Patent ID: 8351863

Claim:
A switching device for the alternate connection of at least one first test port or one second test port to a measuring-device connection, wherein the measuring-device connection provides at least one test-signal input for inputting a test signal, wherein the test-signal input is connected to a signal divider, wherein the signal divider is configured to divide the test signal into a first test signal component and a second test signal component, and a first signal path is configured to route the first test signal component alternately to the first test port for connection to a first device under test or to the second test port for connection to a second device under test with a first switch, and a second signal path is configured to route the second test signal component at least to the respectively other test port, wherein the second test signal component is attenuated in the second signal path and the second test signal component is routed attenuated to the first or to the second test port and the first signal component is routed un-attenuated to the first or to the second test port, and a measurement can be implemented on one of the test ports with the first signal component, and a synchronization can be implemented simultaneously at the other test port with the second signal component.
