DDS Functional Signal Generator 0.01Hz To 500kHz Sine Square Triangular Sawtooth Waveform Signal Source Module Item Type: DDS Functional Signal Generator Material: ABS Size: Approx. 140x80x26mm / 5.51x3.15x1.02in Main Technical Parameters: 1. Output Waveforms: Sine waveform, square waveform, triangular waveform, forward sawtooth waveform, reverse sawtooth waveform, electrocardiogram waveform, exponential rise, exponential fall, Sinc pulse, half waveform, full waveform, noise waveform, etc. 15 types waveforms 2. Power Supply: DC4-9V, recommended e DC5V when using the adapter, and 3.7V lithium battery when using battery power(Battery not included) 3. Current: 180MA at 5V 4. Frequency Range: Sine waveform 0.01Hz-500.00kHz (output amplitude decreases with further frequency increase), other waveforms 0.01Hz-100.00kHz (but without limiting the upper limit of adjustable frequency, if distortion and jitter requirements are not high, frequency usage can be further increased) 5. Resolution: 0.01Hz 6. Sine Waveform Distortion: <1% for frequencies below 1kHz, <0.5% for frequencies above 1kHz 7. Output Amplitude: Maximum ±10V (P-P) 8. Output Impedance: 50 ohms 9. DC Offset: Maximum ±10V, with power off function 10. All setting parameters can be saved 11. There is filter that can be turned on and off, which can adapt well to sine and pulse waveform outputs Features: 1. Compact size, full function, easy to operate, portable design. Can be powered by adapter or 3.7V lithium battery. 2. Used in conjunction with an oscilloscope, it can be used for electronic circuit testing and debugging, frequency characteristics and pulse response testing and measurement of audio amplifiers. Due to its excellent accuracy and frequency stability, DDS is also very suitable for oscilloscope scanning time factor calibration. 3. Square waveform output is suitable for adjusting the pulse characteristics of oscilloscope attenuators and probes. 4. There is a filter (which can be turned on and off) to adapt to the output of sine waves and pulse waves. 5. This function signal generator can test various waveforms, such as sine waveform, square waveform, triangular waveform, forward sawtooth waveform, reverse sawtooth waveform, etc. It is specifically designed for professional workers.
