DDS-Signalgenerator-Modul-Entwicklungsplatine - Outputs two sine waves and two square waves with frequency coverage 0-40 MHz for AD9850 and 0-70 MHz for AD9850. Note: Harmonics rise and waveform quality degrades after 20-30 MHz; square wave output is available up to 1 MHz. - Improved signal-to-noise ratio: Includes a 70 MHz low-pass filter to deliver clearer waveforms and more accurate signal synthesis. - Adjustable amplitude: One pin included for convenient amplitude adjustment of the output waveform. The comparator reference input voltage is generated by a variable resistor, enabling different on/off duty cycles for the square waves. - Stable oscillator design: The AD9850 module uses a 125 MHz active oscillator, while the AD9851 module uses a 30 MHz active oscillator, providing stable and reliable performance. - Compact, reliable DDS development platform suitable for bench testing, signal generation, and RF experiments. Compatible with standard DDS configurations and common test rigs. - Practical use scenarios: - RF signal generation and waveform testing for filters, amplifiers, and mixers. - ADC/DAC calibration and timing/linearization experiments in lab environments. - Education and hands-on practice with DDS synthesis, waveform shaping, and duty-cycle experiments.
