Lecroy options -=recovery=-

[mophong]

Thanks, darkstar49.
Since I have read all comments here I have seen someone needed to reprogram eeprom several times.
Anyway, it will be great if someone can confirm -VL and HBW options work for WS 24Xs?

Anyway, it will be great if someone can confirm -VL and HBW options work for WS 24Xs?

regarding the acquisition memory, the name of the option is model-dependent... but I don't think that anything above -L will work on an Xs.
You could also try MMODEL, I think it enables 'maxmem' and -MSURF (and possibly -ATP), not clear to me... but you can proceed one option at a time.

Regarding the bandwidth, I've NEVER seen anybody being successful at modding a LeCroy's bandwidth, excepted for the WS400 series, where the service manual apparently mentions the h/w mod to get to 500MHz (mentioned somewhere in this thread). Bandwidth is limited by the FE, and those are different for each model, so you're unlikely to be successful with the ?BW options. No service manual ever leaked for the Xs/Xi series.

[mophong]

I was asking for -VL option because in the scope's manual they mentioned only 2 memory options, standard (2.5 Mpts) and VL (10 Mpts). But, I will try MMODEL, it is "M model for WR Xi and WS Xs scope" and as I know MXs scope has standard memory of 10 Mpts.
As for HBW option, I actually don't wish to increase the scope bandwidth, just read the comments about DECODE_MEASURE, HBW option may be required to enable DECODE_MEASURE. However I now realize that issue may not the case of WSXs.
Thanks again.

Anyone has list of working options on WaveSurfer 24Xs? Don't dare to desolder eeprom.
Thanks,

I was able to read the EEPROM while it's still on the PCB, using a UART reader described here, so you might not need to desolder it.

Just a note that the python scripts work fine under Linux, no need to deal with Windows

Just a note that the python scripts work fine under Linux, no need to deal with Windows

We had the same discussion last November... Mac OS seemed screwed as well, but I didn't spend 15' on it, jumped into some Linux VM and voilà, it worked...

[tv84]

Let's update the reference to the latest MAUI version.

This is a work in progress, but I think it already provides a good view of all options.

[PaulAm]

I pulled together some information on the options for the DDA-120/LC584 scopes which included links to documentation if I could find it.  Should help to determine what options would be useful in a given situation.  This is a zipped html file.

Nice document. Thank you

btw, there's some documents on groups.io Lecroy group. https://groups.io/g/LeCroyOwnersGroup/. Ex: the 140pages Jitter & Timing
Analysis manual.

[PaulAm]

Yes, that's a much better document.  Thanks for the pointer!

I got a WS MXi-A and want to upgrade

As i have to dismantle the scope i want to Upgrade the fans and the CPU as well
Guess a Intel Celeron M 450 2.0GHz 533MHz SL9KX should work?  (I know its not a big step, but a least 11%) :-)

Any recommendation for replacing the fans?

Are there Manuals around like for the old 4xx series?  :-)

Thanks for all hints

wrong thread somehow...
and do you mean WR MXi-A or WS MXs-A ?

As for the fans, those from LeCroy are pretty OK (at least in the Xi-A/Xs-A/B series), most fans with the same size won't be any better. Just make sure the feet are deployed while using (air is sucked from below), and have a cool workplace... ;-
For the CPU, I'm not with you... any Xs-A/B or Xi-A should support a Core 2 Duo T7600, which is light-years ahead of a Celeron M 450 !!

For the manuals, wrong place, check the LeCroy Owner's group... I think the 4xx SM is available (to be checked , I never had any WS 4xx)

Have fun ! (and open a new thread if you have further questions / topics to discuss around modding your scope)

This is with XStream 8.1.2.0 installed.

Does anyone have a slightly earlier version of the options.cfg file that the python scripts can decode?

Or an updated version of db.py that supports the newer format?

Thanks
David

.....

There is already file with mostly all options listed to download, just read the tread carefully - may choose "all" and search for ".zip" will guide you to: (its a link to an early reply in thsi tread)

Just for future reference.

 There are the most common options listed, so no need to gen the list by your own - and the scripts do not work for options files > 8.x.x.x

[dannich]

Accidently used 03-00000020 RSR Reduced Sample Rate. How can I remove it,
Now my sample rate is limited to 1GS. This is the only key in the list that I can't remove.

[RedCali]

Just for future reference.

same...
- Lecroy-Options-8.1.0.1.txt

has anyone tried to use the options within flag #08? Seems as they are wrongly generated - maybe to "new"....

Example:

Code: [Select]

08-00002000 I2C_TDME 
08-00004000 SPI_TDME 
08-00008000 UART_TDME


result after validation - the flag add the option is "0":

Code: [Select]

Flags: 08
Mask: 0000E000
Options:
00-00002000 USB
00-00004000 SPI_TDME
00-00008000 UART_TDME

in the scope, the key leads in totally different options...
Any ideas / guessing?

[PaulAm]

Does anyone have any info on options for a LeCroy/Catalyst Conquest SBAE30B USB protocol analyzer?

[perdrix]

If you look at https://www.eevblog.com/forum/testgear/lecroy-ws-434-runs-in-demo-mode-as-a-wavestation/

You'll see that I have a WS434 that starts in Demo mode.   I suspect that this may be because the options key that tells the 'scope it is a WaveSurfer has become corrupt.   This key is held in the DS2433 EEPROM on the PCI card:

Section 6.4.1 PCI Board Exchange Procedure says:

   The WaveSurfer uses option keys to identify the correct model number, memory size and software options.
   These option keys must be re-installed if the PCI board is exchanged..

So how can I re-rewrite the option keys in the EEPROM without using XStream to do so?   I'm sure there is a command line way to do it!

Wo ist der Würstchenhund wenn man ihn braucht!

Hi,
I don`t know the demo versions. Can you enter the service menu? Then you could delete all the option keys. But I guess this is not possible.
With more effort involved is the variant of the user sixtimesseven. He explained this on page 3 of this thread. He also attached the necessary code for Arduino and a dump of his eeprom. It's quite simple to change the options keys in the EEPROM. But you have to desolder the IC on the PCI board.
There is no other known option.

Bes regards
Momchilo

[perdrix]

When XStream switches to Demo mode the keys etc. that are presented are AFAIK nothing to do with the real ones.

In any case (as it turns out) the EEPROM wasn't corrupt - see other thread.

Thanks
David

[tv84]

AFAIK, isn't it possible to install the option "00-00000020  DEV" which should allow the removal of other licenses?

[perdrix]

AFAIK, that's not relevant in Demo mode.  The Scope Id and Serial no are unrelated to the real device

David

[tv84]

Isn't DEMO mode just activated by?

01-00002000  DEMOSCOPE

[Momchilo]

But if you look in the other thread, there are only 2 keys stored in the eeprom.
