N1269A Ultra High Voltage Connection Adapter
The N1269A is used to connect the N1268A UHV expander and the MCSMU
modules to DUT. See Figure 3-26 for connection example. Protection adapters for
MCSMU are initially installed. The N1269A is used with a DUT interface such as
your own test fixture and prober station, not the N1265A.
