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.

Table 2-1		Multiplexer Blocks and Components

	Block 3	holder 3	BIASin3	-	IVin3	IVout3	DIP SW3

Table 2-2		Agilent E5255A Initial Setup

		Block number	IVin cable connection	BIASin/BIASout	Protective resistor

		1	SMU1	BIAS INPUT 51	0 Ω

		2	SMU2	BIAS INPUT 52	0 Ω

		3	SMU3	BIAS INPUT 53	0 Ω

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.
