Low-frequency NF generator with the possibility of adjusting the oscillation DS Generator AD9833/328
Just connect the 5V power supply via USB-C and the device will start in the settings as you left it. All settings are made via the touch screen DDS module Signal generator 10-bit Sinewave Squarewave I0H8 equipped with AD9833 chip. The product is a direct digital frequency synthesizer (DDS) with a built-in 10-bit converter, low power consumption and with a 28-bit frequency register. It can realize high-power sine and triangle output and can achieve a resolution of 0.004 Hz when the clock frequency is 1 MHz. Manufacturer Plaza Electronic technology Co. Ltd.
This easy-to-assemble signal generator will generate signals covering a wide range of RF audio. The output frequency can be set precisely and can be used as a sweep generator to test the frequency response of audio circuits, IF filters and more.
Features:
The module is powered by 5V Type-C, the user can choose the desired chip, set the desired spot frequency, sweep start frequency, sweep stop frequency and sweep step frequency. So you set the center frequency and subsequently the frequencies from and to which the device should oscillate spontaneously and a so-called siren will be created... The signal output can be found on the RFqut connector.
With the Point button on the LCD, you start the uniform frequency set via Point Freq.
You can turn off the generator via the Stop button.
If you need a spreadable, retunable frequency, switch it on via Sweep. And the setting itself via Sweep Freq. Start frequency and Stop frequency, that is, in what range the frequency should oscillate and at what speed Step.
You can leave the DDS chip settings in AD9833 for better functionality.
You can set the clock reference frequency and change the waveform output signal. When connecting to an external clock, you must enter the corresponding frequency of the external clock. MCLK input
In Waveform, you can output sine (sine) signal, (square) signal, triangle (triangle) signal.
In the main interface, you can select Point output mode, Sweeping output mode and Stop output mode.
The module supports PC control, and PC control is the same as full-screen touch screen control.
The plug-and-operation is simple and easy to carry, and it can also realize the work of spot frequency and sweep frequency and fully control the touch screen.

The test device of the signal generator module works and up to 3 MHz, if you need a higher frequency, you must purchase a module from DDS AD9850 that runs 0-40 MHz
The AD9833 is a highly integrated device that uses advanced DDS technology coupled with an internal high-speed, high-power D/A converter and comparator to create a complete digitally programmable frequency synthesizer and clock generator function.
Easily generate sine and square outputs up to 3 MHz with this convenient module that interfaces with your development board via the SPI bus. The module is assembled according to the diagram below and ready for use from a 5V power supply.
