There are eight range switches that select output frequencies from <1 Hz to 10 MHz. The coarse frequency knob adjusts the frequency within a range from 10% of the maximum to the maximum. For example, if the 100 kHz range is selected, the output frequency can be adjusted from 10 kHz to 100 kHz. The duty cycle, CMOS level, DC offset, and -20 dB functions are only active if their corresponding switches are pressed in. The duty cycle knob alters the symmetry of the waveform through skewing or changing the ratio of “on” time versus “off” time. The DC offset changes the mean amplitude of the waveform. Reference the manual for information on more advanced capabilities such as the sweep functions, TTL/CMOS, and voltage-controlled generation.

The best way to “see” the output of a function generator is to use an oscilloscope. An oscilloscope will show you a graphical representation of the signal, and allow you to understand the effects of the waveform shape, frequency range switches, coarse/fine adjustment, duty cycle, DC offset, etc.

A signal generator is designed as a precision device that can produce very specific waveforms; it is not designed as a powering device capable of generating large voltages or currents from its output. This is one of the reasons why a signal generator is commonly used alongside a DC power supply. A common benchtop DC power supply excels at providing a precise DC voltage at a moderate current (usually less than 10 A), but it cannot produce waveforms on its own. If you want to produce a waveform with moderate voltage/current, one great method is to design an amplifier circuit. An amplifier circuit commonly uses a transistor (or series of transistors) to turn small low-power signals into larger moderate-power signals. The signal generator provides the small signal to the input of the transistor, which modulates the DC voltage at the output of the transistor to create a larger moderate-power signal. This is the type of circuit you will be testing to complete this certification.
