The Avalon AE9110 SIGINT data recorder is designed to record an 800 MHz analogue IF (intermediate frequency) signal at a bandwidth of up to 1 GHz.  The upper half of the unit incorporates the Digital and Analogue signal processing electronics.  Multi-channel data interfaces are also available.  The recorder also includes an interface for networking communications, with support for both fibre optic and copper cable.  Protocols supported include: Ethernet (10Gbits/s) and Fibre Channel.

The lower half comprises a pair of removable Disk Packs containing the storage media. The baseline storage configuration comprises eight 1 TB Multi-level Cell (MLC) solid-state disk drives (SSD) per Disk Pack, giving 16 TB of storage capacity in the most rugged possible package.

AE9110 accepts an input IF centre frequency of 800 MHz and supports a recording bandwidth of 1 GHz.  The signal is then digitised by a 12-bit ADC (analogue-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 modes, the reconstructed analogue output is a 1 GHz bandwidth, centred on an 800 MHz IF.

The AE9110 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 optional media targets: plug-in SATA Archive Disk Drive, attached USB memory device (if permitted), networked disk drive, RAID or SAN.  Extracted data files are saved with community-standard “attached” or “detached” headers.
