Optional LAN, GPIB
(IEEE488), and isolated analog programming interfaces are also available.
For example, she says, the VISA command to write an ASCII string to a message-based instrument is the same whether the instrument is GPIB
, USB, or Ethernet.
For example, if a test program uses a declaration to set instrument addresses, only a simple substitution of a VXI-11 address for the GPIB
address is needed to migrate the code.
The solution to this problem is to preconfigure the instruments using GPIB
and then let them execute the tests themselves.
National Instruments has introduced two new GPIB
products - the GPIB
controller and the PCI-8212 combination GPIB
and Ethernet interface for PCI - for engineers and scientists who want to use GPIB
and Ethernet in the same test and measurement system.
SCPI was developed as an extension to IEEE 488 in part because GPIB
never standardized the syntax of instrument commands.
The ability to connect up to 30 Sorensen XC Series units Via a multi-channel RS485 bus that eliminates the need for a GPIB
card in each unit.
As popular computer technology enters the test and measurement arena, and buses such as Ethernet, universal serial bus (USB), and IEEE 1394 are considered for instrument connectivity, questions arise about the future use of GPIB
as the preferred bus for instrument control.
