Input:
I wanted to have a complete set of test probes and T-connection to use for my class because parts provided by school are old and not reliable.  As it turns out, I think I would have been better off using those parts than this piece of junk.  I wasted most of my time trying to figure out my output was noisy or not present at all.  I went over my circuit carefully and everything was connected correctly.  I tried using different wave generators and oscilloscopes, but nothing worked.  I finally borrowed a T-connector and all my problems went away.  This thing is so cheaply built that if you pull on the BNC connector just a little bit, it comes apart.  Don't waste your money.
