Table 3-3 SMU Input Connectors and Signals by SMU Type
1. Input
• UHV High and Low connectors
UHV(jack) connector for High and SHV(jack) connector for Low. For
connecting 16493V UHV cable from N1268A UHV expander.
• Bias Tee High and Low connectors
SHV(jack) connectors. For connecting N1254A-518 SHV cables from
N1260A high voltage bias-tee connected to MFCMU.
• SMU 1 to 3 ([1] to [6]) connectors
Triaxial connectors. For connecting HP/MP/MCSMU. The SMU 3 ([5] and
[6]) connectors can be also used to connect HCSMU or DHCSMU (Dual
HCSMU). See Table 3-3.
The connector [1]/[3]/[5] is for connecting Force, and the connector
[2]/[4]/[6] is for connecting Sense of the measurement resource connected to
the connector [1]/[3]/[5] respectively.
For connecting HP/MPSMU, the connector [2]/[4]/[6] can be also used to
connect Force of other SMU if Kelvin connection is not made.
To connect HP/MPSMU, use N1261A-001 protection adapter and 16494A
triaxial cables.
To connect MCSMU, use 16494A triaxial cables.
To connect HCSMU, use 16493S HCSMU cable, N1254A-103 adapter for
Force, and N1254A-517 adapter for Sense.
To connect DHCSMU, use 16493S-021 adapter, 16493S HCSMU cables,
N1254A-103 adapter for Force, and N1254A-517 adapter for Sense.
