To Connect SMU Output
The SMU output connection examples are shown in Table 3-8.
WARNING Potentially hazardous voltages, up to ± 100 V (MPSMU/HRSMU) or ± 200 V
(HPSMU), are present at the Force, Sense, and Guard terminals.
To prevent electrical shock, do not expose these lines.
Before turning Agilent B1500A on, connect the Interlock terminal to an
interlock cir
cuit.
Before you touch any connections to these terminals, turn Agilent B1500A 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 3-12 shows the cutting example of this cable. Key point is the isolation
between the conductive layer and the center conductor. So, cut and trim t
he end of
the cable as shown in this figure by using a cutter and so on.
