Table 3-5 N1265A Status Indicator and Selector Connection Path
CAUTION Never connect the UHVU 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.
CAUTION For the ultra high voltage measurement of active device, connect the UHVU High
terminal to the drain/collector terminal of a DUT. And for connecting the gate/base
terminal and the chuck terminal, use two SMU output terminals which are
connected to MCSMU and are attaching the N1265A-040 protection adapter. Then
connect a High terminal to the gate/base terminal, and the another High terminal to
the chuck terminal. And connect all three Low terminals to the source/emitter
terminal.
For the other cases, never connect any other measurement resource to the UHVU
Low terminal or the DUT terminal connected to it. Connecting other measurement
resource may damage the connected one.
