Waveform acquisition and replay moves up to GHz range

The combination makes it possible to capture high frequency signals up to the GHz range and continuously store them for hours on end or lower frequency signals for even longer periods of time.

Each Tera-store system can house up to six digitiser cards making it possible to configure instruments with 1 to 96 fully synchronous acquisition channels. If more channels are required then a 16 slot docking station can be added to expand the system up to 256 channels.

A wide selection of digitisers is available offering sampling rates from 100 kS/s up to 5 GS/s with resolutions of 8, 12, 14 and 16 bit. The systems can also be used with AWG cards to create replay systems that can have from 1 to 24 channels.

A wide range of AWG cards is available offering output rates from 20 MS/s up to 1.25 GS/s with 8, 14 or 16 bit resolution.

At the heart of the platform is a carefully selected, base PC system. This powerful computer includes a Supermicro 4U/Tower with 8 drive bays and 6 free PCIe slots for digitiser or generator cards.

The PC is powered by a Xeon Quad Core 2.4 GHz processor, has on-board graphics, 8 GB RAM, a separate 256 GB SSD for the system installation, a DVD drive, and runs under Windows 7 Professional.

The chassis also hosts a powerful 865 W power supply with whisper quiet, fan-based cooling.

The Tera-store streaming solutions are complete turn-key systems and come factory configured with Spectrum's Sbench 6 Professional software for digitiser control, data capture, display and analysis. Sbench 6 is optimised to ensure the fastest possible data transfer speeds and allows the use of all the possible acquisition modes such as single shot, segmented acquisitions, or continuous streaming (FIFO).

The program comfortably handles large data files and makes it easy to setup an acquisition, then view, analyse and document the result.

The systems are available with a choice of streaming rates, from 400 MB/s up to 3 GB/s, and storage capacities, from 1 TB to 32 TB. The various options consist of a high performance RAID controller and a number of solid-state or hard-disk drives (SSD/HDD's) that are configured to support the required transfer rates and storage times.

Spectrum integrates the complete system, providing full factory configuration and performance testing. This includes the PC setup, software and hardware installation, as well as digitiser calibration.  Both the hardware and software are optimized and tested to guarantee the specified streaming rates.

Tera-store systems are suited to applications where continuous data acquisition or replay is required or large volumes of data need to be collected, stored and analysed. Examples include research and development in communications, radar, media testing, automation, imaging, science, transport, surveillance, aerospace and defence.
