4200A-SCS Parameter Analyzer

4. CV-IV Multi-Switch Module

The C-V/I-V Multi-Switch automatically switches between I-V and C-V measurements. In addition,

C-V measurements can be moved to any output channel without recabling. Each channel is user

configurable for low current measurement capabilities using the 4200-PA preamplifier or standard

current resolution with a SMU Pass Thru 4200A-CVIV-SPT.
