The HPx-450 is a single- or dual-stream interface card that can be connected to a wide variety of analog and digital radars for high-resolution data capture. Designed with an XMC Switched Mezzanine format, it can be combined with VME, VPX and Compact PCI processor cards to create rugged embedded systems, and features a four-lane PCI Express interface with data transfers of over 500 MB/sec.
The card supports a wide range of different radar signal types, including single-ended, differential, open-collector, and opto-isolated, and analog signals are sampled at up to 125 MHz with a 12-bit A-to-D. Radar video, trigger and azimuth signals are accepted in the form of ACP/ARP or parallel data, and software alarms can be set for loss of triggers or azimuth data.
Dual streams can be set up in a number of ways, including:
- Dual sampling of one radar video at different rates e.g. higher sampling at short ranges for maximum close-up detail, and additional lower sampling across the full range for maximum coverage
- Dual redundant mode – provides software-controlled automatic failover from one input channel to the other in case of loss of trigger, ACP or ARP signal
- Dual independent mode – simultaneous and independent capture of data from two separate radars
The HPx-450 can be provided with an extended operational temperature option.
