range of frequencies present in a signal, or the range of frequencies to
which a measuring device can respond
bus
T
h
e
group of connectors that interconnect individual circuitry in a
computer. Typically, a bus is the expansion vehicle to which I/O or other
devices are connected. The ISA and PCI-buses are examples of PC buses.

n
adaptation of the Peripheral Component Interconnect (PCI)
Specification 2.1 or later for industrial and/or embedded applications
requiring a more robust mechanical form factor than desktop PCI. It uses
industry standard mechanical components and high performance connector
technologies to provide an optimized system intended for rugged
applications. It is electrically compatible with the PCI Specification, which
enables low cost PCI components to be utilized in a mechanical form factor
suited for rugged environments.

A method of propagating signals along a bus in which the devices are
prioritized on the basis of their position on the bus
data acquisition—collecting and measuring electrical signals from sensors,
transducers, and test probes or fixtures and inputting them to a computer for
processing
