Capacitance Measurement

Single Sweep
Double Sweep
Linear Sweep
Up to +/- 25 V, using only CMU
Up to +/- 100 V, using SCUU (Agilent N1301A-100)
C-V Sweep Source
CMU supports the linear single sweep and the linear double sweep. The CMU can sweep up to a
value and then back down (double sweep). This feature is useful when the device must be tested
without abruptly removing the forcing condition.
The CMU can force up to 25 V DC bias. The DC bias can be expanded up to 100 V by using the
SCUU (SMU CMU unify unit) that is used to switch the IV measurement and the CV measurement
automatically. For the SCUU, see the following pages in this module.
