A small compact device that you use to create square waves. Change the frequency of the square wave with potentiometer next to the capacitors and change the duty cycle with the potentiometer next to the red led. You can also change the value of the capacitor with the Yellow jumper pin array, the marking L indicates the highest capacitance of 100uF, the second is 1uF, the third is 0.1uF and the last one with the marking H is 0.001uF or 1nF. Supply voltage to VCC and GND to GND from 5v to 15VDC, the Output pin can go to your device allow with common ground pin GND.

The AFG-2100 Series arbitrary function generator is a DDS (direct digital synthesized) based signal generator designed to accommodate the educational and basic industrial requirements for an accurate and affordable signal Source, 100 MHz Bandwidth covering the output of sine, square (pulse), ramp (triangle), noise and arbitrary waveforms. The 20m sa/s sampling rate, 10 bit vertical resolution and 4K point memory of the AFG-2100 series provide user with a flexible environment for creating the specific waveform output as needed. The 0.1hz resolution of sine, square and triangle waveforms and the 1 percent to 99 percent adjustable duty cycle of square (pulse) waveform are the remarkable features to greatly extend its application range in various fields. Waveform parameter setting through numeric keypad entry and knob selection. Amplitude, DC offset and other key setting information shown on the 3-1/2" LCD screen simultaneously. USB device interface for remote control and waveform editing. AM/FM/FSK modulation, sweep, and frequency counter functions. Measures 266mm width by 107mm height by 293mm depth.
