GW Instek Direct Digital Synthesis (DDS) Function Generators
3 MHz DDS FUNCTION GENERATOR
SFG-1000 Series, an economic function generator with high accuracy and high stability output, is
designed based on the DDS (Direct Digital Synthesized) technology embedded in a large scale FPGA.
The frequency range of 3MHz and the output waveform selection of Sine, Square, Triangle and TTL of
SFG-1000 Series adequately provide the fundamental features to ensure high confidence for the test
results. The DDS technology at an affordable price gives a high value solution to the users who need a
signal source for accurate but unsophisticated measurement applications.
