CAUTION
High Force and Sense must be connected to the high terminal of a device under
test (DUT).
Low Force and GNDU Force must be connected to the same terminal, and
Low Sense and GNDU Sense must be connected to the same terminal. And they
must be connected to the low terminal of the DUT.
2. HPSMU1 and HPSMU2
Output terminals internally connected to the HPSMU1 and HPSMU2 input
connectors. Force, Sense, and Guard terminals for each 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.
3. HVSMU1
Output terminals internally connected to the HVSMU1 input connector. Force
and Guard terminals for HVSMU/HVMCU High.
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.
Never connect the HVSMU1 Force and Guard terminals to any output, including
circuit common, chassis ground, or any other measurement resource such as SMU.
Connecting other measurement resource may damage the connected one.
4. GNDU1
Output terminals internally connected to the GNDU1 input connector. Force and
Sense terminals for GNDU or HVMCU Low. Force and Sense must be
connected together at the device end.
For using the HCSMU, the GNDU1 Force and Sense terminals and the
HCSMU1 or HCSMU2 Low Force and Sense terminals must be connected
together at the device end.
5. AUX1 and AUX2
Output terminals internally connected to the AUX1 and AUX2 input connectors.
Signal and frame ground terminals for each AUX. Signal must be connected to a
terminal of a DUT.
Frame ground may be connected to the ground terminal of the DUT.
