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 provide stable operation2. Square wave duty cycle adjustable from 1% to 99%, suitable for adjusting oscilloscope attenuators and probe characteristics3. 15 waveforms including sine, square, triangle, sawtooth, ECG, pulse, and noise, covering common testing and simulation needs4. Built-in switchable filters improve waveform purity in the high-frequency range; parameters are automatically saved, eliminating the need for reconfiguration after a power outage5. Typical applications: electronic circuit debugging and testing, frequency response and impulse response measurements of audio amplifiers, oscilloscope time base calibration, etc.Parameter:Supply Voltage: DC 3.5–9 VOperating 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: Continuously adjustable from 1–99%Sine Wave Distortion: Output Adjustment: Parameters can be adjusted directly during operation without stoppingPower Supply: 5V USB power adapter / 3.7V lithium batteryProduct Dimensions: 140 × 80 × 26 mmPackage include:Host device1BNC cable1USB to 3.5mm audio cable1User manual1
