Description

The NEW Avalon AE9000FW-1000 SIGINT Disk Recorder is designed to record a 3 GHz analogue IF (intermediate frequency) signal at a bandwidth of up to 1 GHz. The upper half of the unit includes the Analogue signal processing electronics (to the rear) and supporting assemblies and sub-assemblies, including (left to right): LED indicators, USB Port, System Disk (removable), TOC (table of contents) Disk (removable) and Docking Port for a portable Archive Disk. Multi-channel data interfaces are also available.

AE9000-FW series recorders also include an SPF/QSPF interface for networking communications, with support for both fibre optic and copper cable. Protocols supported (within the SPF/QSPF specification) include: Ethernet (10Gbits/s 40GBits/s), Fibre Channel and InfiniBand.

The lower half of the unit comprises the digital signal processing, power supply and a pair of removable Disk Packs containing the storage media. The baseline storage configuration comprises twelve 1 TB Multi-level Cell (MLC) solid-state disk drives (SSD) per Disk Pack, giving 24 TB of storage capacity in the most rugged possible package.

AE9000FW-1000 utilizes a preliminary frequency translation from the input IF centre frequency of 3 GHz to a lower frequency centred in the region of 825 MHz, still with the required 1 GHz bandwidth. The necessary image suppression filtering is provided as part of the translator block. The signal is then digitised by a 12-bit ADC (analog to digital converter) followed by digital signal processing to the final recordable data rate.

The recorder is able to reconstruct the recorded digital samples and output these in their original analogue form. During Stop and Record, the output signal is derived from the Record Input Signal. During Play, the output is derived from the data stored on the disk system. During Stop, Record and Play, the reconstructed analogue output is a 1 GHz bandwidth centered on a 3 GHz IF. Independent Record and Play is possible at 50% of full Bandwidth i.e. Record and Play at 500 MHz.

Unlike previous generations of Avalon disk recorders, AE9000FW-1000 records data in a standard computer file format, thereby simplifying the selection and copying of critical sections of recorded data. Data selection typically takes place either at the Tables tab or at the Timeline tab. The user may elect to save extracted data to any of the following media targets: plug-in SATA Archive Disk Drive, attached USB memory device (if permitted), networked disk drive, RAID or SAN. Extracted data files can be saved with community-standard “attached” or “detached” headers, if required.
