an undesirable electrical signal—Noise comes from external
sources such as the AC power line, motors, generators,
transformers, fluorescent lights, CRT displays, computers,
electrical storms, welders, radio transmitters, and internal sources
such as semiconductors, resistors, and capacitors. Noise corrupts
signals you are trying to send or receive.
nonreferenced single-ended mode—all measurements are made
with respect to a common (NRSE) measurement system reference,
but the voltage at this reference can vary with respect to the
measurement system ground
output pin—a counter output pin where the counter can generate
various TTL pulse waveforms
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 work-stations; it offers a theoretical maximum transfer
rate of 132 MB/s.
