Dual-stream PCI Express radar input card

Cambridge Pixel has extended its range of primary radar input cards with the introduction of the dual-stream HPx-400e PCI Express radar acquisition card.

The latest HPx-400e card features two fully independent radar input channels allowing the card to be used by integrators in three discrete ways – for dual sampling of one radar at different sampling rates, for dual redundancy, or for dual-stream capture of two separate radars.

Dual sampling of one radar at different rates provides the flexibility for high-resolution sampling at short-range to get maximum close-in detail and lower data rates at longer ranges to give maximum coverage. In dual redundant mode, the card can be programmed to automatically switch between two radar inputs in the event of loss of trigger, ACP or ARP signal. Alternatively, two connected radars can be processed independently using the HPx-400e thereby reducing the system card count.

David Johnson, CEO, Cambridge Pixel, commented: "The HPx-400e extends Cambridge Pixel's radar interfacing product family with a versatile multi-channel, radar capture capability that offers many advanced features and supports a wide range of radar interfaces. The dual channel feature of the new card will be attractive for specialist radar applications requiring redundant operation or where there is a need to sample the input signal at two distinct data rates."

The HPx-400e continues to provide the signature flexibility of the company's HPx-200 series cards with support for many different radar signal types, including differential and single-ended signals, selectable signal levels and input impedances.
