buffer looping

repeating the same buffer in the waveform memory. This method of
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 vehicle to which I/O or
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

Celsius

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

D/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
