HIGH-PERFORMANCE 12-BIT DIGITISER WITH 400 MS/S SAMPLING
27 May 2005 - Thurlby Thandar Instruments Ltd

GaGe Applied Technologies, worldwide leader in the design and manufacture of high-performance PC-based digitiser and oscilloscope cards, has introduced a new high-performance 12-bit digitiser.

The new CompuScope 12400 (CS12400) can reach sampling speeds of up to 400 MS/s, and features the deepest on-board memory available on the market today: up to 4 gigabytes (2 gigasamples). The fast sampling rate enables the capture of high-speed signals with ultra-high timing precision, while the high resolution allows signals with very high dynamic range to be captured.

This combination of speed and resolution are ideal for implementation in a wide range of applications such as radar/lidar system design and test, spectroscopy, communications, ultrasonic non-destructive testing, manufacturing test, as well as signal intelligence and high-performance imaging.

Gage's new finite impulse response (FIR) filtering and signal-averaging field-programmable gate array (FPGA) technologies are also optionally available for the new CS12400 digitiser. The FIR filtering technology allows users to filter digitised data in real time with a completely flexible and user-customisable FIR filter.

Filtering of analogue voltage signals is a powerful method for removing unwanted signal features (like noise) and emphasising particular features of interest in a signal. Data is transparently filtered, with no processing required by the host PC's CPU.

Signal averaging is a powerful method of improving the fidelity of noisy repetitive signals. Using signal averaging, small signals can be extracted from a background of high-amplitude noise, which may even be larger than the actual signal itself.

The CS12400 will take advantage of these new on-board application-specific FPGA technologies offered by GaGe, as well as any new ones that will soon become available.

As with other GaGe products, the CS12400 is available with up to 2 × 10^9 samples of on-board acquisition memory. Deep acquisition memory is useful for applications that require sampling of a long record at a high sampling rate. Examples include radar signal analysis, disk drive testing and signal intelligence. Multiple cards can be configured in master/slave configurations to create a high channel-count system without compromising the acquisition memory depth or sampling rate.

All members of GaGe's CompuScope family, including the new CS12400, are fully compatible with GageScope oscilloscope software, which allows users to acquire and analyse signals without writing a single line of programming code. GaGe also offers software development kits (SDKs) in C/C++, MATLAB and LabVIEW for users that want to create their own custom applications.

GaGe Applied Technologies products are marketed exclusively in the UK by TTi (Thurlby Thandar Instruments).

About: Thurlby Thandar Instruments Ltd
TTi (Thurlby Thandar Instruments) is a major European manufacturer of electronic test and measurement instruments.

These products are sold throughout the world via distributors and agents.

Within the UK, TTi sells both its own manufactured products and a wide range of instruments from other European, American and Japanese manufacturers.

TTi is located in Huntingdon near Cambridge in England.

The origins of TTi date from the late 1970s when two separate companies, Thurlby Electronics Ltd. and Thandar Electronics Ltd. were both designing and manufacturing electronic test equipment within close proximity at St. Ives in Cambridgeshire.

Through the 1980s, Thurlby specialised in bench power supplies, high resolution multimeters and digital storage units; whilst Thandar specialised in function generators, frequency counters and logic analysers.

In 1989 the two companies were merged into a new organisation - Thurlby Thandar Instruments Ltd. - and located to larger premises in nearby Huntingdon.

Through the 1990s the existing product ranges were expanded and new product areas developed including arbitrary waveform generators, EMC measurement equipment and component bridges.

In 1999, TTi acquired the product ranges of Black Star Instruments and incorporated them into the TTi range.

In addition to selling the TTi range of products throughout the world, the company has also expanded its UK sales operation to represent other major producers of test equipment.

Today TTi is one of the foremost producers of general purpose electronic test instruments and laboratory power supplies in Europe, selling products in over fifty countries.

It is also one of the largest distributors of test and measurement equipment in the UK representing many leading American, European and Japanese producers within the United Kingdom market.
