Pentek has added the Model RTR 2757 4U 19-inch rackmount recorder to the company’s Talon Series of recorders.

The new recorder has been designed to work with Pentek's Quartz RFSoC products. The Quartz recorders stream digitized wide bandwidth signals across 100 Gigabit Ethernet. The R 2757 can then capture those streams in real-time at rates of up to 12.5 Gigabyte/s.

“The Quartz RFSoC has gained tremendous popularity with our customers. However, its multi-channel wideband A/D converters produce data at a rate that pushes the limits of data recorders,” stated Chris Tojeira, product director of Pentek's Recording Systems. “We leveraged the performance enhancements of today's storage technology and updated our design architecture to handle these challenging requirements,” he continued.

The RTR 2757 offers both performance and rugged construction. It has up to 122 TB of NVMe (Non-Volatile Memory Express) storage, through high-performance NVME U.2 drives in a RAID0 configuration for very high-speed real-time recording. These drives can be removed from the front-panel that has eight individual drive trays. The independent operating system drive can also be removed from the front panel. The new architecture has improved recording speed by fifty percent over previous generations of Talon recorders.

The RTR 2757’s industrial-grade 4U rackmount chassis carries a dual-Xeon server-class motherboard. The chassis has been optimized for cooling and ruggedized fro use in challenging environments. A QSFP28 optical port is able to support four independent UDP streams for a total real-time recording rate up to 12.5 GB/s (100 Gigabits/s). This recording rate allows the streaming of data from four of the RFSoC's A/D channels over 100 Gigabit Ethernet to capture them as independent files on the recorder. The recorder captures only the Ethernet payload, providing data files similar to other Talon recorders and compatible with the SystemFlow signal analysis tools.

All Talon recorders use Microsoft Windows and include Pentek’s SystemFlow software, which features a GUI, the Signal Viewer and API. The GUI provides intuitive controls for out-of-the-box operation using point-and-click configuration management.

Configurations are easily stored and recalled for single-click setup.
