CompuScope 1220 product introduction

CompuScope 1220 is 12 bit dual channel, 20 MS/s waveform digitizer card for the PCI Bus.

Recognizing that until very recently, almost all multi-Megahertz data acquisition was done using Digital Storage

Oscilloscopes under GPIB control, Gage has ported all the features of these DSOs onto the CompuScope card.

This means that you do not have to rethink the solution in terms of a completely unknown data acquisition card.

You can simply develop the data acquisition system as if an oscilloscope were being used, but instead use a

CompuScope card to take advantage of its attractive price and performance.

Of course, CompuScope cards are much more than just another DSO under GPIB control:

•

CS1220 features up to 1 billion samples of on-board acquisition memory.

•

Multi-card Master/Slave systems provide from 2 to 16 channels of simultaneous A/D conversion, something

normal DSOs simply cannot do.

•

Data transfer rates from CompuScope memory to PC memory run as high as 50 MB/s for the CS1220 as

compared to a few hundred KB/s for GPIB.

•

CompuScope cards are easier to program, as Software Development Kits are available for C/C++,

MATLAB and LabVIEW.

•

CompuScope cards are installed inside the PCI bus chassis, so there is no external box such as a DSO.

•

CS1220 cards have standard features such as Multiple Record, which help optimize the use of the on-board

memory by stacking data from successive bursts.

•

You can also write software for a multi-card system in which all the cards are not in a Master/Slave

configuration. Drivers supplied by Gage support all these multi-card configurations.

Special features of the CompuScope 1220 include:

•

Bus Mastering

CompuScope 1220 cards are fully capable of becoming a bus master in order to transfer data at the

maximum rate of 50 MB/s.

A bus Master is a card that can take control of the bus and transfer data to any PCI target device such as

system RAM without any involvement from the CPU.

•

External Clock

CompuScope 1220 comes standard with External Clocking capability that allows synchronization of the

digitizers with an external system.
