The SFG GW Instek SFG-1013 is an economic function generator with high accuracy and high stability output, that has been 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 GW Instek SFG-1013 adequately provide the fundamental functions required 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.

SFG1013 DDS Synthesized Function Generator

Reviewed by: Howard Chester - 31 August 2014
Pro's;- 1) Ease of use(up and running within 2 minutes of unpacking). 2) Excelent front panel layout including output on/off switch. 3) The TTL output provides a stable reference for LF Phase locked loop(PPL) design experimentation. 4) The ability to select Frequency step changes(eg. Hz, 10Hz, KHz..etc)provides a stable signal for plotting frequency response of Filters etc. 5) Ultra-low distortion, great for Noise measurements of Amplifiers. 6) The Voltage display is a bonus, releasing up at least one of my Digital Multi-Meters 7) The adjustable mark/space ratio of the main Square wave-form is ideal for testing Impulse response of Filters/Amplifiers Con's;- None that are evident over use in the last 2 months. Summing up;- For Profesionals and Hobbists alike. The price, specifications and overall performance ticks all the boxes. On my opinion, a must for any work bench.
