To Connect Ultra High Current Expander
To Connect Ultra High Current Expander
The ultra high current expander is built into the N1265A test fixture, and is used to
configure the ultra high current unit (UHCU) with the MCSMU modules. The UHCU
output can be applied from the Selector Output terminals of the N1265A, and extended by
using the N1254A-524 Prober System Cable, 1.8 m. See
"Selector Output Terminals" on
page 3-13 for the selector itself and the output terminals.
The N1254A-524 system cable is used to extend the Selector Output and Gate terminals of
the N1265A, and can be connected to these terminals directly. See
"Connecting System
Cable to N1265A" on page 5-37 .
The other side, prober side, of the system cable is a connector box which provides the five
connectors for connecting cables from manipulators. The connector box should be installed
near your DUT interface. See
Figure 5-18 for the connection image.
The prober side connector type, maximum voltage, and maximum current of the
N1254A-524 are shown in
Table 5-28 . See Table 5-29 for the output connection cables.
CAUTION
Do not grab the fixture cover when lifting the N1265A.
Do not apply voltage/current over the maximum limit of the cable. See Table 5-28 .
