This Low Frequency Signal Generator is a professional product to generate sine/triangle/square/forward and reverse sawtooth wave. Features: Output Waveform: can output sine wave, square wave, triangle wave, forward sawtooth wave, reverse sawtooth wave, electrocardiogram wave, noise wave. High-speed square wave. Power Supply: DC4~10V. It is recommended to choose DC5V when using the adapter, and 3.7V lithium battery when using battery power. Current: 160mA when the voltage is 5V. DDS Frequency Range: sine wave 1Hz-500kHz (the output amplitude will decrease with the further increase of frequency), other waveforms 1Hz-100kHz (but the upper limit of adjustable frequency is not limited, if the distortion and shaking requirements are not high, use the frequency can be further increased). High-speed frequency (HS) output up to 16MHz, Can choose 1MHZ, 2MHZ, 4MHZ, 8MHZ, 16MHZ. DDS signal amplitude of the offset amount can be adjusted separately by two potentiometers. All setting parameters can be saved, the power will restore the last used configuration automatically. Can section into the value: 1, 10, 100, 1000, 10000Hz. Comes with a power adaptor for power supply. LCD display to indicate the data accurately. Specifications: Plug Type: US / EU / UK (Optional) Material: FR4 + Acrylic Operating Voltage: DC4~10V DDS Frequency Range: 1Hz-500kHz Resolution: 1Hz Sine Wave Distortion:
