Yes I understand that as I have been following this thread for about a year now, I'm just providing information that I think people might find useful.

I purchased the parts to upgrade the computer in my scope about 10 months ago:  AIMB-581 MB and NEC NL10276BC20-04 LCD.  I finally made an LVDS cable for the MB and did the upgrade to Win7 right after my last post here.  I used DXL's modified drivers for Win7 and had no trouble installing X-Stream 8.5.1.1 32-bit.  I don't think it really gains us much over 8.1.0.1 / 8.1.2.0, though.  I think the main additions are for features that our scopes lack the hardware to support like triggering on protocol decode.

What are you trying to reach ??? DDA was an 'option' on top of the WP... you could eventually try to wipe that one in service mode, but I'm not too sure this is sufficient ??
For the Zi series, DDA option is 01-04000000, but it might be different for the WP7K... but anyway, in service mode, you should see which key enables 'DDA'...  but again, not too sure what you expect from this...???

I only interesting. Now i have WP7300. But i see some pictures from WP7300a. So i think exists option for identity device as WP7300a and also use -XXL memory. Because -XXL only available on WP7300a.

I believe the A series also comes with a different main processor (maybe the motherboard as well, though both of these changed over the sales lifetime of the scope), and it probably comes with a different 10GHz generation and distribution board - the jitter spec is notably lower than the regular series.

I guess there's a chance it's just a better internal timebase or lower phase noise VCO, though, in which case the board could still be the same.

I want solder memory for -XXL option and need know option mask for 'A'. Other not need ))

If any have 7x00a, please let know, which options installed and if possibly memory type.

'A' is not an option mask on the WP7KA family and the memory, the MAM, is proprietary technology as far as I am aware.  This is getting off-topic for a thread about upgrading the MB...

No -A can be marked by license. bucause I have a -A scope before. but when I change another 1-wire EEPROM with more licenses, the -A mark dissapear!!!
If anyone who have the origin 1-wire EEPROM image with A-model. please notice me. Tks!!

What model was that for?  The WR6K and WP7K families do not have an option to turn them into "A" models.  There does exist an AMODEL option but it only works for WM8Zi and LM9MZi as far as I know.   Both my 6050 and 7300 are "A" models and neither have an option for it.

I've been looking at the cal data related stuff in firmware a little bit and started a thread about it over here:
http://www.eevblog.com/forum/testgear/lecroy-x-stream-calibration-data-and-storage/

Looking back over this thread I would like to correct some old posts and explain "weird behavior" for the benefit of anyone swapping out their hard drive.

I had 20G drive C:, and 20G userdata (which contains the calibration data). The userdata partition was contained in a logical partition. Just moving the partition content to a primary partition with dd on linux made the software complain that the calibration data was moved.

Partition type doesn't matter -- it's looking for a drive letter D: with a volume name of USERDATA.  You probably just didn't set the volume label when setting up the partition from Linux.

Yes, got exactly the same message. I've now recreated the logical partition, and moved that to the end of the disk. So the position on the disk in terms of sectors doesn't matter, but the partition numbering does.

See above.  It can even be a separate disk as long as the letter is D: and the volume name is USERDATA.
Firmware calls GetVolumeInformationW with a root path name of "D:\" and checks the returned volume name for a match to USERDATA.

I'm not sure whether it has to be on a logical partition. I would rather think that they store the partition location during calibration and so it can't be moved later.

That is not the case.  The possible locations are hard-coded.  First it will look for a D: drive with volume name USERDATA and if that fails then it will fall back to C:\LeCroy\XStream for the Maui root path and C:\LeCroy\XStream\Calibration for the Maui calibration path.

Well, it's rather interesting... I changed my calibration partition to be the second partition. Tried as both physical partition and as an extended partition. Formatted as either FAT32 or NTFS. Still getting the same error. Obviously, it's always mounted on drive D:\ and has "USERDATA" as a volume name. I have verified that XStream is reading and writing the config files to this filesystem. In fact, I can back up and restore the calibration data back using XStream "Critical files backup" procedure which is the official procedure to restore calibration data when changing the hard drive. I'm starting to suspect that it's going to be something else... what am I missing?

