New 32 Bit, 100 MHz PCI Bus Digital Input Card Features Simultaneous Sampling, Software Congifurable Input Width, Differential or Single-Ended CMOS, TTL or ECL Inputs Available and Vast Software Support.
Montreal, Canada ( October 6, 1999) -
Gage Applied Sciences Inc., the leading manufacturer of high quality, high speed Advanced Instruments based on PCI bus, introduces the CompuScope 3200 , a single-slot 32 bit Digital Input card for the PCI bus capable of simultaneous sampling at clock rates up to 100 MHz. With this product, Gage provides the highest PC-based rate of digital data capture available worldwide.

Product Description
The CompuScope 3200 is a state-of-the-art, single-slot, PCI bus card capable of performing 32 bit digital data acquisition of TTL, CMOS or ECL data into on-board memory at up to 100 MHz clock rate. The inputs can be set at the factory to be either differential or single-ended. CompuScope 3200 can also be configured, in software, to be either 8, 16 or 32 bits wide, allowing maximal use of storage memory for 8 bit or 16 bit inputs. Optionally, CompuScope 3200 can be used to stream data across the PCI bus into host memory, making it possible to capture gigabytes of gapless digital data.
Input Circuitry
Experts in high speed analog signal transmission, Gage engineers have provided the best available high speed digital signal paths for the CompuScope 3200.
The input stage of the CompuScope 3200 consists of 34 high speed comparators: 32 for data and one each for clock and trigger. The use of high speed comparators with fully programmable thresholds allows the use of virtually any logic level: 5 TTL/CMOS, 3.3 V CMOS, 2.7 V CMOS, ECL, PECL or even custom logic levels. All digital signal inputs have 50 Ohm Input impedance in order to eliminate signal reflections.
Differential ECL or PECL signals are, by definition, capable of driving a 50 Ohm load and interface seamlessly with CompuScope 3200. For CMOS or TTL signal sources not capable of driving 50 Ohm loads, a special CMOS Buffer Board is available from Gage which buffers the data with 50 ohm line drivers. The output of the CMOS Buffer Board is a 68 pin MDR connector which connects to the CompuScope 3200 using a 6 foot long pleated foil cable, supplied with the CompuScope 3200.
Configurable Input
The output of the on-board comparators is fed into an on-board FPGA which demultiplexes the data from 8, 16 or 32 bits to the 64 bit width required by Gage's high speed memory sub-system under software control. The presence of this FPGA also makes it possible to build customized digital acquisition systems, including front-end data processing, for specific requirements. The only choice customers must make at the time of placing the order is whether they require a differential input or single-ended input CompuScope 3200.
CP500 Based Design
The CompuScope 3200 is based on Gage's popular CP500 PCI board. CompuScope 8500, another CP500 based product, samples analog signals at rates up to 500 MS/s. Conceptually, the main difference between the two products is that the CompuScope 3200 replaces the A/D chips on the CompuScope 8500 with a Digital Input Module. The advantage of a CP500 based design is that virtually all software drivers for DOS and Windows already exist and have previously been tested and proven.
Up to One Billion Samples of Acquisition Memory
The CompuScope 3200 can operate in two modes:
In Memory Mode, it can have up to 16 Megabytes of acquisition memory.
In Real Time Mode, CompuScope 3200 can stream data to host memory for up to 2 Gigabytes (2GB) of acquisition memory.
Multiple Record mode, which allows "stacking" of data from successive triggers, allows more efficient use of acquisition memory by storing only the data around the trigger event.
Fast Data Throughput
The CompuScope 3200 takes full advantage of the fast data throughput offered by the PCI bus. Using Bus Mastering, data can be transferred from on-board memory to the PC's memory at rates up to 100 MB/s - more than 100 times faster than ISA bus and more than 1000 times faster than GPIB!
This throughput allows CompuScope 3200 to be used in test and measurement applications which were previously not possible.
Compatible With GageBit For Windows Software
The CompuScope 3200 is fully supported by the powerful GageBit software for Windows which enables users to operate the card like an logic analyzer without writing a single line of programming code. It allows users to view, manipulate, store, analyze and print data and to convert it to an ASCII format for use in spreadsheets and mathematical software packages.
Typical Applications
Typical applications of the CompuScope 3200 include ADC Testing, Image acquisition, Digital Network Communication Testing, Data capture from Transducers with digital output, Data Bus testing and Digital Circuit testing.
Software Support
Software Development Kits are available for MSDOS, Windows 95/98 and Windows NT. These SDKs support all compilers which can make use of DLLs, such as Visual C++, etc. MATLAB and LabVIEW SDKs are also available.
