Using Load Cards and Loads 5
E6198B Switch/Load Unit User Manual 5-23
UUT Connections
When configured as part of a standard Agilent system, P2 of the
load card is typically connected via cables to a mass
interconnect panel. User connections to the UUT are then made
from the mass interconnect panel. Refer to the appropriate
mass interconnect wiring guide for connection details.
You can also make connections directly to P2. Figure 5-16 is a
P2 connector pinout showing the details. Each even-numbered
row of P2 represents a single load card channel. The three pins
in each row are connected together on the PC board for current
sharing. When making UUT connections, wire across all three
pins in each even-numbered row. This ensures current sharing
across all pins and prevents premature pin failure from
excessive current flow.
Connecting high-current (>4 amp) loads without wiring across all
three pins in the row can cause premature pin failure.