The "unidentified structures" messages at bootup means that some data points in the BTD files were not filled out.  It appears these are not critical errors but everybody notices them for the first time when troubleshooting the nasty popup message and believes they are related when they are not.

If you don't have a Calibration folder at the right location before firmware starts then you will get the popup message.  Once you answer either yes or no, it will set a registry key (HKCU\SOFTWARE\LeCroy\Maui\ShowCalibrationDataError) that will either always show the popup or never show the popup.  So it will keep coming back even after you restore the cal data!  To make it go away, just delete the registry key (instead of setting it to 1 or 0).

Also, my calibration issue is somehow resolved after installing XStream under Windows 7. I'm using the same calibration partition mounted as "D:\" drive in both Win XP and Win 7, but after installing XStream software under Win 7, I'm not seeing this error any more. If I re-boot back into Win XP, the error comes back. Weird...

That's because the registry key exists in the XP registry but not in the Win7 registry -- you already had the D: drive set up when you installed Win7 so you never got the message box and never added the registry key in Win7.

Do you mean I simply need to create a C: and D: partition? Or is there something more specific I need to do?

Your options are to create a D: partition named USERDATA, install a second D: drive and name the volume USERDATA, or you can just ignore that step and run on a single C: drive.

I think to avoid the prompt in the first place you need to create the D:\Calibration folder or the C:\LeCroy\XStream\Calibration folder before launching firmware, but I wouldn't worry about it.  Just decide if you want a D: drive or not for your calibration and save files, set it up if you want it, install firmware, restore your cal data, and then delete the registry key that makes the popup always show.

I actually did some thorough looking at the registry. I looked through everything I could find with "LeCroy" and there was nothing about cal data, location of it, or even that the message should appear/not appear. Very little in the registry from what I could find.

You were looking under HKEY_LOCAL_MACHINE but the setting you were looking for is under HKEY_CURRENT_USER :P

I WONDER. My scope is a WaveRunner 6100. Perhaps your is different and therefore produces different files?

From what I can see in the firmware, no.  I believe all the XStream scopes are using the same calibration methodology with the same named files and data structures inside.  It's a very small amount of data stored at a single operating temperature so corrections for all other operating points would have to be extrapolated.  My guess is that the extrapolations to other operating points are stored in the cache files for faster lookup the next time and the caches are not part of the critical files backup.

Interestingly, today I decided to log in using LeCroyUser and to my amazment, when I run Start DSO, I do not get the error message!

That is because the registry key that FORCES the message to appear on every launch of firmware is stored under HKEY_CURRENT_USER.  Log in as a new user and the key is gone!  As long as the calibration folder is in the right place then the message box won't appear and the registry key will not be added.

I think that the system remembers that at some point in the downloading process, there were no calibration data and suggested that you contact LeCroy service for this.
That's right, once it gets tripped it doesn't go away unless you tell it to never come back, but then it will never ever be displayed even if your cal data does go missing, which is why I recommend deleting the key altogether.

Got my hands on a later vintage 7300A (2006) with a bunch of software options and XL memory, so I'm working on making sure it's in good shape.  I've run into a couple of strange problems I've yet to figure out, and while I expect to be checking the acquisition board next for loose connections (it's an odd behavior and the feet were damaged in transit), I'm wondering if anyone's run into either issue.

First, the small one, since upgrading to the latest xstream software, the front panel lights are losing it a little.... They will show normally, but intermittently update to show things off which shouldn't otherwise be.  It doesn't actually effect acquisition or settings, but I'll have channel lights changing every few seconds in some cases even when all four are acquiring normally.  All the buttons work fine, and it seems that pressing a button that makes it update the lights makes the right ones come on.

The second issue is the bigger one: it acquires properly and the inputs seem to be in fine shape, but on every retrigger, I can hear a relay click, which is then followed by some "processing" time in the lower right status indicator and a retrigger point of close to two seconds later in auto mode, even at very short time scales.  The front panel is largely unresponsive when it's doing this, and it happened on the 6.x version of the xstream software it shipped with.  I almost wonder if it's some holdoff setting for sending the screen info out to the network or something... but the remote control options are disabled, and I've been unable to get it to retrigger any faster or without the relay click.  Aside from this obvious deficiency, I can trigger off of whatever channel, I can change ranges and time scales normally, I can read a signal, it passes all self calibrations, etc.



