How to Use
Begin by connecting the Red Pitaya STEMlab 125-14 to your network via Gigabit Ethernet and accessing the web interface through your browser. The device boots Linux automatically and presents a dashboard with pre-installed applications including oscilloscope, spectrum analyzer, and signal generator. For FPGA development, download the Vivado Design Suite from Xilinx and the Red Pitaya SDK from the official repository. Create your hardware design in Vivado, targeting the Zynq-7010 device, synthesize and implement your design, then generate the bitstream file. Upload the bitstream through the web interface or via SSH to load your custom logic onto the FPGA fabric.
For software development, use the ARM Linux environment to write C, C++, or Python applications that interact with your FPGA design through memory-mapped registers or dedicated IP cores. The Red Pitaya community provides extensive examples and IP cores for common functions like FIR filters, FFT processors, and PID controllers, significantly accelerating development. Connect your analog signals to the SMA connectors on the board, ensuring proper impedance matching and signal conditioning for your specific frequency range. The onboard ADC and DAC operate simultaneously, enabling real-time signal analysis and generation for testing and validation of your designs before deployment to production hardware.
Frequently Asked Questions
What is the maximum input frequency I can sample with the 14-bit ADC?
The ADC supports input frequencies up to 62.5 MHz when sampling at 125 MSPS, following Nyquist theorem. However, the actual usable bandwidth depends on your signal conditioning and the anti-aliasing filter characteristics. For frequencies above 62.5 MHz, you will experience aliasing unless you implement external filtering. The input impedance is 1 megohm in parallel with approximately 100 pF, so proper impedance matching and cable selection are essential for high-frequency measurements.
Can I use this board for high-speed data acquisition beyond 125 MSPS?
The STEMlab 125-14 is limited to 125 MSPS on the integrated ADC. For higher sampling rates, consider the Red Pitaya STEMlab 125-14 with external ADC modules or upgrade to the STEMlab 250-12 model which offers 250 MSPS sampling at 12-bit resolution. Alternatively, you can implement custom high-speed acquisition interfaces using the FPGA fabric and external ADC chips connected via LVDS or parallel interfaces.
Is the FPGA bitstream persistent across power cycles?
No, the FPGA bitstream is loaded from the SPI Flash memory during boot but resides in volatile SRAM. If you power cycle the board, the bitstream will reload automatically from Flash. However, if you want to change the bitstream, you must upload a new one through the web interface or command line. The SPI Flash can store multiple bitstreams, and you can configure the boot process to load a specific design automatically on startup.
What development environments are supported?
The primary FPGA design tool is Xilinx Vivado (free WebPACK edition available). For software development on the ARM processor, you can use GCC, Python, Node.js, or any standard Linux development tools. The Red Pitaya community provides SDKs and examples in C, Python, and MATLAB. Web-based development is also supported through the built-in Jupyter notebook environment, allowing interactive algorithm development and testing directly on the board.
When will I receive my order?
