PXI-2597 Topology

This figure describes the topology of the module.

Module software name: 2597/6x1 Terminated Mux (NISWITCH_TOPOLOGY_2597_6X1_TERMINATED_MUX)

Caution The terminators on the module are rated for 1 W average power at 25 °C, with power on all terminators not to exceed 3 W. Terminators cannot withstand the full rated power of the module.

Making a Connection

In this topology, you can connect channels by calling the niSwitch Connect Channels VI or the niSwitch_Connect function.

To connect the CHx terminal to the COM terminal, disconnect the previously connected terminal from the COM.

For example, to connect ch1 to com, call niSwitch_Connect (vi, "ch1", "com"). If you now want to connect ch2 to com, first disconnect the existing connection. The sequence of calls for this task is as follows: 

niSwitch_Disconnect (vi, "ch1", "com") 
niSwitch_Connect (vi, "ch2", "com")
Note Any input channel not connected to COM is connected to its associated 50 Ω terminator.
Note All channels are disconnected from COM when the module is in its power on state.

When scanning the module, a typical scan list entry could be ch2->com;. This entry routes the signal connected to ch2 to com.
