The next figures show the basic test configurations for this project:
•
I-V testing : The basic configuration shows four-wire sensing using a 4200-SMU or 4210-SMU.
Four-wire sensing is needed to achieve optimum performance. See Source-Measure Hardware
(on page 3-1) for details on 4200-SMU connections.
•
C-V Testing : See 4210-CVU connections (on page 4-5) for details on connections. Use only the
supplied (red) 100 Ω SMA cables for connections to the 4210-CVU. Be sure that all used SMA
cables are the same length.
After making or changing connections, be sure to use the Confidence Check diagnostic tool and do
connection compensation tests. Refer to
Confidence Check (on page 4-19) and Connection
compensation (on page 4-10) for details.
