Connecting the 16493G Digital I/O Connection Cable
If multiple accessories are used, the accessories must be connected together by using the
Digital I/O cable. Then the cables must be connected from the B1505A to the accessories
in the following sequence.
N1265A Ultra High Current Expander / Fixture, if used
N1266A HVSMU Current Expander, if used
N1268A Ultra High Current Expander, N1258A Module Selector, or N1259A test fixture
NOTE
Using Universal R-box
The universal R-box is a blank box, kind of a do-it-yourself kit for installing a resistor you
want.
You need to prepare the hexlobe (torx type) screwdriver T-10 to remove the cover.
After installing a resistor, reattach the cover. Do not use the universal R-box under the
condition that the cover is removed.
NOTE Connecting or disconnecting the N1254A-524 Prober System Cable
The prober system cable is used to extend the UHCU (ultra high current unit) output to a
probe station.
You need to prepare the box wrench (M5 hex) to connect or disconnect the system cable.
If the system cable is used, the 16493J interlock cable from the B1505A or the N1268A
must be connected to the interlock circuit installed in the shielding box of the probe station.
Do not connect the interlock cable to the N1265A.
