Table 5-23 To Connect N1267A Input
Table 5-24 To Connect N1267A Output
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.
CAUTION Never connect the HVSMU 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.
NOTE Do not connect or put any conductor on the HCSMU Low Force and Low Sense terminals,
outer conductor of the coaxial connectors. Connecting or putting conductor of circuit
common, chassis ground, or any potential on causes the measurement error.
