Hi,
Did anyone succeed to speed up processing in win XP based Infiniium 9000 scopes? (I already swapped the original Fujitsu 2.5" drive by an SSD after DDing its contents)
Made some search here. Found Intel M370, M385, T7600 but are they electrically compatible?
Furthermore some of them have socket M and P versions available.
After that question is: will BIOS be compatible?
So upgrade seems risky business without authoritative advice...

From the block diagram, USB is used for communication with the scope's acquisition.
Is the current CPU and memory usage close to 100%?
If the bottleneck is not the CPU or memory, but the USB transfer rate, changing the CPU or memory to make it faster will not change anything; it will only make Windows run faster.

This post says that it is PCIe connected. This seems different from what is stated in the block diagram.
Either way, USB or PCIe, it does not make sense to upgrade CPU or memory if the bottleneck is not CPU or memory, but bus speed.

Thanks for your contribution.
Communication between MB and Acq board is done by two SATA cables.
I can't check processor load right now as the scope unfortunately doesn't power up due to one PSU supervisor shut-down and things are currently under investigation. Therefore speeding things up would be the next step. Main concerns are : traces throughput (in waveforms/sec) and render the bandwidth limit processing reasonnably fast enough.
I already saw that MB upgrade thread but seems it's not an easy task... Therefore the expected half-way solution of processor upgrade...

always check you background processes, you could have some who suck resources or not useful at all
i had in an old tds 7254b
xp came with crap in the days

So my 9404A fired up again. I checked XP system processor load. When running the DSO app it jumps from around 10 % to a 96-97 %. So answer is yes. And bandwith limit adds a tremendous amount of interleave between acquisitions.
Therefore it seems that neither SATA nor bus are the culprits as when I revert to 4 GHz bandwidth traces throughput on display is way faster.
