This Spirent SR5048 Test Configuration Unit is in great condition and was removed from a working environment. This unit came from a large wireless communication manufacturer that was upgrading equipment and was in use prior to removal. We guarantee this unit to be fully functional with a 30 day return policy. We urge customers to view all photos as they show overall condition, included accessories and useful information. Please feel free to contact us with any questions. The combination of the SR5068 and the TAS5048 Test Configuration Units automatically manages the switching of RF connections required for 3G mobile device testing. This allows the C2K-ATS to achieve the highest level of flexibility in test coverage. Combined with the Agilent 3499B Logic/Control System, the TAS5048 can be automatically controlled with TASKIT/C2K software. Reconfiguring the CDMA signaling path in C2K-ATS is automatically handled by TASKIT/C2K.