Compared to the 2001ish 7200 I've worked with, it's relatively similar inside in the top compartment, but the motherboard is newer, an Intel D865GLC, so it supports up to 3.4GHz socket 478 chips with hyperthreading and dual channel DDR400 memory (4 DIMMs) - whereas I think the 7200 non-A used an 815 based board that didn't support the later socket 478s or hyperthreading.  Also runs Windows XP instead of 2000, so it can use much more modern xstream software.  Had some strange response issues initially with the clicky knobs on the front panel (most of them), but it seemed to be corrosion or something because just in using them a lot they've cleared up.

What options are installed?

I don't know about your LED problem but you might want to reset to default settings and see if it cures your triggering (perhaps somebody left it doing a lot of post-processing or protocol decode on every capture).

File->Recall Setup, towards the bottom-right is button for "Recall Default Setup"

XMATH, JTA2, a couple other things - a nice little set!

Resetting defaults was the first thing I tried, no dice, at least in 8.1.2.

Checked connections on the top, checked around a bit in the software, then popped open the bottom and checked the acquisition board.  Didn't power it up when open (couldn't be bothered at the moment to get the big fan), but none of the connections were loose, cleaned out some dust, popped a couple of front end shield cans and didn't really see anything amiss with the relays, but no results.  So I went and uninstalled all the software that wasn't windows stuff, ran RegCleaner, and reinstalled the newest xstream software.... same issue.

Also scoped the gigabit ethernet connections from the PCI card down to the acquisition board, and at the very least everything is alive.  The only error I could find in the logs was an I2C error of some description, but it doesn't show up in the UI at all and doesn't really elaborate as to what it is.


I'm thinking I may want to check the PCI interface board next, and maybe swap it temporarily for the one in my 7200.  I believe there's some options/configuration memory onboard, but it should still at least function on a basic level using the other card - and if something acts more normal, then I've got a good starting point.  I have some ProBus probes so I need to remember to try them too, just see if all the connectivity near the front actually works.

hi all. interesting discussion and achievement. i've acquired a lecroy sda scope born June 2003 with Intel D845GRG motherboard in it. it seems the cpu and memory already maxed out. so i'm thinking upgrading the motherboard, so a compatible 3GHz+ Pentium D is in my eye now but... the original P4 2.53GHz is 60W cpu. the one i'm looking is 130W dual core. my concern will be the extra load that sda scope's PSU will have to take. i'm afraid the PSU will be short life, what do you think guy? is it or it isnt? anyone of you upgraded to 100W or more wattage cpu? and used it at extended period of time?

I'd just pick an upgraded board that supports a chip with a better TDP - if I remember right, Pentium Ds were based off of Prescott P4 cores essentially, which were less efficient per watt than the earlier P4 Northwoods.  Going with a specifically low power chip could help, but going to something a little newer (core duo or core 2 duo) should get you back in the right TDP ballpark.  I'd think over 100W is risking it (though maybe not too much), but I think 80W ballpark chips would be fine.  Haven't looked on the specific power supply specs, but odds are good that it's a better supply than equivalently rated commercial parts, and it's probably somewhat over-rated for the requirement.

i'll use lower speed pentium D 945 @ 3.4GHz , 95W think should be ok, 0.2GHz wont gain much for the power wasted. ordering parts is in progress, the worst case is i think, i have another (obsolete) PC for the kids to play king kong pong :P

I've looked some more into my relay-click-and-processing-delay-on-every-acquisition issue and I think it's pointing more and more towards software, but I'm not certain how to go about fixing it yet.

