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
- sawtooth
- 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) .

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.
