DiCon s GP700M Modular Mainframe builds on the enormous flexibility of DiCon s GP700. The GP700M shares the powerful user interface with the traditional GP700. At the same time, it offers the convenience of field installation of fiberoptic switches, variable attenuators, and tunable filters. The instrument can accommodate up to eight modular Plug-Ins and can be configured with non-modular internal components by request. The GP700M Modular Mainframe is available in standard and extended 4U rackmount chassis.
