AOC 2025 Spotlight: RADX Technologies and G2 CPU Demonstrate Ultra-Fast Real-Time Signal Analysis

At AOC 2025, Ross Smith from RADX Technologies, alongside Nathan from G2 CPU, demonstrated what they described as the world’s fastest real-time signal analyzer, built on the G2 CPU software toolkit. Running in PXI systems equipped with National Instruments vector signal transceivers, RADX PXI GPUs, and solid-state drives, the solution delivers extreme real-time processing performance for wideband RF signals.
The platform supports more than one billion FFTs per second and achieves 100 percent probability of interception for signals with durations below two nanoseconds. By leveraging NVIDIA-based PXI GPUs for signal processing, the system delivers performance claimed to be 40 to 100 times faster than traditional real-time spectrum analysis solutions, enabling capabilities not previously achievable in PXI-based environments.

The G2 CPU toolkit allows LabVIEW and PXI developers to add real-time spectral analysis, wideband RF record and playback, and continuous streaming to existing PXI systems at a fraction of the cost of dedicated hardware. Live demonstrations showed sustained streaming at 1.25 GSPS directly from an NI vector signal transceiver into a RADX GPU, running continuously for hours with no data loss.

This capability enables full-spectrum visibility for applications such as detecting frequency hoppers and capturing short-duration signals that would otherwise go unnoticed, making the solution well suited for electronic warfare, spectrum monitoring, and advanced RF intelligence applications.
