Transfer Switches

An RF transfer switch (DPDT) has four ports (1–4) and two states (reset and set). In the reset state, port 1 is connected to port 2 and port 3 is connected to port 4. In the set state, port 1 is connected to port 3 and port 2 is connected port 4.

Using a Transfer Switch

The following figures illustrate example uses of a transfer switch.

  • Testing two DUTs with different instruments

  • Testing antennas

  • Testing multiple filters with the NI PXI-2596
