Contact Us Page 28 | ni.com | PXI Switch Modules Detailed View of PXIe-2593 RF Multiplexer Switch Module Key Features Reconfigurable Topologies As referenced in Table 1, some PXI RF Multiplexer Switch Modules can be reconfigured to achieve multiple topologies within a single device, allowing you to pick the topology that best suits your application. For example, the PXIe-2593 can be reconfigured in software, without any additional hardware, allowing you to reshape the topology into four different multiplexer configurations, with termination options. Figure 5. The PXIe-2593 is one example of a PXI RF Multiplexer Switch Module that can be reconfigured into various multiplexer topologies, ranging from a 16-channel, unterminated RF multiplexer to a 2-bank, 4-channel, terminated RF multiplexer.
