Output Connection
NOTE Controlling selector input-to-output path
The configuration and the default I/O path of the selector are set by using the UHC
Expander/Fixture tab screen of the Configuration window of the EasyEXPERT software.
The connection path from the input port to the output port is controlled by each test setup.
And the selector switching status is indicated by the status indicator mounted on the front
panel. See
Figure 3-5 and Table 3-7 for the indication and the connection path.

1. In the normal state, the selector makes the path to the output port from the input port specified by the
Default field. When a measurement is performed, the selector performs automatic switching in every
test. The selector makes the path to the output port from the measurement resource used for the test.
