The signal that looks "worse" actually is the transmit signal. It becomes pre-emphasized to compensate for the frequency response of the cable so that it looks nice to the receiver. And yes, I know, this comment may be a bit late. ;)

We had one of these in our lab for some measurements of 10 gigabit ethernet transceivers. For some reason, it never shut itself down properly, so every time we turned it on it said "Windows did not shut down successfully." You have to do start->shut down on the darn thing, you can't just turn it off like a normal scope. Rather annoying. And then one day the power went out in the lab right as I was about to take a measurement. Go figure.

This is true. However, it takes a while to get a measurement set up so you can turn the scope on and let it warm up while doing so. We were using it to take measurements of 10G transceiver lock time through a wavelength selective switch, so we would pick two different transceivers, put one in a test board and one in a computer, clean and connect the fibers, turn on a bunch of optical amps, and configure the WSS before we could even get a trace on the scope.

@AlexForencich 11 жыл бұрын
The pair you're calling 'receive' with overshoot issues is most likely not the receive side but the transmit side. Many high speed transceivers will add pre-cursor and post-cursor pre-emphasis to decrease the effects of dispersion and intersymbol interference. Basically, the idea is to offset the effects of the transmission line beforehand. The other signal is very nicely rounded with no overshoot, showing that the pre-emphasis is doing what it is supposed to.

Not really, there are plenty of applications where, surprisingly, windows is actually perfect for. Personally, I would think that Linux would be a bit shit for a scope but I haven't messed around with many scopes so I don't have enough knowledge about them. In saying that, it would be a massive pain in the ass to make a custom "OS" for it. I guess that's the reason why a lot of the "embedded devices" I see are so slow and shit, they probably outsource it to India where good programming is but a myth told only in small circles and knowledge about the hardware it is being run on is laughable absent. Bloody slow ass terminals with no feedback or any facade of quality programming, McDonalds, Woolworths, and Coles should be ashamed of themselves.

Hopefully the cost of repair does not scale linearly with the cost of the instrument, otherwise expect to pay $7000 to get the OS reinstalled hahahah

***** 10 million is an absolutely tiny number if you put it into the perspective of the year 2015 and an amount of computers which is even bigger than the entire population. Nothing runs on XP anymore - except for obsolete, soon-to-be-replaced systems which nobody cared about up until now (because they're unimportant). Get over it : XP is dead and if you want to have our computer running you need to uninstall OR disconnect it from the internet entirely; its not only danger to itself but also every other vulnerable computer out there. There will always be people who refuse to adapt - and these are always the same people who get left behind. If you want to be "different" simply buy a macintosh - if you want to have something "reliable" use linux - its no problem to keep the same version of linux for DECADES, most of the time. The only OS which "degrades" over time is windows - scriptkiddies keep creating attacks for obsolete software hence users NEED to stay updated, otherwise they soon will suffer the fate of ignorancy.
