Introduction
The SMU/Pulse Generator Selector provides the built-in switching capability to select a measurement
path to the Output port. The Input ports should be connected to the measurement resources, a SMU
and a SPGU channel. And the Output port should be connected to the DUT interface.
There are two Output ports on one selector. In this example, SMU6 and PG1 are connected to the
CH1 Input ports of the selector #1, and SMU7 and PG2 are connected to the CH2 Input ports. For
the SMU connection, connect the Force terminal only. The Sense terminal must be opened.
Two 16440As can be used. Connect the dedicated control cable between the CONTROL Output
connector of the first selector and the CONTROL Input connector of the second selector.
Switching can be controlled by the B1500A/EasyEXPERT via the 16445A selector adapter. And the
switching status is known by the status indicator. When the SMU indicator lights up, the SMU Input
to Output path is made. And when the PGU indicator lights up, the PGU Input to Output path is
made. If the PGU Semicon indicator goes off, the PGU path is opened by the semiconductor relay.
This feature is only for the CH1.
