High speed sampling in a single slot

A single-slot, PCI Bus digitiser card is capable of performing 8-bit analogue/digital conversion at sampling rates of up to 5 Gsamples/s.

A single-slot, PCI Bus digitiser card is capable of performing 8-bit analogue/digital conversion at sampling rates of up to 5 Gsamples/s on two simultaneous channels with 500 MHz analogue bandwidth without a GPIB/IEEE-488 interface bus card.

Available in the UK from Thurlby Thandar Instruments (Tti), the single-slot, full-length card measures just 13.0 x 3.9 x 0.8 in. Oscilloscope-like analogue amplifiers provide low-noise flexible signal conditioning for a wide variety of applications.

The CompuScope 85G uses advanced fast-in/slow-out technology from Tektronix to provide two simultaneous high-quality input channels with wide analogue bandwidth and ultra high sampling rate at a very reasonable cost. An on-chip clocking circuit combined with a robust calibration technique ensures time base accuracy and long-term thermal stability of sampling rates.

The 10,000-point memory can be used as a circular buffer for the storage of pre- and post-trigger data. The user may select fewer than 10,000 points of acquisition for shorter records. Stored data can be transferred to the PC memory for post-processing, display or storage to hard disk without any interface bus.

The CompuScope 85G offers completely programmable input amplifiers including coupling, impedance, gain and offset. Each channel is independently programmable, allowing different settings on different channels.

A wide range of software support is available. Software development kits are offered for C/C++, Matlab and Labview. These can be run under Windows 95/98, Win NT and Win 2000. CompuScope 85G costs £4282.
