    The R&S OSP is referred to as "switch unit". Integration ● The base module R&S OSP-B157W8 or R&S OSP-B157W8PLUS is (or must be) integrated in an R&S OSP150 or R&S OSP120 switch unit. ● The extension module R&S OSP-B157WX is (or must be) integrated in an R&S OSP120 switch unit (not in an R&S OSP150).
  • Page 6 DUT input ports of the base module, but bypassed directly to the signal analyzer. Key features of the base module R&S OSP-B157W8 The 6 GHz module R&S OSP-B157W8 with up to 8 channels is based on a printed RF switch board in solid-state relay (SSR) architecture. It allows flexible operation of the connected DUT (up to 8 ports) and measurement instruments.

    Due to normal wear, the SMA and K-type RF connectors of the modules have a limited lifetime of typically 500 connector mating cycles. If these connectors are worn, replace them. For the hard-to-replace DUT ports of the base module R&S OSP-B157W8 or R&S OSP-B157W8PLUS, we recommend that you Use RF connector adapters as port savers.
