NOTE: A Square-Wave Signal Modulates The External Sweeping

Input to Produce 1Hz and 1MHz, showing the 1,000,000/1 frequency

range of the function generator.

NOTE: The bottom trace is the sweeping signal and the top trace is

the actual generator output. The center trace displays the 1MHz signal

via delayed oscilloscope triggering of the upper swept output signal.
