## Overview

The GW Instek SFG-1003 is a compact, economic DDS function generator featuring a 0.1Hz to 3MHz frequency range with ±20ppm accuracy and stability. Powered by FPGA technology, it offers selectable sine, square, triangle, and TTL waveforms displayed on a crisp 6-digit LED screen. Designed for professional testing environments, it includes UK and EU plugs for global compatibility and delivers precise, stable signals ideal for accurate measurement applications.

## Description

The SFG-1000 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 SFG-1000 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.

Review: Good value - This is excellent value and works really well. It has both push button frequency selection and a dial sweep so you can sweep a range of frequencies to get a plot on the scope of frequency response (which normally requires a ramp function). The best I could find with a fair bit of research.
Review: Good for accuracy on frequency - Setting up each time takes getting used to

## Questions & Answers

**Q: What's the max peak-to-peak voltage?**
A: Hi Jerry, it's 10Vp-p (into 50 Ohm load).  plus/minus 20% at max. position.  Below is the datasheet for your review.http://www.jameco.com/Jameco/Products/ProdDS/2160411.pdf

**Q: Can this work on 240V? as on the back it say 120V, but in the description and in the manual it say 120/110/220/240V?**
A: Back of my unit is labeled "120V". Its possible you can open it up and switch ranges, but its not a full range power supply.

**Q: is the square wave duty cycle adjustable?  if so what is the range?**
A: Yes, the duty cycle of the square wave (default is 50%) can be adjusted from 25% to 75% (See page 23 of the included user guide).

**Q: Does this include hand-electrodes (stainless steel)?**
A: This function generator comes standard with Probe-GTL-101 x 1, and yes, stainless steel.

### ⭐⭐⭐⭐⭐ Good for accuracy on frequency
*by F***. on 17 April 2023*

Setting up each time takes getting used to

### ⭐⭐⭐⭐⭐ Very stable frequency and very easy to set output frequency with buttons or with dial.
*by C***S on 7 July 2014*

Worked well as a function generator. Very stable frequency and very easy to set output frequency with buttons or with dial. Only criticism is that you can't output simultaneously on the TTL and the regular 50 Ohm output unless you are using the square wave mode.
