To Connect Ultra High Voltage Expander
The N1268A ultra high voltage expander is used to configure the ultra high voltage unit
(UHVU) with the MCSMU modules. And the UHVU can be connected to prober as shown
in Figure 5-19, by using the N1269A connection adapter. The N1268A should be installed
near the B1505A. And the N1269A should be installed near prober as shown in
"Connection Overview".
