Capacitance measurement tests
The 4200A-SCS provides the following user modules to perform C-V tests using the Keysight Models
4284A and 4980A:
• CvSweep4284. C-V sweep test: Performs a capacitance and conductance measurement at each
step of a user-configured linear voltage sweep.
• Cmeas4284. C measurement: Performs a capacitance and conductance measurement at a fixed
bias voltage.
Details on the user modules for the Keysight Models 4284A and 4980A are provided in the
HP4284ulib User Library Reference (on page 6-309
).
If needed, you can initially do an OPEN and SHORT correction on the 4284A or 4980A to achieve
the most accurate C-V measurements. See the Keysight 4284A or 4980A Operation Manual for
details.
