OpenVPX and the SOSA standard are two reference frameworks used for modular systems in the defense and aerospace industries. OpenVPX, based on the VPX standard, focuses on defining mechanical, electrical and thermal interfaces to ensure interoperability between modules from different suppliers. The SOSA (Sensor Open Systems Architecture) standard, on the other hand, goes a step further, integrating not only hardware interoperability aspects but also software specifications and communication protocols, thus promoting greater modularity and flexibility in the development of sensor and processing systems.

Our VPX card intelligently combines these two standards, leveraging the robustness and hardware interoperability of OpenVPX while incorporating the software and communication advances of the SOSA standard.

Equipped with 4 channels of 20 Gsps 12-bit ADC and 4 channels of 28 Gsps 16-bit DACs, the system offers a comprehensive solution for high-speed data acquisition and processing, including Direct Sampling capabilities.

RF Direct Sampling for enhanced performance and scalability

Recent advancements in data converter technologies have led to a substantial increase in the sampling rate, opening up the potential to achieve a bandwidth of several tens of gigahertz for the most recent ADCs and DACs.

Many applications involving RF digitization use a method known as intermediate frequency (IF) sampling, where the analog signal is first converted to a lower intermediate frequency before being sampled by a converter.

Increasing sampling rates allow for direct sampling of the RF signal without the need for additional RF conversion stages, even for signals in the tens of gigahertz range. This approach, known as direct sampling, is now applicable to a wide range of radar and EW frequency bands, including the Ku, K, and Ka bands.

The RF direct sampling method can greatly simplify architectures and enhance the flexibility, scalability, and SWAP-C of equipment.
