Using pure fiber link would be real nice though, but the stuff you got in mind real looks pricey.
The "Lindy" USB 2.0 MM LWL/Fibre Optic Extender 200m (also the USB 3.0 Version) cost me as an Dealer 340 € exclude Tax. I get an Discount when I buy +3 (327 €).
So search on Lindy.de for:
No. 42702
No. 42707
The good think is the are 100% isolated between both side. Sure the have to use an Power Supply.
The Point for me is I can have the Dongle near the Antenna and the Data can be procecced by the (Virtual) Server in my Basement where its cold and nobdy care about the noise. Thankfully the most Software is that slim and good programmed to run 24/7 over month.
@CopperCone
So does it work in your case (even with the Noisy Power from the Pc)?
@xaxaxa
For me the big Plus is I can connect the SDR with my Server and have a) the best Signal because the SDR is near the Antenna and b) the Signal gets Processed by the Server who runs currently with 20% load. (Behind the Server is an huge UPS and other Stuff).
EDIT: I also will use this USB Card: http://www.ioi.com.tw/products/proddetail.aspx?CatID=106&HostID=2035&ProdID=1060136
Hopefully the work with the ESXi. In need to open the Server and plug them in.
I don't know. I would need to test it, but I did not have a particular test in mind. All I could think to do is maybe hook it up and set some kind of narrow bandwidth with high gain, then jump around the spectrum a bunch to see if any peaks appear. I got the cable but I got side tracked and never touched the PLUTOSDR I have again. The only mod I made is I put a shield tape layer over it because I had some microwave antennas running at the time doing experiments with reflections and stuff and its plastic case annoyed me.
Do you have some kind of algorithm or something (I mean this in general, I can do it manually if its not too crazy) I can use to paint some kind of performance increase metric? Like what settings to use etc.
I also don't know if I should leave it open but shielded (with a SMA cap), 50 ohm terminator, open, shorted or something else. I only have the PLUTOSDR for doing RF spectrum.
Well I do have a digitizier for my HP70000 but its kind of crappy (20MS/S), very well built though. I got very burned out doing the microwave stuff partially because you can't do anything cool without spending a shit load of money, which I did, but I need a shitload more. Also need to finish the house.. I want to install foundation drains/mess with hydrostatic pressure, radon removal, redo underfloor heating, fix the plumbing, add air ducting, redo the electrical, lighting, general finishing, then I can have a proper RF lab down there, it got very cramped where I am also with all the amplifiers and stuff I needed, to the point where working just irritated me. Now I just need $. I am not doing shit unless I get those drains installed because I just cannot tolerate having the god damn foundation leak water around a bunch of super expensive crap. I just wont do put any money or risk into that location until I can do something about it. Also need alot of shop furniture because there is a serious lack of dust control on things like toolboxes etc, with adhock cheap ass shelves, planks of wood, exposed walls being used as shelves, stuff hanging from copper wire, its just not kosher in any regard. I want a few more tool chests, maybe one of those tool chest table things.. all expensive, but I can wheel them out of the way to do floor cleaning and stuff easily. Right now its just a time trap for people that have even mild OCD, best to avoid cleaning it or you will be down there forever.........
Same thing with the attic, I want to transform it into a temperature controlled, insulated sealed attic with HVAC system, then I could have some end of the line equipment up there, related to antennas.. right now you need to avoid nails sticking out of the roof.
