A

A

amperes

AC

alternating current

AMM

advanced memory module—used for storing waveform buffers for the
Arb mode of waveform generation. The standard AMM size is
2,000,000 16-bit samples.

amplification

method of scaling the signal level to a higher level

ARB

normal waveform output signal

Arb mode

a mode of generating waveforms in which waveforms are defined by
multiple buffers that can be linked or looped in any order

arbitrary waveform

instrument for generating any desired waveform; this instrument is not

generator

restricted to standard waveforms such as sine or square

ASIC

Application-Specific Integrated Circuit—a proprietary semiconductor
component designed and manufactured to perform a set of specific
functions for a specific customer

AT bus

See bus.

attenuation

decreasing the amplitude of a signal

B

b

bit—one binary digit, either 0 or 1

B

byte—eight related bits of data, an eight-bit binary number. Also used
to denote the amount of memory required to store one byte of data.

bandwidth

the range of frequencies present in a signal, or the range of frequencies
to which a measuring device can respond

BNC

a type of coaxial signal connector

buffer

temporary storage for acquired or generated data

buffer linking

linking different buffers stored in the waveform memory
