Example 4 - Generating an continuous RF Sweep
Assume you wish to initiate an RF sweep, with the following
characters:
• RF sweeps from 1 GHz to 2 GHz
• Sweeps across 90 points linearly
• Dwells for 20 ms for each point
• Repeats sweep continuously
• Triggers immediately and continuously over all points
