* Because all Model 4200-SCS SMUs share a common LO, you only need to connect the LO,SL OUT connector of one Model
2657A-PM-200 to the Model 2657A-LIM-3.
Refer to Model 2657A-PM-200 User's Guide for more information on accessories required to connect
the Model 4200-SCS SMU with the Model 4200-PA preamplifier to the Model 2657A-PM-200.
