To Configure E5255A
The Agilent E5255A has three 2-input 8-output multiplexers. You can configure
several multiplexers by modifying some internal connections. Component locations
on the E5255A are shown in Figure 2-2, and the relationship of the multiplexer
blocks and the components is shown in Table 2-1. Table 2-2 shows the initial setting
of the E5255A internal connections. The setting does not depend on the slot in
which the module is installed.

To Modify IV Input
IV input connection is defined by the connection of IVin cable and the setting of
DIP switch shown in Figure 2-2. For actual examples of modifications, see
“E5255A Configuration Examples”.
Each DIP switch has four bit switches. Bits 1 to 3 are used to specify which SMU
input connector is connected to the IV input. Bit 4 of DIP switch is used to specify
whether the protective resistors are 0
Ω or not. The DIP switches must be set
properly after you complete the internal connection. Make sure you set the DIP
switches correctly. If not, dangerous voltages may be applied to unexpected output
connectors.
