To Connect HVSMU Current Expander
The N1266A HVSMU current expander is used to configure the high voltage medium
current unit (HVMCU) by using the HVSMU module and the MCSMU modules as shown
in
Figure 5-17 . The N1266A should be installed near the B1505A.
The N1266A output can be selected from the HVSMU or HVMCU. The switching status is
indicated by the Status indicator mounted on the front panel. See
Table 5-25 for the internal
connection.
NOTE
To switch measurement resource
The configuration of the HVMCU is set by using the HVSMU Current Expander tab screen
of the Configuration window of the EasyEXPERT software. The measurement resource
HVMCU or HVSMU is controlled by each test setup. And the switching status is indicated
by the Status indicator mounted on the front panel. See
Table 5-25 for the indication and
the connection path.
