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
near the B1505A. And the N1269A should be installed near prober as shown in
"Connection
Figure 5-19 To Configure UHVU
WARNING
Connect a wire from an electrical ground (safety ground) to the earth terminal of the
N1268A.
