured the USB probably wouldn't work with the onboard ports based on other posts so I went ahead and picked up a PCI-E USB3.0 card with a 20 pin internal header and a USB3.0 20pin to USB2.0 10pin adapter cable.

I went with an i7 3770 (non K since I don't plan on overclocking it) and a Noctua 65mm tall cooler; first issue was the backplate on the AIMB-582 is designed to be used with an Advantech cooler; I bought a used LGA115X cpu socket + backplate off eBay for $8 bucks and replaced the Advantech backplate with a stock one and the Noctua HSF went on fine.

I installed 4GB (2x2 GB) of DDR3 and got the board mounted in the case with no PCI cards; second issue was the PSU 20pin cable, too short. I removed the PSU and got it plugged in so I could install Windows and ordered a 24-pin extender (20 pin extenders were a few week wait). Got the extender and everything worked fine.

At this point I installed the PCI acquistion card, the PCI GPIB card and the PCI-E USB3.0 card and hooked everything up. I also made an AC97->HD Audio cable to plug into the motherboard for the front speaker on the 6030A. This audio works OK playing music and stuff, but there is still some feedback, not sure what exactly is going on but I'll probably just disconnect it since I don't like the audible feedback feature anyway.

Got the latest XStream 8.whatever 32bit version installed and bam, everything worked great. Front panel has no issues plugged into the PCI-E card; even the thermal printer that my 6030A has works perfect. It's way faster now, since I moved it from a 2.8GHz P4 to a i7 3770 quadcore, so that's to be expected.

Cost overall was around $160 total, the majority of that being the CPU so I'm super pleased with how it turned out.

Overall, a few things left; I lost the CD drive since it was IDE and the 582 board only supports SATA, easy fix, I'll eventually get a slimline DVD drive to put in there for completion sake even though I've been using USB for everything.

The last big hurdle is the internal display; I've pretty much always used a 22" 1080p monitor stacked on top of the scope since I like the bigger screen so I'm not in a big rush to do the internal display. Reading here seems like the 6030 has a parallel TTL type connector; digging around on the back of the front panel on my 6030A I've seeing a TI LVDS receiver chip that is feeding the actual display connector. The old AGP card had a LVDS transmitter chip on it that brought out 3x data channels and 1x clock on a 20pin that goes to the front panel PCB into another 20 pin.

Looking at the LVDS chip that the AIMB-582 board is using and BIOS options it looks like I can set the port up for 18bit 800x600 (matching what I believe is coming out of the AGP card in my 6030A) so I'd just need a 40pin to 20pin LVDS cable pinned right for the A0,A1,A2 data and clock? I've not messed with LVDS before so I could be wrong, not sure if someone else has tried this on an 6kA model before.

It turns out the factory calibration is also in the EEPROMs on the acquisition board so you don't need to save the files. A self calibration from the service menu does the rest to restore all the calibration data.

if original owner did a calibration process later during the life of the scope in service, will it saved in eeprom too?

You'd have to ask Lecroy. I'd assume if you send it to Lecroy then they might update the EEPROM values if necessary.
It seems the self calibration data is saved in different files. The data which is in the EEPROMs is read once if the file is missing on the disk.

I think LeCroy (at least its US headquoters) save copies of all calibration data done in the last 15 years of so. So if your scope is not too old or it has been back to them for re-calibration, you can call them and request them to email you a copy of the calibration files. Easy.

I think you have an SDA6000 (only 50 ohm inputs, right? no 1M). What version of the lecroy xstream are you using?
what options do you have on your scope? I have a 7300A but it does not have the "spectrum analyzer" package. of course I have FFT as part of math functions but in your last picture you have a dedicated spectrum analyzer tool. I am curious how I can have that on my scope. what option can enable that tool?

yes 50 ohm input. latest ver8... you can download from lecroy website (google XStreamDSOInstaller), but in order to add licenses, you need to do it in older ver7.x (i guess the ori xstream installer comes with your DSO saved somewhere in the HDD) after add licenses, upgrade to latest version 8, you can stick with older ver i dont find any problem, except i like the spectrum (FFT) (and 3D iirc) windows arrangement on the latest version. read this thread VERY carefully... https://www.eevblog.com/forum/testgear/lecroy-options-recovery/ its not straight forward at first and learn the way how mr jack sparrow talk and think. really, you need to search here in eevblog for "Lecroy mod" "Lecroy dso" etc, there are many infos here.

Nice! So I went to this thread and generated a list of options for my scope. Can see "SPECTRUM" option available among many other interesting choices. Now I need to take a look at them. My scope multi-boots between Linux, XP and Win7 and I have X-Stream 8.1.0.1 (XP) and 8.6.2.10 (Win7) installed. Do you say that I have to go back to 7.1.x to apply the generated keys? Or newer X-Stream already converted my eeprom to different format so this keygen's is useless for me? Re-installing 7.1 is not a problem and is totally worth to try the new options...

