DDS Signal Generator Counter Digital Control Sine Frequency (15MHz ) Features: JDS6600 series function generator can generate multiple waveforms such as sine wave, square wave, triangle wave, pulse wave, and arbitrary wave. The frequency range up to 60MHz, with duty cycle adjustment, sweep frequency, frequency signal frequency and counter function. The output signal, amplitude, and frequency can be displayed simultaneously. The series signal generator has excellent amplitude and frequency characteristics, the appearance of this instrument is exquisite and beautiful. This instrument is widely used in factories, schools, research institutes and laboratories.
