For engineers working on MIMO communications, quantum control loops, or phased-array radar, the challenge isn’t just capturing high-speed data—it’s maintaining phase coherence across dozens of channels.
As system complexity grows, traditional "big iron" instrumentation often becomes a bottleneck due to fixed channel counts and high costs. At Embedded World 2026, a new modular approach to this problem gained significant attention from the technical press as a viable alternative to $50k+ custom-built racks.
When scaling an RF system, the primary enemy is clock skew and trigger jitter. If two ADCs aren't sampling at the exact same nanosecond, your phase-sensitive data is compromised.
In a recent technical feature, EEWorld Online highlighted how a modular, software-defined approach is replacing expensive, purpose-built hardware:
"The ability to 'mix and match' boards into a single coherent system allows labs to scale without the prohibitive costs... [enabling] multichannel sync and faster streaming for modular instrumentation."
The solution showcased in Nuremberg—officially branded as the X-Channel System 2.0—uses a master-slave clock architecture to transform separate FPGA boards into a single, high-density measurement rig.
Experts at Electronic Specifier and DigiKey noted that this architecture allows engineers to solve three critical problems:
This isn't just theoretical. This technology is already being used in the world’s largest quantum computer in Toronto. By using a shared reference clock distributed via Red Pitaya Click Shields, researchers can run hundreds of synchronized channels with the same precision as a single-board setup.
This vision of "Industrial Scalability" has been echoed across global media, with technical news reaching major networks including AP News, Bloomberg, and the USA TODAY Network.
If you are currently facing a "channel-count ceiling," the consensus from the industry experts is clear: Software-defined, modular synchronization is the most cost-effective path to high-performance RF scaling.
This modular approach was a highlight of the DigiKey Tech Bench at Embedded World 2026, where experts from Electronic Specifier confirmed that the 62.5 MB/s streaming and phase alignment are "essential" for next-gen Edge AI.

To achieve sub-nanosecond alignment, you must distribute a shared reference clock and a common trigger across all boards. If ADCs are not aligned with deterministic timing and low jitter, phase-sensitive measurements will degrade. Systems like the X-Channel 2.0 use LVDS clock fanout buffers to ensure every ADC in the array of samples simultaneously.
Phase coherence means that multiple signals are captured with a fixed and known phase relationship. This is essential for applications like beamforming and direction finding, where the relative timing between channels carries the signal's intelligence.
Modular systems allow you to pay only for the channels you need. You can start with a 2-channel setup and scale to 16, 32, or 64 channels by simply adding more boards to the synchronized cluster, significantly reducing the Total Cost of Ownership (TCO).
Absolutely. The entire system is built on an open-source software stack, allowing you to control the entire synchronized array via Python or MATLAB for automated testing, data logging, and real-time analysis.
