The main output waveform : sine wave and square-wave, triangle wave, sawtooth wave Maximum output amplitude:± 10Vpp (no-load) .Have a filter (can be opened and closed) to suit the output of sine wave and pluse wave. It can be used with oscilloscope to test and debug electronic circuit, the frequency response of audio amplifier and impulse response. The square waveform is suitable for oscilloscope attenuator and the adjustment of probe impulse response. It also can calibrate the sweep time factor of oscilloscope., Weight: 0.220462262 pounds, Manufacturer: FTVOGUE
