Lecroy WavePro 950 mini teardown

<< < (4/5) > >>

Ice-Tea:
So, I replaced the rotary with one from a SDA-6020, worked fine... here. I sold the unit and shipped it, now the customer says the rotary is still eratic. And two others as well (that I probably just missed). Does anyone have any experience with those? Any source to get them new? Any other reason why they might be behaving badly?

xemax:
I found this for the encoders:
https://groups.yahoo.com/neo/groups/LeCroy_Owners_Group/files/Encoder Info LT WR1 and WR2/


Another question:
Is the sample memory part of the SDRAM? Or is it separate memory for the options "WavePro M/L/VL/XL"?

It's on the acquisition board, integrated with the ADC module AFAIK.

xemax:
I doesn´t found specs for the HAM631 ADC in the WavePro.

In the service manual of the LTxxx scope i found this:
HAM631 : Hybrid ADC 1 GS/s with 4Mb memory

The HAM631 in the WavePro must have 4 GS/s with unknown memory.

The sample memory options for WavePro 950 are:
    1Ch 2Ch 3-4Ch Standard1M500k250kWavePro M4M2M1MWavePro L16M8M4MWavePro VL32M16M8M
If i activate the WavePro L option do i have more sample memory?

analogRF:
grumpydoc, did you ever try overclocking the cpu? or did you at least find out how to? I would like to do it on my WavePro 960 which i think uses the same cpu board as your 950
