Test Platform Offers Expanded Multichannel Synchronization

Red Pitaya recently expanded its multichannel synchronization and high-speed streaming capabilities across its STEMlab 125-14 Gen 2 platform. Developers can now combine multiple STEMlab boards into synchronized, configurable setups, extending input and output capacity while maintaining precise clock and trigger alignment.

With 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, pairing a STEMlab 125-14 PRO Gen 2 with a STEMlab 125-14 4-Input creates a synchronized six-input, two-output system; larger configurations can be assembled to suit specific application requirements. The clock-select architecture allows users to switch between the internal 125-MHz oscillator and an externally supplied reference clock, broadening synchronization possibilities.

The Click Shield architecture handles clock and trigger distribution via the ZL40213 LVDS clock fanout buffer, delivering deterministic alignment with sharp edge control across all boards.

Red Pitaya also enhanced the streaming architecture of its Gen 2 boards, and with software optimization, streaming throughput between board and host computer has increased from 20 to 62.5 MB/s per board.

The updated Deep Memory Mode now supports both acquisition and generation, capturing incoming signals directly into memory or playing back data to the outputs at full core clock speed. It handles both short, high-speed bursts and longer continuous streams at up to 62.5 MB/s across synchronized multiboard setups from standard modular components.
