Description of the GPIB-BUF
This chapter contains general information about the National Instruments
GPIB-BUF and lists components and accessories.
Introduction
The GPIB-BUF, shown in Figure 1-1, is an IEEE 488 (GPIB) data buffer
which increases GPIB performance by isolating a slow GPIB data acceptor
from the rest of the GPIB system. This increase in performance is reflected
both in an increase in the GPIB bandwidth and a quicker release of the
GPIB talker from the task of transferring data to a slow GPIB device. In
most cases, the GPIB talker is a computer with other tasks to perform. The
faster it transfers data, the sooner it can perform its next task.
