How to Generate a High-Precision Waveform Using a DAC and a Custom PCB

In this article, we’ll develop firmware that will serve as the basis for high-precision, high-speed signal generation. I recently designed an arbitrary waveform generator (AWG) PCB that is built around a C8051F360microcontroller and a TxDAC from Analog Devices. These two ICs communicate via a parallel interface that allows me to generate higher-frequency analog signals by seeking …

moRFeus – A field-configurable wideband frequency converter and signal generator

MoRFeus is a 30 MHz–6 GHz field-configurable Fractional-N wideband frequency converter and signal generator. Its LCD display and button interface enable dynamic field-level configuration – from switching between signal generator and other modes, to setting the local oscillator frequency and more. It was designed for wideband frequency up- and down-conversion – with an LO frequency …
