System Configuration Effects on HS488
Maximum HS488 data transfer rates can be limited by your host computer and GPIB system setup. For example, when using a PC-compatible computer with PCI bus, the maximum obtainable transfer rate is 8 Mbytes/s, but when using another bus, such as USB or Ethernet, the maximum data transfer rate depends on the maximum transfer rate of that bus.
The same IEEE 488 cabling constraints for a 350 ns T1 delay apply to HS488. As you increase the amount of cable in your NI-488.2 configuration, the maximum data transfer rate using HS488 decreases. For example, two HS488 devices connected by two meters of cable can transfer data faster than four HS488 devices connected by four meters of cable.
