Data Acquisition - Analog Front End (AFE)

The AFE2124E/1KG4 is an integrated data acquisition system designed to facilitate the gathering of analog signals into a digital domain. It is designed to work in high-accuracy, low-power requirements, while providing excellent data acquisition capability. The AFE2124E/1KG4 offers an outstanding performance, providing the user with real-time multi-channel data collection and high-speed data processing.

The system is comprised of an analog front end (AFE) with inbuilt precision data processing functions, and a data acquisition board for conveying the analog signals to the digital domain. The AFE2124E/1KG4 enables sampling rates of up to 500kHz, and offers a wide range of DC precision (as low as ±0.25µV). The system also accepts multiple gain ranges, with gains of up to 32V/V. The AFE2124E/1KG4 includes an integrated data converter with 12-bit resolution, allowing for the collection of both high precision and high frequency data. It has an integrated temperature sensor to compensate for drift in the measurement over time.

The AFE2124E/1KG4 is ideally suited to applications such as electrochemistry, high impedance voltage/current sensing, sensor/transducer characterization, and strain/pressure gauge testing. Its accuracy also renders it suitable for use in laboratory experimentation. Moreover, its communications interface makes it well-suited to remote sensor and temperature monitoring.

The working principle behind the AFE2124E/1KG4 system is based on converting signals from its analog stage to the digital data format. The system is an intimate combination of an analog to digital (A/D) converter and a high-speed digital signal processor (DSP). The A/D converter receives data from the analog sources, converts it to digital data, and transmits it to the DSP. The DSP is responsible for the data processing and formatting which, when combined with the microcontroller and the DSP aboard the board, allow for high-speed data transfer. The board also connects to external data sources including Pressure, Temperature, Flow and Strain Sensors.

Once data is conveyed from the analog stage to the digital domain, it is divided into blocks, and each block is processed in stages to enable data manipulation. This involves separation of the signal into different components and connecting them to the particular device it is intended to control. The board then applies an advanced filtering process to the data, which removes unwanted frequencies and noise, ensuring a clean signal. Further manipulation is required depending on user requirements, and this may include features such as time synchronization, signal processing algorithms and signal measurements, the latter providing a variety of important information.

The AFE2124E/1KG4 is a powerful and highly customizable integrated data acquisition system. Its advanced signal processing and signal manipulation capabilities allow for efficient data capturing from a variety of sources in a wide range of applications. It provides unprecedented accuracy and reliability, allowing for the collection of high precision data, even in difficult environments. By taking advantage of its impressive data acquisition capabilities, it is possible to gain invaluable insights and accuracy into different processes.
