An inexpensive DDS Signal generator based on the AD9851 module to generate sign wave of up to 70MHz (20-30MHz realistically). The module also has a built-in reference square wave up to 1 MHz, this ...

Arduino programs that allows manipulation of the Si5351 to produce a poor man's Sig Gen. Its a work in progress and there are a few improvements and a few bugs to be fixed. Caveat emptor. My original ...

In this project, the Arduino Uno is configured as a square wave generator with user-selectable control of the frequency and duty cycle.

This waveform generator is explicitly intended to support signal processing learning. This low-cost waveform generator can produce multi-frequency signals with high sampling precision and linearity ...

ERAsynth is an open source, crowd-funded project — now available on Crowd Supply — aiming to make multi-GHz RF signal synthesis accessible to everyone.

Discover how to produce a multiple output arbitrary signal generator cheaply and quickly with low-cost, hobbyist-level microcontroller development boards.

Arduino PWM As you may know, two PWM outputs of Arduino Uno are linked to the timers. For the “common” PWM, if we write a value from 0 to 255 on a PWM pin, the Arduino library will drive the assigned ...

Why buy an expensive oscilloscope, spectrum analyzer, or signal generator, when you can simply download one for free?

Anyone searching for a function generator may be interested in a new DIY Arduino project which details how you can make your very own. “A function generator is a very useful tool, especially ...

We tested the Siglent SDG830 in the Elektor Labs – an arbitrary waveform generator with a frequency range up to 30 MHz with sinusoidal output.
