By using Red Pitaya Click Shields and shared clock distribution, users can synchronize combinations of STEMlab 125-14 PRO Gen 2, STEMlab 125-14 PRO Z7020 Gen 2, STEMlab 125-14 4-Input, and SDRlab 122-16 boards into a single coherent measurement system. For example, combining a STEMlab 125-14 PRO Gen 2 with a STEMlab 125-14 4-Input creates a synchronized system with 6 inputs and 2 outputs, and even larger configurations can be assembled to suit the needs of each application.

This increased flexibility is based on the clock selection architecture first introduced in the STEMlab 125-14 4-Input, which allowed switching between the internal 125 MHz oscillator and an external clock reference. With this same functionality now available across the entire Gen 2 125-14 family, synchronization possibilities have been significantly expanded. The Click Shield architecture manages clock and trigger distribution using the ZL40213 LVDS clock distribution buffer, providing deterministic alignment with precise edge control across all boards in a configuration.

Along with synchronization improvements, Red Pitaya has also significantly optimized the streaming architecture of its Gen 2 boards. Thanks to software optimizations, data transmission throughput between the board and the host computer has increased from 20 MB/s to 62.5 MB/s per board, enabling much higher sustained data rates for both signal acquisition and generation.
Deep Memory mode now supports both acquisition and generation, capturing signals directly into memory or streaming data to the outputs at the full core clock speed. The enhanced streaming application allows for both short bursts of high-speed transmission and longer continuous streams of up to 62.5 MB/s. All of these modes also work in synchronized multi-board configurations, enabling the creation of high-performance distributed systems using standard modular components.

“These updates reflect what our users have been asking for: the ability to scale their systems without sacrificing accuracy or speed,” said Mateja Lampe Rupnik, CEO of Red Pitaya. “With expanded multi-channel synchronization and an improved streaming architecture, engineers can now build custom instrumentation with a high number of channels using our standard boards, dramatically reducing the cost and complexity of what previously required custom-designed hardware.”
