GAGE Applied Technologies, represented by Emona Instruments , the CompuScope 12400 (CS12400) 12-bit digitiser. It can reach sampling speeds up to 400MS/s and has an onboard memory of up to four gigabytes (two gigasamples).

Its sampling rate enables the capture of high-speed signals with ultra-high timing precision and 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 Finite Impulse Response (FIR) filtering and Signal Averaging Field-Programmable Gate Array (FPGA) technologies are also available for the digitiser. The FIR filtering technology allows users to filter digitised data in real time with a flexible and user-customisable FIR filter.

Filtering of analogue voltage signals allows the removal of unwanted signal features and emphasising signal features of interest. Data is transparently filtered with no processing required by the host PC's CPU.

Signal averaging improves 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 onboard application-specific FPGA technologies. The system is available with up to two billion samples of onboard 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 as Master/Slave to create a high channel count system without compromising the acquisition memory depth or sampling rate.

The CS12400 is compatible with GageScope oscilloscope software that allows users to acquire and analyse signals without writing any 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.
