N1265A Connection Guide
Output Connection
UHV Terminals
Output terminals internally connected to the UHV High and Low input connectors on the
rear panel.
High and Low must be connected to the high and low terminals of a DUT respectively. Use
the blank silicon plate and the UHV/SHV to no connector cables (N1254A-520) for
connection.
The ending of cables must be converted for connecting a DUT terminal. You may attach
any adapter or solder a DUT terminal directly. See
page 3-22
For the gate or base terminal of active device measurement using UHVU, use a MCSMU.
Then attach the N1265A-040 protection adapter on the SMU terminals used for the
MCSMU. This adapter is designed for protecting the MCSMU from ultra high voltage.

Figure 3-6 UHV Connection Example
CAUTION
Open the Gate terminals, the Selector Output terminals, and the Bias Tee terminals for the
ultra high voltage measurement using the UHVU.
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.
