Figure 51: Current pin test
Force test
During the continuity test, SMUs are used in the 2W mode. The test flow is the same as the
instrument card 2W tests.
Sense test
During the short test, SMUs are used in 4W mode. The sense terminal is used to connect the two
SMUs.
During the sense test, the SMUs are used in 4W mode. For high-voltage systems, which use the
Model 7072 HV cards, crossbars on rows of differing types (for example, high voltage rows A and B,
general purpose rows C, D, E or F, and CV rows G and H) should not be used together. Therefore,
the rows used will depend on the SMU ranges (see next Figure).
1. If the current row is A and B:
Use pin 1 to connect the force and sense terminals of the current SMU under test to row A.
Use pin 2 to connect the force and sense terminals of the support SMU (except GNDU) to row B.
Use pin 3 to connect the force and sense terminals of the common lo (GNDU) to row C.
Use the current row (A or B) on the sense card to connect the current SMU under test and the
test support SMU together.

2. If the current row is C, D, E, and F:
Use pin 1 to connect the force and sense terminals of the current SMU to row C.
Use pin 2 to connect the force and sense terminals of the support SMU (except GNDU) with row
D.
