Aideepen | FG-150 DDS Function Signal Generator Frequency Counter 0.1Hz - 500KHz Signal Source Module 15 Waveforms Adjustable Duty Cycle

Features:1. Dual power supply modes: Powered by either a 5V USB power adapter or a 3.7V lithium battery, both of which provide stable operation2. Square wave duty cycle adjustable from 1–99%, suitable for adjusting oscilloscope attenuators and probe characteristics3. 15 waveform types, including sine, square, triangle, sawtooth, ECG, pulse and noise, covering common testing and simulation requirements4. Built-in switchable filter to improve waveform purity in the high-frequency range; parameters are automatically saved, eliminating the need for reconfiguration after a power cut5. Typical applications: electronic circuit debugging and testing, measurement of audio amplifier frequency response and impulse response, and oscilloscope time base calibration, etc.Product Specifications:Supply voltage: DC 3.5–9VOperating current: 150 mAFrequency range:Sine wave: 0.1 Hz–500 kHzOther waveforms: 0.1 Hz–100.00 kHzFrequency resolution: 0.1 HzOutput impedance: 50 ΩOutput amplitude: Max. ±10 V (peak)DC offset: Max. ±10 V (switchable)Waveform types: 15 types including sine, square, triangle, sawtooth, ECG, pulse and noiseSquare wave duty cycle: 1–99%, continuously adjustableSine wave distortion: Output adjustment: Parameters can be adjusted directly whilst the unit is running; no need to stop firstPower supply: 5V USB power adapter / 3.7V lithium batteryProduct dimensions: 140 × 80 × 26 mmPackage contents:Main unit × 1BNC cable × 1USB to 3.5mm audio cable × 1User manual × 1
