Pentek has added the Model RTR 2742 4U 19-inch rackmount recorder to the company’s Talon series of recorders.

The Talon RTR 2742 is designed to be a record and playback system for ultra-wideband analog RF/IF signals. The system uses two 12-bit, 6.4 GHz A/D converters to provide sustained recording of 2.4 GHz bandwidth signals at rates up to 6 GBytes per second. It is able be configured as a one- or two-channel system and it can record real samples or complex I+Q digitally down-converted samples.

The 16-bit, 6.4 GHz D/A converter allows the RTR 2742 to play back analog signal bandwidths up to 1.28 GHz. The device has integrated digital down- and up-converters to provide flexible bandwidth and tuning frequency selection for both recording and playback.

“Many communications and radar applications operate across ultra-wideband frequencies. Now we can satisfy the many customers who need to digitize and record these signals with bandwidths as high as 2.4 GHz,” noted Rodger Hosking, vice-president, Pentek. He added, “With the Talon RTR 2742, engineers can capture the whole spectrum in a single wideband channel, eliminating the need to break up the signal into smaller bands, covering adjacent slices of the spectrum.”

The RTR 2742 comes in an industrial grade 4U 19-inch rackmount chassis with hot-swappable data drives, front-panel USB ports and I/O connectors on the rear panel. The chassis is optimized for cooling and ruggedized for challenging environments.

The RTR 2742’s 12-bit 6.4 GHz A/D can be clocked at rates from 1.6 to 6 GHz in single-channel mode. Data can be truncated and packed as 8-bit samples, to support continuous recording up to the maximum sample rate. The D/A is capable of reproducing signals with up to 1.28 GHz of instantaneous bandwidth and includes a wide range of interpolations. The RTR 2742 provides up to 122 TB of front panel removable solid-state storage for hours of real-time, high-bandwidth signal recording.

The Talon recorder range uses the Microsoft Windows platform and features Pentek’s SystemFlow software, with GUI, Signal Viewer and API. Configurations can
