Combining Bragg and Raman processes allow for manipulation of both internal and external states of atoms in matter-wave interferometry. This enables novel interferometry topologies with the inclusion of techniques such as blow-away pulses, and clock interferometry. In order to investigate the possibilities arising from their combined use, we have realized a system capable of implementing both interrogation techniques, as well as single, double or higher order diffractions in a single setup. Here, we present some preliminary results from the implementation of this system for BEC interferometry.
