verify the functionality of your amplifier and help
you gain a familiarity with proper operation. At
Out with respect to ground, you should observe
a square wave approximately 30 V in amplitude
with a fixed frequency and duty cycle that varies
from approximately 0 to 100% at a rate of 1 Hz.
The current limit is set to 2 amps.
