Additionally, you can opt to use DAC pre-equalization to flatten the DAC response. In this article we will learn how quickly and easily we can build our own Function generator using Arduino. This compensates for the effect of the DAC's zero-order hold, which rolls off high frequencies. 740 Lomas Santa Fe Dr Please fill out the contact form below and we will reply as soon as possible. The desired waveform may be described by a mathematical function, and each discrete value of the function is stored as a digital word in a memory. This python module lets you define synchronized waveforms and sample them to be output through a multi-channel DAC. In this programming example, we create a 10 point arbitrary waveform that starts at the least-significant bit and steps up to the most . I have attached the following.
