The SFG-1000 Series are economic function generators with high accuracy and high stability output and are designed on the DDS (Direct Digital Synthesized) technology embedded in a large scale FPGA. The 3MHz frequency range and the Sine, Square, Triangle and TTL waveform selection adequately provide the fundamental functions to ensure a high confidence with test results. Combining DDS technology at an affordable price, the SFG1003 is great value and the ideal solution if you need a signal source for accurate but simple measurement applications.
