the technique of using an optoelectric transmitter and receiver to transfer
data without electrical continuity, to eliminate high-potential differences
and transient signals
to provide coupling with electrical isolation between input and output.
Sometimes called optoisolator or photocoupler.
output
the amount of time required for the analog output voltage to reach its final
value within specified limits
the maximum rate of change of analog output voltage from one level to
another
a bundle of data organized in a group for transmission
a type of SCXI operating mode in which the module sends each of its input
channels directly to a separate analog input channel of the device to the
module
the range of frequencies which a device can properly propagate or measure
a type of handshaked (latched) digital I/O in which internal counters
generate the handshaked signal, which in turn initiates a digital transfer.
Because counters output digital pulses at a constant rate, this means you
can generate and retrieve patterns at a constant rate because the handshaked
signal is produced at a constant rate.
personal computer
a credit-card-sized expansion card that fits in a PCMCIA slot, often referred
to as a PCMCIA card
Peripheral Component Interconnect—a high-performance expansion bus
architecture originally developed by Intel to replace ISA and EISA. It is
achieving widespread acceptance as a standard for PCs and workstations;
it offers a theoretical maximum transfer rate of 132 Mbytes/s.
