Getting Started in IC-CAP

These procedures assume the following:

    • The system has been set up and switched on according to the instructions under:
     • Agilent 8510-based system—Configuring the System Hardware in Appendix B, "Using IC-CAP with an Agilent 85122A Precision Modeling System."
     • Agilent 8753-based system—Configuring the System Hardware in Appendix C, "Using IC-CAP with an Agilent 85123A Device Modeling System."
     • Wiltron 360-based system—Refer to your Wiltron documentation
    • The calibration standards have been removed from their containers to allow them to reach ambient room temperature.
    • The IC-CAP software has been properly installed on the computer.
    • IC-CAP has been configured to recognize the system hardware, and the SMUs have been renamed as follows, based on the instructions in the appropriate chapter:
     • Performing Hardware Setup in IC-CAP in Appendix B, "Using IC-CAP with an Agilent 85122A Precision Modeling System"
     • Performing Hardware Setup in IC-CAP in Appendix C, "Using IC-CAP with an Agilent 85123A Device Modeling System"
Rename a medium-power SMU connected to the device base as SMU1

Rename a high-power SMU connected to the device collector as SMU2

Rename the GNDU unit (which must be connected to the emitter) as GND.

Refer to Appendix A, "Agilent 85190A IC-CAP" for instructions on opening the IC-CAP software and accessing the model file you need. Find the high-frequency BJT model file under:

/examples/model_files/bjt/bjt_ncehf.mdl

Then return to this chapter and continue with the procedures here.

Before you continue, create a new directory (using the mkdir command), to store the data and model files that will be generated, and then change to that directory.
