- Additional information
DDS Function Generator DIY Kit with LCD includes an already assembled and tested circuit board, a black acrylic enclosure, and two knobs for the potentiometers.
The module has two outputs; one marked “DDS” for the programmable frequency in the range of 1Hz to 65kHz, and the other one marked “HS” for a square wave with selectable frequency of 1, 2, 4 or 8MHz.
Off set and amplitude of the DDS signal can be adjusted using the two potentiometers.
The DDS Function Generator Module with LCD is able to produce:
– sine wave
– square wave
– reverse sawtooth
– triangle wave
Besides these standard waveforms, the DDS Function Generator DIY Kit with LCD can be set to produce an ECG-style waveform (like a heartbeat) and white noise.
The 2-line display shows the name of the waveform and the frequency, the 5 buttons allow for easy settings.
Operating voltage: 6.5 – 10.5V DC, <70mA
Output impedance: <200 Ohms.
We recommend our 9V USB power supply cable (link).
- Connect the power supply to the PCB and adjust the LCD contrast with the small potentiometer (R22) on the backside of the PCB. The factory setting will only show a black screen.
- Assemble and mount the enclosure, then turn the 2 potentiometers to their middle position and push the knobs, with the marker facing 12 o’clock, onto it.
- The up and down buttons change the waveform, left and right adjust the frequency. The center button starts the output and locks the keypad.
- To change settings, stop the output by pressing the center button, adjust the settings, and press the center button again to start the output again.
A disclaimer, because it really happened in the past:
Do not expect to receive a product in the quality of a $20k Rohde & Schwarz device! This is a hobby project and not meant to compete with lab equipment.
