1HZ-500KHZ FG-100 DDS Functional Signal Generator Frequency Meter Signal Source Module Frequency Counter

Frequency range: Sinewave 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 don’t care the phase noise and distortion, it can output full frequency range.
Minimum frequency step: 1Hz
Output waveforms: Sinewave, square wave, triangle, ramp up, and ramp down
Sinewave distortion: 1% (frequency <1kHz); 0.5% (frequency >=1kHz)
Maximum output amplitude: /-10V
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. A 5V AC/DC adaptor or a 3.7 Lithium battery is recommended.
