Square-Wave Operation

The square- wave function is a unique function for many
applications, such as pulse width modulation (PWM) output,
adjustable voltage control, and synchronous clock (baud rate
generator). You can also use this function to check and
calibrate flow- meter displays, counters, tachometers,
oscilloscopes, frequency converter, frequency transmitter, and
other frequency input devices.