I suspected the PCI interface card because the processing delay and front panel lights flashing could have been linked to issues there, but swapping for a known-good one in a WP7200 yielded the same results.  I dove into the user manual to try to find things that could do it, so i suspected it getting stuck in sequence mode, and it wasn't, though the delay in loading is somewhat similar in some cases - just without the relay click.  I also found that when set to roll mode the relay doesn't click and the scope behaves exactly as the working WP7200.  Then I went through some variables in the X-Stream browser, and I found that in the root of the acquisition top level folder is a CalNeeded variable, which on the unit with the issue is set to 15 whereas the working WP7200 has it set to 0.  I tried setting the value to zero, but it doesn't seem to allow editing it, though some others can be changed.

Since the self calibration also involves relay clocking and a second or two, I suspect this setting is forcing a recalibration with every new acquisition, and maybe this instrument was part of an automated system that required that in its former life... but I haven't yet found how to change this value.  I don't see any error messages or reports in the packaged diagnostic logs that indicate missing calibration data.  The automation manual mentions it and shows VB script that can change it (or at least read it?), but I'm hoping there's another edit I can make or LXI command I can give to set it to see if it fixes the issue.

my SDA (based on WM8K i think) do this calibration-processing when i change vertical V/div scale (each time change iirc even when i get back to previous scale) and on few timescale changes a click, but when i stick to the same vertical and horizontal scale setting, calibration wont click again. i guess this is how it works? i read comments of free_electron on how annoying it is to him, he even complained this to lecroy to no effect. there's menu in utilities iirc to disable this calibration process, if i disable it, i got fewer clicks but it still clicks sometime. according to manual/text, it will click when there is temperature changes, so maybe this is an issue if we get frequent clicks? not sure. mine is a used one so i dont know how it was when new.

i've made a distant order for a used D865GSA board (with unknown CPU intact and its backpanel shield which is different from original board) at a cost of new modern MoBo :-\ mainly because it supports not only P4 and Celeron (my not favourite name) D but also PD and it got LGA775 socket so its newer so it should be better? also most importantly i want to limit the option to MoBo that only support DVO to AGP output, that means an old MoBo, as outlined by my master (the now banned too bad!) Weuscthund (if i spell it incorrectly), so i can reuse the Lecroy AGP card in its original way, i dont need built in LCD upgrade so far, the existing one is fine (except a green vertical line on the rightmost part of the screen) and 800 x 600 is less burden to Gfx/Gpu processing i think so it should increase performance?. if i want super resolution i will use back VGA port and a PS/2 mouse.

i think (to the limited power of my search and keywords) D865GSA is the last and latest version that support DVO out. i will couple it with PD 945 3.4GHz, 2x2MB L2 cache 800MHz FSB, its only 95W. i see some supplies still available used from our local sellers. some P4 HT are rated 100+W as well, the lower wattage one only limited to none HT CPU, even if they have, HT still not a true dual core and maxed out to 2MB (instead of 2x2MB) cache. i hope you are right about the PSU is robustly designed and i hope it can take the extra 30W happily. i will also need to buy 2 x 1GB DDR400 ram, there are also still supplies for that locally. and SSD of course! i hope Dxl driver will work in it and Win7. finger cross..

And why do not you want to use a newer and more advanced platform just like other users did (http://www.eevblog.com/forum/testgear/upgrading-mainboard-in-lecroy-dda-3000-(aka-wavepro-7300a)/msg1146067/#msg1146067)?  Why dig up mummies from the museum?

By the way, no one can sell me the front panel for WP7K (P/N 70F1XXX14)? I am happy to buy even the old one and the broken one (for restoration), because I don’t have any at all  :-//

From what I've seen, they're very likely to be damaged, so many are missing or are in pieces.  Have you tried asking LeCroy for any stock?  There are a lot of scopes in this form factor that should use similar bezels, so salvaging one from another may fit, but they seem to be very commonly missing or damaged.

I considered asking LeCroy for a mechanical drawing so I could look into 3d printing one, since my WP7200 is missing it entirely, but never ended up following through (too many other things going on - the usual).

I contacted LeCroy, and so did other people, but no one was successful in buying this front frame. I have the hope that someone was more successful and now he is ready to sell me his broken frame. This problem has not been solved for me for several years. Therefore, if someone has such an opportunity, I will be grateful for the personal message.
I know that this frame is also compatible from the LeCroy LС-series, as well as WP 9xx.
