TAMS 81488 card sets a new standard for IEEE488.2 performance.

Maximum I/O Performance

I/O performance is imperative in instrument control. The computer should always be waiting for the instrument and not the other way around.  The TAMS 81488 can deliver all the speed that your instruments need.  

By moving software functions into hardware and concentrating on improving the performance of small transactions the 81488 is able to offer real world performance improvements.

Speed Considerations

Using a single number to characterize performance of GPIB, or any type of I/O operation can be misleading.  There are many factors that affect actual performance: the amount of data being transferred; the size of data blocks; the difference between read and write speeds; programming language; the computer being used; etc. As a result, we do not recommend basing any decisions on maximum transfer rate.  However, to conform to the industry standard of specifying maximum I/O speed, the TAMS 81488 card can be specified to exceed 1MB/s. In addition, our tests have shown the 81488 to be 4.5 times than the 80488 for small transactions.


The TAMS 81488 is fully compliant with the PCI specifications for 3.3V and 5V PCI or PCI-X slots and delivers the highest possible level of throughput.  The card operates with 32 bit or 64 bit signaling specified at 33, 66, 100 or 133MHz, allowing complete configuration flexibility.  Whether you are using Basic for Linux or programming in C with the SICL or VISA library, your code will run at full performance.
