NOTE
Controlling N1258A input-to-output path
The configuration and the default I/O path of the N1258A are set by using the Module
Selector 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 N1258A switching status is indicated by the Status indicator mounted on the front
panel. See

1. In the normal state, the N1258A makes the path to the output port from the input port specified by the
Default field. When a measurement is performed, the N1258A performs automatic switching in every
test. The N1258A makes the path to the output port from the measurement resource used for the test.
2. This condition is when all Input fields HVSMU, HCSMU, and HPSMU are blank.
