Please suggest a really cheap SPDIF coaxial BNC cable for testing if my DAC is working


I am in the process of finding out whether my Transport is not sending signal or DAC is not receiving because my DAC displays "No Data" error. Changed ll cables, inputs, no change. I now found an old Wadia 1000 DAC which uses only SPDIF coaxial BNC cables. When I searched on Amazon, while I found BNC cables, they were not SPDIF. I do not want to get the wrong ones. Can someone help me find really cheap SPDIF cables with BNC termination Male-Male? These are only for testing and if the equipment works, I will get better cables but for now, I want to get some $20 or so cables, if possible.  I would appreciate if you can give me a link to the right ones. Thanks

Parts Express has a sale, with all kinds of that stuff. Very reasonable.

You look up the right cables, geez.. then you’re the one to blame for the goof up.. :-) No, I’m not gonna pay for it to. Well maybe, ask nice.. :-)

Free shipping over 49.00 Ithink..

The Beldon 1694A from Blue Jean Cable.  BNC/BNC terminations at 6 feet for $21.50 plus about $8 shipping.  This cable is actually quite good and I found that I liked it better than some other more expensive cables (in the $50-150 range).

You can have it terminated with other combinations as well if you wanted, such as RCA/BNC.
alternatively, you could get some RCA-to-BNC adapters from Monoprice.  They are basically $1.33 each, plus shipping.
The cables don’t have to be labeled SPDIF. Any 75-ohm coaxial cable assemblies with the right connectors will be fine. The last time I looked, the least expensive ones were labeled as master clock cables. For example, this one!

Just don’t tell your audiophile friends you paid only $7.95 for it.

P.S. You say you might be getting "better cables" if the gear is working. I’d advise you to try this one for a long time before spending your money on boutique digital cables. You might even want to pick up some Techflex and put it over, to look more expensive. This one meets the specs and should be perfect.
Blue Jeans are reasonably priced and have never had any cable of theirs fail. Can't say that about some cables I've bought from "hi end" cable companies. One digital cable was DOA (a VOM meter confirmed no continuity) and an XLR cable's termination fell apart. 
just try an interconnect to see if the sig\aanl is coming through
He needs BNC connectors on the cable, so interconnect won't work.
