1. SMU 1 to 3 ([1] to [6]) terminals
Output terminals internally connected to the SMU input connectors on the rear
panel. Force, Sense, and Guard terminals for HP/MPSMU. High Force, Low
Force, High Sense, and Low Sense for HC/MC/DHCSMU. See
For using HP/MPSMU, Force must be connected to a terminal of a DUT. And
Guard must be opened. You may extend it as close as possible to the DUT
terminal for reducing the leakage current of the extension cable. Also, Force and
Sense should be connected together at the device end for making the Kelvin
connection effective for low resistance and high current measurements.
For using HC/MC/DHCSMU, High Force and High Sense must be connected
together at the high terminal of a DUT. And Low Force and Low Sense must be
connected together at the low terminal of the DUT. Also, Selector Output Low
Force and Sense must be connected to the low terminal for connecting GNDU.
For the active device measurement using UHVU, use MCSMU and
N1265A-040 protection adapter for the gate/base terminal and the chuck
terminal. The adapter is required to protect MCSMU from ultra high voltage.
2. Gate High and Low terminals
Output terminals internally connected to the Gate input connectors on the rear
panel. High and Low terminals used for the gate drive.
