Upgrading Mainboard in Lecroy DDA-3000 (aka WavePro 7300a?)
Converter:
1. In fact, there are a lot of motherboards that fit. Any motherboard with 1 PCI port will work. Do not look specifically for the AGP port - you can connect the LCD matrix in any alternative way. I would recommend a motherboard with built-in lvds or parallel (TTL) video output to directly connect your LCD matrix (depending on your matrix model), for example AIMB-582. By the way, this is exactly what LeCroy did in many of his other oscilloscope models. In this case, from the BIOS menu of the motherboard, you will be able to change the video signal format, for example, if in the future you want to use a 1024 × 768 matrix (which you will not get if you use the original video controller).
2. First, check the correctness of all supply voltages on the ACQ board. A large set of different voltages comes from the power supply, and there is also a number of voltage converters directly on this board. You must check each one.

I would love to go for the better screen in the future and even get rid of the AGP card needed so far. For now I need to get this thing working properly and then we go for polish.
Is there any kind of Service-Manual available which gives an overview of the used powerrails on the acquisition board ? Does anyone know where the Monitoring ADC is located and how it comunicates with the Aladdin Card (maybe I2C address)?
I have added some photos of the physical aladdin card, should there be more than the "X-Stream DSO Devices" in the device manager or what is the Hardware-ID of these cards?
What kind of High-Speed-Bus is used by the Aladdin card to communicate to the acquisition board ? Can this bus be tested?
Converter:
I have not yet studied this architecture so deeply. It would also be helpful for me if someone could provide information on the above issues. For communication with the interface board, 6 Gigabit Ethernet lines are used, this is not a secret.

I recently purchased a SDA 3010 second hand and after that i contacted the official Lecroy Support, whether they would be so kind to provide me Performance Verification Documents for this Model. The replied immediately and sent me the following 4 files:
'Chapter 3 - Specificationsrev2.pdf'
'Chapter 4 - Theory of Operation.pdf'
'Chapter 5 - WP7K Performance Verification revD.pdf'
'Chapter 5 - WP7K Performance Verification Test Record revD.pdf'
I won't share this files here on the forum but I want you to know that you can go and ask LeCroy support, they have been really kind and helpful in my case.
Another thing I want to ask if the gerber/schematics for SIL151 hdmi to lvds boards from wldshy are available?

before asking them.... what if our case on Lecroy support is not the same as your case? can we PM?
