Source port (#S) external switch control output for noise figure

Output

Indicates that the source signal is out. This signal is changed to the Low level when the source signal is out.

Receiver port (#R) external switch control output for noise figure

Output

Indicates that noise sweep. This signal is changed to the high level when the target port is used in a sweep for noise measurement.

N1966A Pulse I/O Adapter

N1966A can be used for the E5080B. This D connector to RF adapter makes accessing the application I/O signal more convenient.
