Create high performance excitation test systems using MATLAB and arbitrary waveform generators
Arbitrary waveform generators (AWGs) have become essential tools for test engineers, especially when dealing with PCB prototypes, silicon components, or high-frequency modulated signals in RF technology. While having separate pulse, function, modulation, and RF generators on the bench can be useful, using an AWG offers greater flexibility and precision. By directly synthesizing signals from stored samples, AWGs allow for precise control over waveform generation, ensuring repeatability and accuracy.
The flexibility of AWGs comes from their sample-based structure, which is essentially the opposite of how a digital oscilloscope operates. While an oscilloscope captures analog waveforms and converts them into digital samples, an AWG reconstructs analog signals from stored digital samples using DACs. This enables the creation of virtually any waveform—ranging from simple sine waves to complex serial digital pulses.
Unlike traditional signal generators that often produce only one type of waveform, such as a sine wave, AWGs use direct digital synthesis techniques to generate signals that include advanced features like jitter, noise, and inter-symbol interference (ISI). These characteristics can be programmed through software tools, making it easier to define and simulate real-world signal behavior.
Modern AWGs are keeping pace with the rapid advancements in electronics and RF technologies. They now offer high sampling rates, long waveform memory, deep dynamic range, and sufficient resolution to meet even the most demanding applications in defense, high-speed serial communication, optical networking, and research.
One of the key specifications of an AWG is its sampling rate. A few years ago, this was around 24 GS/s, but today’s models can reach up to 50 GS/s. This allows AWGs to generate wideband RF signals up to 20 GHz and high-speed baseband signals at up to 122.5 Gb/s, while still maintaining the vertical resolution needed for complex modulation schemes like OFDM and high-order QAM.
AWGs are increasingly becoming the go-to solution for various testing and measurement scenarios due to their numerous advantages. For example, stored signals can be modified in multiple ways, such as filtering, convolution, time shifting, and modulation. Additionally, by changing the sampling clock frequency, the output frequency can be adjusted without altering the waveform itself. Anomalies like transients or drops can also be added anywhere in the waveform, simulating real-world conditions like sinusoidal jitter during prototyping.
Moreover, direct digital synthesis technology can be used in conjunction with design tools to model component, channel, and system performance. Software-based editing tools further simplify waveform development and modification, making it easier for engineers to create and test complex signals.
As signal complexity increases, software-based tools have become the preferred method for waveform creation. Advanced tools can generate waveforms from mathematical functions, reuse code, and model the resulting signals. Whether you're using basic waveform files or more sophisticated tools like MATLAB, there's a wide range of options available.
MATLAB, a powerful tool developed by MathWorks, provides engineers with a comprehensive set of mathematical operations, analysis, and DSP functions. It allows for faster computation compared to general-purpose programming languages. MATLAB's Instrument Control Toolbox also facilitates communication with instruments like AWGs, supporting protocols such as GPIB, VISA, TCP/IP, and UDP.
Creating waveforms in MATLAB involves defining parameters, generating the waveform, initializing the connection, setting markers, transferring the data to the instrument, configuring the output, and enabling the channel. With the help of GUIs built in MATLAB, users can interact with the AWG more efficiently, streamlining tasks like waveform creation, parameter adjustment, and signal generation.
In conclusion, the use of high-performance AWGs for direct digital signal generation has become a cornerstone for many modern applications, including wireless communication measurements and serial compliance testing. With powerful software like MATLAB, engineers can create, modify, and simulate almost any waveform, enabling accurate and efficient testing in real-world conditions.
