content: Hello hello, I am very new to the EEVblog and so please pardon any mistakes.Background history about the device:The place I work for had a broken Oscillscope, a LeCroy Wavesurfer 24Xs. They wanted to get it fixed, but the place they went to wanted about 3000$ for the repair. I as an apprentice there got the chance to take a look at it because it was to expensive to get repaired. My chef told to look for any burned things, which I couldnt see any at the time. After nothing has been found, they decided to throw it away. When they said so I asked them if I could take it home and try my luck there. They very kindly said yes. At home I assembled everything together to see what the current situation is and when i hit the power switch it just worked.What the actuall question is about:Now that I got a working Scope, I was wondering what upgrade I could do to it.One thing I was thinking about was changing the fans. The Scope gets really really hot, even so hot that touching the BNC conecctor on front is pretty painfull. Is this a good idea? or does the device need this high temperature to stay stable?The other thing is upgrading the HDD to an SSD. The HDD is connected via I think so called IDE connection, I was think to get some adapters and load the contents of the HDD to the SSD and use again a adapter that converts SATA to IDE. Would I benefit from the speed of the SSD with those adapters? Is that a good Idea?And the last thing is, does anybody know of some kind of uphack or software options which i can unlock for this type of lecroy or where I could get some infos about it? The thing about this scope is, that I cant analyze any kind of protocolls with it.I got some pictures from inside of the Scope, I will post some. If anyone needs more detailed ones I can send those too.Thank you very much.

content: Hello SelectLOLTo answer your first question, it's not normal for an oscilloscope to heat up as much... For your information, the BNC connectors of my WS434 remain at room temperature even after 4 hours of use. There must be a problem on your acquisition card.Otherwise, it is entirely possible to replace the original disk with an IDE SSD. I replaced the original Fujitsu MHT2030AT drive with a KingSpec 64GB PATA / IDE so without having to go through an adapter. It works very well and I save 50" on each boot up.For the last question I unfortunately cannot help you.Sincerely

content: To the OP:I'd start with checking a few things:- Do all the channels still work?- Do all the BNCs get equally hot?- Are all the fans running?By the looks of it this oscilloscope has front-end amplifiers in metal cans next to the BNCs. My assumption would be that the problem is somewhere in there if the BNCs get hot. You forgot to take a picture of the most interesting part: the board where the BNCs are on (top and bottom).
