The SFG1000 Series, an economic function generator with high accuracy and high stability output, are designed based on the DDS (Direct Digital Synthesized) technology embedded in a large scale FPGA.
The 3MHz frequency range and the output waveform selection of Sine, Square, Triangle and TTL available in the SFG1000 Series adequately provide the fundamental functions to ensure high confidence in 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 simple measurement applications.
