Red Pitaya has launched a new, updated version of its STEMlab product that is tailored for HF+50MHz SDR and RF applications that require DAQ systems with higher precision.
STEMlab 122.88-16 SDR comes with two 16 bit ADCs, 50 ohm inputs and 14 bit DACs, 50 ohm outputs. It uses the dual core ARM Cortex A9 offering massively better performance, the Xilinx Zynq 7020 FPGA for more real-time processing capabilities plus an ultra-low phase noise 122.88MHz clock which makes new the latest-generation STEMlab more hardware-compatible with HPSDR. 1Gbit Ethernet connectivity has been retained, and RF inputs have been improved in terms of distortion, noise and crosstalk which significantly improves reception and broadens the choice of antenna. STEMlab 122.88-16 SDR retains the original STEMlab form factor so it directly replaces the current platform.
STEMlab is a test and measurement environment that includes a board, an application marketplace and a source code library. It is designed as a low-cost alternative to many expensive measurement and control instruments. STEMlab can function as an Oscilloscope, Logic Analyser, Signal Generator, Spectrum Analyser and more, also performing other tasks like vector network analysis. It is based on high end FPGA technology, enabling software and hardware programming, coupled with very accurate high-end ADCs. Customizable at the FPGA and CPU levels, STEMlab can process real-world signals.
