GW Instek SFG DDS Sine Wave & Triangle Wave
The SFG-2000/2100 Series generates signals by continuously
delivering a series of sampling values from a sine waveform
table (stored in RAM) to DAC (Digital to Analog Converter)
for waveform construction. With a low pass filter circuit to
filter out the harmonics of the DAC output and smooth the
signal, the SFG-2000/2100 Series is able to provide a stable
output with very low waveform distortion. This is very different
from the way a conventional FG generates a signal. Since a
Conventional Function Generator Sine Wave & Triangle Wave
conventional FG needs to obtain its signal by switching current
sources between positive and negative directions all the time,
the "Ringing" distortion occurs at the peak of the signal
waveform where the switching is activated. This distortion is
especially serious when the output amplitude is low. For the
SFG-2000/2100 DDS FG, however, the waveform distortion
remains low even when the output amplitude is at only 2mVpp.
