Function generators are an integral part of most work that electrical engineers/ technicians do throughout their careers. Some of the best function generators will have high range and yet fine resolution giving the user ultimate control in selecting the desired frequency. We have covered some of the top function generators available in the market today based on a number of channels, types of waveform, range and cost.
10. SainSmart FG-100(35.99$)
An affordable function generator for all those hobbyists out there. It has a range of 1Hz to 500kHz. You can generate a maximum of 10Vpp output waveforms over three different types; sine, square and triangle.
9. Hantek DSO4072C(299.82$)
An Oscilloscope with a combined function generator. You can output waves up to 25Mhz of three types; sine, triangular and square.
8. Xminilab Portable Oscilloscope and Function Generator(140$)
Portable Oscilloscope and Function generators weigh 14.4 ounces and is great for students. Though it has its limitations, it can still generate Sine and square waveforms up to 50Khz.
7. 5MHz Arbitrary Waveform Dual Channel DDS (97$)
The function generator can generate waveforms at 5Mhz frequency and has multiple types such as sine, square, triangle, pulse & TTL wave.You would have the resolution of up to 10uHz making this one of the most precise devices available on the market today.
6. GW Instek SFG-1000 (190$)
