*To familiarize yourself with the IC-CAP software, refer to the first three chapters of the Agilent IC-CAP 2004 User’s Guide, model number 85190D.

†To save this hardware configuration: on the IC-CAP main menu bar, choose File > Save As and enter a filename, for example config1.hwd (the file suffix must be .hwd).

‡To save this hardware configuration: on the IC-CAP main menu bar, choose File > Save As and enter a filename, for example config1.hwd (the file suffix must be .hwd).

**S12 is identical to S21 because the attenuator is assumed to be symmetrical.

This completes the functional verification procedure.
