To Connect Protection Adapter - Keysight Technologies B1505A Configuration Manual

To Connect Protection Adapter

Keysight N1261A protection adapter is used to protect GNDU or HP/MPSMU module
from high voltage. The N1261A should be installed near your DUT interface as shown in
Table 5-1 on page
The N1261A-001 is also used for the measurement using the N1265A test fixture. It must
be connected between the HP/MPSMU and the N1265A SMU input. Then use four
16494A triaxial cables for Kelvin connection or two 16494A cables for non-Kelvin
connection. Recommended cable length is 1.5 m. Ignore
N1261A-001: HPSMU protection adapter, Triaxial(f)-Triaxial(f)
N1261A-002: GNDU protection adapter, Triaxial(f)-BNC(f)
N1261A-003: HPSMU protection adapter, Triaxial(f)-HV(jack)
N1261A-004: GNDU protection adapter, Triaxial(f)-SHV(jack)

For the Kelvin connection, prepare additional one more cable and
connect it between the Sense connectors. Or use 16493K Kelvin
triaxial cable instead of 16494A.

NOTE
For connecting HP/MPSMU, use either 16494A or 16493K. But the 16493K cannot be
used for connecting the N1265A.
