Red Pitaya’s STEMlab 125-14 is a low-cost, open-source platform for integrating low-noise, high-stability measurement-and-testing capabilities into OEM devices for applications including automotive, aerospace, telecommunications, medical, and software defined radio.
Out of the box, this compact, easy-to-integrate board (14 x 10 x 4.5 cm, 0.4 kg) allows remote connection to a range of free, web-based measurement tools to support your application, without the requirement for installing proprietary software. These tools include:
- Oscilloscope & signal generator
- Spectrum analyser
- LCR meter
- Bode analyser
- Logic analyser
- Vector network analyser
Users can also develop their own tools to support an end product.
The STEMlab 125-14 features 2-input, 2-output RF connectivity via SMA, both running 125 Msps at 14-bit resolution with a bandwidth from DC to 60 MHz. The full-scale input of the device is ±1 V and ±20 V at 1 MΩ / 10 pF (absolute max. 30 V). The device can output at ±1 V (50 Ω) with a slew rate of 2 V / 10 ns.
The Red Pitaya board can be controlled remotely over LAN (1 Gbit ethernet) or wireless networks (requires Wi-Fi dongle) using familiar research-level languages such as Python, MATLAB, and LabVIEW. The open-source nature of Red Pitaya also allows users to turn this pocket-sized multi-instrument device into a DSP development board, DAQ card, or FPGA development board.
For those looking to program their own functionality, the STEMlab 125-14 also serves as a Linux single-board computer powered by a dual-core Arm Cortex-A9 processor supported by 512 MB RAM. System memory is provided through a micro-SD card with up to 32 GB storage, and Red Pitaya provides a lifetime license to Jupyter Notebook and a list of C code functions to enable users to access full control of the board. Free code is also available on Github for programming the on-board Xilinx Zynq 7010 FPGA (7020 for the low-noise version of this board).
Connection to the board’s other interfaces is provided via extension headers for 16 digital IOs, 4 analogue inputs (0-3.5 V, 12 bit at 100 kS/s), 4 analogue outputs (0-1.8 V), and other standard interfaces. The STEMlab 125-14 can be powered using the micro-USB port (5 V, 2 A max.), and boards can be daisy-chained over SATA connection (up to 500 Mbps) for more-demanding workloads.
If you’ve got a commercial project that requires on-the-go signal analysis, Red Pitaya has a solution, so fill out the form below, and ipXchange will get you connected. A range of application-specific variants of this board are available, including a 4-input version with a larger FPGA, so get a chat going, and Red Pitaya will direct you to their best board(s) for your project.
