Item Type: Function Generator Material: ABS Color: As shown in the picture Frequency Range: Sine wave 1Hz~500kHz (Magnitude is flat up to 200kHz, above 200kHz, the magnitude may drop as frequency increases), other waveforms 1Hz-20kHz with good phase noise and small distortion, if you dont care the phase noise and distortion, it can output full frequency range. Resolution: 1Hz Output Waveforms: Sine wave, square wave, triangular wave, forward sawtooth wave, reverse sawtooth wave. Sinewave Distortion: 1% (frequency =1kHz) Output Amplitude: Maximum 10V(P-P). Output Impedance: 50 ohm DC Offset: Maximum 10V, can be disabled Internal Filter: For sinewave or pulse, can be turn on/off Power Supply: DC3.5-10V. DC 5V adaptor or 3.7V Lithium battery is recommended. Weight: Approx.172g/6.1oz Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
