Making non-Kelvin connection
As same as the 4155C, the Force terminals can be used to force and measure dc
voltage or current. If you want to simplify the cable connections, open the Sense
terminals and connect the Force terminals only to the test fixture by using the
triaxial cables.
If you make the kelvin connection, use both Force and Sense terminals. Connecting
the Force and Sense lines together at the terminal of the device under test minimizes
the measurement error caused by the residual resistance of the connection cables.
The kelvin connection is effective for the low resistance measurement and the high
current measurement.
Connecting the 41501A/B and the 16442A/B test fixture
Connect the 41501A/B measurement terminals to the 16442A/B input as follows:
41501A/B
Terminals
GNDU GNDU
PGU PGU
MPSMU SMU
HPSMU SMU1 and SMU2
SMU3 and SMU4
SMU5 and SMU6
Use Agilent 16493H GNDU cable to connect the GNDU to a test fixture or a
connector plate. Do not use the triaxial cable. The GNDU cable is rated for up
to 1.6 A, but the maximum current rating of the triaxial cable is 1 A.
There are potentially hazardous voltages of up to ±200 V at the Force, Sense,
and Guard terminals. To prevent electrical shock, do not expose these lines.
Never connect the Guard terminal to any output, including circuit common, chassis
ground, or any other guard terminal. Doing so will damage the SMU.
