GPIB (the physical layer) is a bit of a nightmare, but many even remotely modern devices have a USB or RS232 connection which uses the same SCPI (the application layer) command set.

In the May 1994 issue of Test & Measurement World, I stuck my neck out and wrote Look over your shoulder, GPIB where I predicted that the venerable instrument bus would be overtaken by Ethernet and ...

Immune thrombocytopenia (ITP) is a common bleeding disorder caused primarily by autoantibodies against platelet GPIIbIIIa and/or the GPIb complex. Current theory suggests that antibody-mediated ...

GPIB, however, has a shorter latency than Ethernet. Typical GPIB latency is about 100 �s while Ethernet is in the 1,000-�s range. This gives GPIB a 10� latency advantage over Ethernet.

GPIB is also used to connect VXI and PXI systems to external controllers. In addition, some specialized instruments, like Keithley's recently introduced Model 2800 RF power analyzer, ...

The older model Agilent 82357B USB-GPIB adapters are around $100, and will actually work on most platforms. I use this with the HP 3457A and HP 6625A setup to run through automated testing.

Figure 1 This USB-based GPIB controller requires only four ICs. Advertisement. The design uses the FT245BM USB-controller IC from Future Technology Devices International Ltd, which features an 8-bit ...

Engineers and scientists now can use the latest USB standard, USB 2.0 high-speed, to control GPIB instruments at transfer rates of up to 8 MBytes/sec. The new National Instruments GPIB-USB-HS, claimed ...

GPIB Interface Card. July 1, 2006. The PCI-1671UP is designed as a cost-effective, universal PCI, GPIB controller in MD1 low-profile form factor, which allows for data transfer rates of up to 1.5MB/s.
