What is an IEEE 488 standard bus?
IEEE 488 is a short-range digital communications 8-bit parallel multi-master interface bus specification developed by Hewlett-Packard as HP-IB (Hewlett-Packard Interface Bus). It subsequently became the subject of several standards, and is generically known as GPIB (General Purpose Interface Bus).
Why IEEE 488 bus is used in microprocessor based measuring instruments?
Figure 6.28 shows a block diagram of a microprocessor based impedance measuring instrument. The operation makes interface with the instrument via the IEEE 488 bus to allow control by, or to make the measurement available to, a large external computer system.
What is GPIB cable?
What is GPIB? GPIB (General Purpose Interface Bus) was developed as an interface between computers and measuring instruments. It is mainly used to connect PCs and measuring instruments.
How many devices can be connected to a single IEEE 488 Bus?
15 devices
Interconnection Cabling Any individual IEEE-488 bus is limited to 15 devices including the controller.
What is the size of the address bus and data bus in 8086?
It is a 16 bit µp. 8086 has a 20 bit address bus can access upto 220 memory locations ( 1 MB) . It can support upto 64K I/O ports. It provides 14, 16-bit registers.
How many devices can be connected in a single IEEE 488 bus?
What is GPIB device?
The GPIB interface, sometimes called the General Purpose Interface Bus (GPIB), is a general purpose digital interface system that can be used to transfer data between two or more devices. It is particularly wellsuited for interconnecting computers and instruments.
