Power cable, for connecting to power line
1. HCSMU is substitutable. Then use 16493S HCSMU cable, N1254A-103 adapter for Force, and
N1254A-517 adapter for Sense.
CAUTION
The GNDU can sink current of up to 4.2 A. Use 16493L GNDU cable to connect the
GNDU to the N1267A.
Do not use normal triaxial cable (16494A) because the maximum current rating of the
cable is 1 A.
Table 5-27 To Connect N1266A Output
N1266A
terminals
Low 16493L GNDU cable, N1261A-002 protection adapter and two
BNC(m) coaxial cables (N1254A-503 can be used), or N1261A-004
protection adapter and two SHV(plug) coaxial cables
Protection adapter is not required to connect to the N1258A,
N1259A, N1259A-300, or N1265A.
High HV(plug) triaxial cable (N1254A-505 can be used).
CAUTION
Never connect the HVSMU Force and Guard terminals and the HVMCU High terminal 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.
