The President "signs" the treaty and then the Senate votes to ratify it. It
does not take effect until it is ratified although the US usually will
follow it.

 The way I read it, the U.S. has signed the treaty, but NOT ratified it. 
What's the distinction?

180 States, the vast majority of the international community, have signed
the CTBT, underscoring their support for a definitive ban on nuclear
testing. 148 of these have also ratified the Treaty. To enter into force,
however, the CTBT must be signed and ratified by 44 specific States. These
States participated in the negotiations of the Treaty in 1996 and possessed
nuclear power or research reactors at the time. Thirty-five of these States
have ratified the Treaty, including the three nuclear weapon States France,
Russian Federation and the United Kingdom. Of the nine remaining States,
China, Egypt, Indonesia, Iran, Israel and the United States have signed the
Treaty, whereas the DPRK, India and Pakistan have not yet signed it.
