CVU-3K-KIT
The kit includes one 3000 V bias tee and two 200 V bias tees, cables, connectors, and a
discharge probe. It supports C-V measurements with DC bias at up to three device terminals (one
terminal up to 3000 V and the other up to 200 V)(refer to the CVU-3K-KIT instructions; document
number 071321100).
Figure 23: CVU-3K-KIT
The 3000 V bias tee is designed to work with the Model 2657 high voltage SMU. The 200 V bias tee
is designed to work with the Series 2600 and 4200 SMU instruments. Both bias tees are intended for
use with 4210-CVU as the impedance measurement instrument.
The 4200-PA preamplifier should be removed when the 4200-SCS is connected to the 8010 or to the
CVU-3K-KIT bias tees.
The ground wires must be attached to a known protective earth (safety ground) before
powering-on instruments. Failure to attach the ground wires to a known protective earth
may result in electric shock.
Making measurements through the bias tee
The bias tees include a switch that allows the user to optimize the measurements. For advanced
users, the switch can be controlled by setting an appropriate bias level on the AC inputs.
Complete libraries for a variety of device-specific tests are included in ACS Basic software version 2.1
and later. Use of the libraries is detailed in the PCT User's Manual and the ACS Basic Library
Reference Manual.
Note that the next topics introduce DC measurements for leakage current, and AC and DC
measurements for capacitance measurements. This information is provided for you to better
understand the bias tee modes for tests and measurements that are introduced in the next topics.
You will get a brief overview of how bias tees function and then learn about the three bias tee modes:
