Using data collected during the 1992-1993 collider run at Fermilab, CDF has made measurements of correlated b quark cross section where one b is detected from the lepton from semileptonic decay and the second b is detected with secondary vertex techniques. We report on measurements of the cross section as a function of the momentum of the second b and as a function of the azimuthal separation o...
