Kelvin Connections
To make force-sense connection at PC I/F input
To keep the Kelvin connection up to the Agilent B2220A probe card interface (PC I/F)
input, not output, see
Table 5-3 instead of Table 5-2.
Connect the adapter to the PC I/F input, then connect the GNDU cable between the GNDU
and the adapter. The path over the PC I/F input will be the non-Kelvin connection.
Table 5-3 Required Cables for GNDU Connection (non-Kelvin over PC I/F input)
To pass GNDU output through SWM
If you have to pass the GNDU output through the Agilent B2200 switching matrix (SWM),
use the connection cables listed in
Table 5-4.
Connect the GNDU Kelvin cable between the GNDU and the SWM input. And connect the
Kelvin cable between the SWM output and the PC I/F input. The Kelvin connection can be
supported over the PC I/F output. To make the sense points, see
“Force-sense connections”
on page 5-6.

CAUTION Do not apply high current over the allowable current of the Agilent B2200. The high
current may damage the switch module.
