Using IC-CAP with an Agilent 85122A Precision Modeling System
This appendix documents procedures for setup, calibration, and control of the Agilent 85122A precision modeling system. Some of these are hardware procedures independent of IC-CAP, and some are hardware control procedures performed inside IC-CAP.
These procedures are common for the various high-frequency IC-CAP models. This is not a sequential set of procedures, but a set of separate hardware-related procedures that are used in conjunction with any of the device modeling procedures documented in the chapters. The procedures in this appendix give detailed instructions for the following:
| • | Configuring the system hardware |
| • | Performing hardware setup in IC-CAP |
| • | Calibrating the network analyzer |
| • | Defining the instrument states in IC-CAP (for DC, capacitance, and S-parameter measurements) |
In some cases, you may not need to perform all these procedures each time you model a device. The system setup procedures are performed rarely. On the other hand, the network analyzer calibration must be performed regularly. Setting the instrument states is done for each measurement setup in each model, and the settings can be stored.
