1Hz - 500KHz DDS Function Signal Generator

Main features:

Compact in size, fully functional, easy to operate, and easy to carry. It can be powered by an adapter or a lithium battery. Together with an oscilloscope, it can be used for electronic circuit testing and debugging, as well as testing and measuring the frequency characteristics and pulse response of audio amplifiers. Due to the good accuracy and frequency stability of DDS, it is also very suitable for oscilloscope scanning time factor calibration. The square wave output is suitable for adjusting the pulse characteristics of oscilloscope attenuators and probes.

Main technical indicators:

1. Frequency range: Sine wave 1Hz-500kHz

(The frequency with flat output amplitude reaches 200 kHz, and the output amplitude will decrease as the frequency further increases),

Other waveforms range from 1Hz to 20kHz (but the upper limit of adjustable frequency is not limited. If there is no high requirement for distortion and shaking, the frequency can be further increased).

2. Resolution: 1Hz.

3. Output waveform: sine wave, square wave, triangular wave, forward sawtooth wave wave, reverse sawtooth wave wave.

4. Sine wave distortion:<1% below 1kHz,<0.5% above 1kHz.

5. Output amplitude: maximum ± 10V (P-P)

6. Output impedance: 50 ohms.

7. DC offset: maximum ± 10V, related to closing function.

8. There are filters that can be turned on and off, which can adapt well to sinusoidal and pulse waveform output.

8. Power supply: DC3.5-10V. It is recommended to use a DC5V adapter and a 3.7V lithium battery for battery power supply.
