2-67

The following program accepts user inputs for (1) power sweep starting and ending levels, (2) number of
steps in the sweep, and (3) sweep dwell times. After accepting such inputs, the program then commands
the signal generator to obtain a display of the power sweep.

Note:

The signal generator should be connected to a scalar network analyzer.