Slightly of topic but:

Could a WaveMaster 8500A owner take a good, head on photo of the label on the front panel. The "WAVEMASTER 8500A 5GHz 20GS/s" one on the front?

My DDA's label is messed up and I thought I change it to Wavemaster to reflect the software changes.
I can straighten slanted photos but on the web I only found low res Photos of the 8500 front panel which are of no use.


Edit: Attached sample pic.

[albertr]

Overwriting the EEPROM in the input module does not significantly affect the bandwidth of the oscilloscope. But I found elements in the circuit, which change WP7200 to WP7300. Each WP7200 or WP7100 can be changed to WP7300. It turned out to be easier than I thought.

Nice! So front ends are identical besides a few passive components? Can you share the details on how to mod 7100 into 7300?
Does it affect calibration?

Just got my DDA-5005 from E-Bay and shipped from Thailand. It was listed as untested and was running on the pictures taken for the offer. One price offer later I was proud owner of a DDA-5005A XL.

I did my homework in advance and found this awsome forum with tons of info and tools to get this units working again even if they are broken.
Just a short shoutout to this community: Thanks to everyone contributing to this topic and sharing their knowledge, experience and work. All this helped me with my first babysteps getting this unit disassembled and basically tested.

And this is where my journey starts:

I got the unit well packet with no damages on the outside beside on of the feet on the back. The Unit seems to come from Maxtor (last calibration 2013). The Unit was built in 2004.
The first external inspection shows no wear on the front connectors and no other damages from a longer storage. My mood was getting better and better.
Next should be the first Power-Cycle. This unit boots nicely and the HDD had no click of death so far.
X-Stream starts nicely too and this where I am not sure what I see:
All four channels semm to work and if I switch to 50R termination I get a signal on all four channel 
Channel one Sine, channel two sqaure, channel three rectangular and channel four puls. Alls signals overlay and have a base frequqnecy of about 3 MHz. Is this some Kind of reference/calibration signal ?
As my LPA-SMA adapter are on their way and will arrive later this week, i can not give any signal externally to the channels.

After opening the unit I inspected the mainboard and internal fans:
- Mainboard has some blown caps
- not a lot of dust inside --> nice
- after removing fan of cpu cooler ther was some dust so maybe it was cleaned one time.
- two screws are missing inside from the mounting plate of the two big fans in the front of the unit. Somebody was in here before.
Maybe from calibration ? Maybe they have been replaced.
- PSU does not make funny noises so far (will be checked and Caps replaced)
- HDD has both partitions and it seems that all info is present on second partition

Maybe you guys can help me on my way pimping this unit and getting it back to old glory. First step would be understanding this signals displayed.
I hat a peek inside the Service Menu and hat a look in the communication errors to the subsystems and there were no errors. First thing in my mind would be that his is good news.
What should be the first test to find out what is going on or should I first go for hardware upgrade (Mainboard and HDD) ?
I will take some photos of the unit and upload it when I work on it next time. Let me know what to take pictures of.

Here is what I want to do on the unit:
- Upgrade Mainboard / CPU with one that has at least SATA (Not sure if i want to go for Mainboard without AGP and new display or "old" graphics-card)
- Upgrade to Win XP or later (not sure so far what will be the hurdels)
- Upgrade of X-Stream
- maybe try to get licences running
- Fan replacement of the old turbines

What I have in my lab:
- Spectrum analyzer up to 3.5 GHz
- Oscilloscove 500 MHz WaveJet
- Signal generator
- Counter
- usual stuff (multimeter, cables, adapters ....)

[analogRF]

If I am not mistaken, these scopes have a demo mode that shows signals on 4 channels. I haven't tried it myself before but I think it is in there
there should be something in the menus. OR maybe it is showing some reference signals that had been stored before.
Just put the scope in its factory default state

Isn't it already running windows XP? What is the motherboard model?

If you want to keep the changes to minimum (as I preferred) and keep the AGP and do just a moderate upgrade
unfortunately the options are very limited for motherboard. The only think I could find was Asus P5PE-VM
like this guy http://s-audio.systems/blog/lecroy-upgrade/

if someone can point to a better option for mobo (to keep the AGP slot and 2 PCI slots) please do

[BeckGyver]

I searched for the "Demo Mode" but could not locate. There are some Scope-Settings and I reset to those but had the same waveforms.
I assume these demo waveforms are stored data and not a generated waveform fed to the inputs. Therefore not a real test of the frontend.

The Mainboard installed is a Intel D845GERG2 - I have attatched some pictures.
I have an Asus P4P800-VM with 4gb and P4 3.2GHz HT available and would like to throw it in together with a ssd and go for a full re-install on Win XP. But befor I go this route, Prio1 for me now is to find what is wrong with it (and it seems so from my feeling now).

Unfortunately it has been Win2k on production.
I am not afraid of going deeper into the scope and change it to other mainboards and change screens as well, but would like to go step by step to not enter the rabbit hole with light speed.

I have access to all the files in driv D: and will go for a DD and recover to se what was in there befor it was dumped. I can also get the logs from service menu, please let me know which is the right to look for.
