The STEMlab 125-14 PRO Z7020 Gen 2 is built on the trusted legacy of the original STEMlab 125-14 board, but completely re-engineered to meet the demands of modern industry and research. Designed for applications that require exceptional signal fidelity, low noise, and multi-channel synchronization, this board is ideal for aerospace, quantum, photonics, RF, and automated industrial systems.

Powered by a Zynq 7020 SoC with 1 GB of RAM, the Gen 2 PRO Z7020 offers improved analog front- and back-ends, lower jitter and latency, and a high SFDR of 50 dB. It also supports internal and external clock switching and enables multi-device synchronization through USB-C or Red Pitaya Click Shields. The E3 connector opens up high-speed differential GPIO access and advanced boot options (eMMC, QSPI).

The included software suite features intuitive, web-based measurement tools such as an oscilloscope, signal generator, spectrum analyzer, and more. With support for Python, MATLAB, LabVIEW, and C, the Gen 2 PRO Z7020 integrates effortlessly into advanced testing workflows and automation systems.
