buffer looping repeating the same buffer in the waveform mem ory . Thi s me thod o f
waveform generation decreases memory requirements.
burst trigger mode repeats a stage until a trigger advances the waveform to the next stage
bus the group of conductors that interconnect individual circuitry in a
computer. Typically, a bus is the expansion ve hi cl e to w hic h I/O o r
other devices are connected. Examples of PC buses are the AT bus (also
known as the ISA bus) and the PCI bus.
bus master a type of a plug-in board or controller with the ability to read and write
devices on the computer bus

CalDAC calibration DAC
clock hardware component that controls timing for reading from or writing to
groups
continuous trigger mode repeats a staging list until waveform generation is stopped
conversion device device that transforms a signal from one form to another. For example,
analog-to-digital converters (ADCs) for analog input, digital-to-analog
converters (DACs) for analog output, digital input or output ports, and
counter/timers are conversion devices.
counter/timer a circuit that counts external pulses or clock pulses (timing)
coupling the manner in which a signal is connected from one location to another
CPU central processing unit
DD/A digital-to-analog
DAC digital-to-analog converter—an electronic device, often an integrated
circuit, that converts a digital number into a corresponding analog
voltage or current
