The GPIB is a flexible interconnection bus using 15 signals: 8 bit data bus and 7 bits of control lines. Any device on the bus can be a passive listener or an active talker.

Despite the fact that Agilent chose to leave GPIB off of some new instruments, Market Segment Manager Doru Popescu concurs that GPIB is still a popular choice among test engineers, saying: It {GPIB] ...

GPIB is almost 6� to 4� faster than Ethernet for set state tasks and very small transfers. Even though GPIB has the shorter latency and is expected to be faster for small transfers, the ...

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, only come in ...

Here [Chris]’s Ethernet-GPIB adapter provides an easy solution, with both Power over Ethernet (PoE) and USB-C power options. Although commercial adapters already exist, these are rather pricey ...

The host PC must include a suitable GPIB controller—an internal interface card or an external device. Newer PC designs are phasing out traditional internal buses, such as PCI, ISA, and EISA, in favor ...

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 ...

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. Features include: full IEEE 488.2 ...
