3-26 Keysight B1505A User’s Guide, Edition 12AccessoriesN1260A High Voltage Bias-TeeHigh voltage bias-tee is used to perform the high voltage C-V measurement. TheC-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 aDUT 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 beused.• From HVSMUHV(jack) connector. For connecting 16493T HVSMU cable from the HVSMU.• From MFCMU Hcur, Hpot, Lpot, and LcurBNC connectors. For connecting N1300A cable from the MFCMU.• Output Low and HighSHV(jack) connector. Low and High must be extended to the low and highterminals of a DUT respectively. Use N1254A-518 SHV cable to connectN1265A test fixture. To connect other DUT interface, use high voltage cablewith SHV(plug) connector, manipulators, and such.• ACGuardSHV(jack) connector. Provides the AC guard (circuit common) signal ofMFCMU. For the 3-terminal device measurement, the AC Guard must beextended to the device terminal which is not connected to Low or High. Formaking the connection, use cable with SHV(plug) connector, manipulator, andsuch.To use N1265A test fixture, open this connector.CAUTION Never connect the HVSMU Force and Guard terminals to any output, includingcircuit common, chassis ground, or any other measurement resource such as SMU.Connecting other measurement resource may damage the connected one.
