Mounting Connectors

To Connect SMU Output

The SMU output connection examples are shown in Table 3-8.

WARNING There are potentially hazardous voltages (± 200 V for HPSMU, and ± 100 V for

MPSMU/HRSMU) present at the Force, Sense, and Guard terminals.

To prevent electrical shock, do not expose these lines.

Before turning the instrument on, connect the Interlock terminal to an

interlock circuit.

Before you touch any connections to these terminals, turn the instrument off,

disconnect the power cable, and discharge any capacitors.

CAUTION Never connect the Guard terminal to any output, including circuit common, chassis

ground, or any other guard terminal. Doing so will damage the SMU.

NOTE

Low-Noise Coaxial Cable

For the extended measurement paths over the connector plate, use low-noise coaxial

cable (Agilent part number 8121-1191). This cable can maximize the guard effects

and minimize the impression of the external noise.

Figure 3-15 shows the cutting example of this cable. Key point is the isolation

between the conductive layer and the center conductor. So, cut and trim the end of

the cable as shown in this figure by using a cutter and so on.
