Abstract Knowledge of basic plasma parameters, such as line integrated density and turbulence spectra, is essential for physics understanding and plasma control. Integration of plasma diagnostic systems into a single port combined with diagnostic cost reduction is an important advance that can impact measurement availability on all fusion devices. This article presents preliminary data from a unique, low cost and reliable millimeter-wave interferometer that has been integrated to operate simultaneously with a collective Thomson scattering system. The interferometer uses only one commercially available frequency chirped source and only one detector. The DIII-D system design will be described together with preliminary design of a tangentially viewing system for the Pegasus spherical torus experiment. {copyright} {ital 1999 American Institute of Physics.}
