N1260A High Voltage Bias-Tee
High voltage bias-tee is used to perform the high voltage C-V measurement. The
C-V measurement of up to 3000 Vdc can be realized by using the bias-tee,
MFCMU, and HVSMU. The N1260A is used with the N1265A test fixture or a
DUT interface such as your own test fixture and prober station.
NOTE HVSMU is used for the DC bias source. MFCMU built-in DC bias source cannot be
used.
• From HVSMU
HV(jack) connector. For connecting 16493T HVSMU cable from the HVSMU.
• From MFCMU Hcur, Hpot, Lpot, and Lcur
BNC connectors. For connecting N1300A cable from the MFCMU.
• Output Low and High
SHV(jack) connector. Low and High must be extended to the low and high
terminals of a DUT respectively. Use N1254A-518 SHV cable to connect
N1265A test fixture. To connect other DUT interface, use high voltage cable
with SHV(plug) connector, manipulators, and such.
•AC Guard
SHV(jack) connector. Provides the AC guard (circuit common) signal of
MFCMU. For the 3-terminal device measurement, the AC Guard must be
extended to the device terminal which is not connected to Low or High. For
making the connection, use cable with SHV(plug) connector, manipulator, and
such.
To use N1265A test fixture, open this connector.
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.
