VXI VT1433B, User Manual, Page: 192 / 203

C-Library (interface library)
A library of functions, written in C language, which can be used to operate the
VT1432A and VT1433B.
C-size
One of several possible sizes for VXI modules. The VT1432A and VT1433B are
C-size modules.
channel-dependent commands
Commands that are channel-dependent change a parameter for each channel
independently.
COLA
Constant Output Level Amplifier.
continuous mode
A mode of data-collecting used in the VT1432A, the VT1433B and in other
instruments such as the Agilent/HP E1431A. The instrument collects data
continuously and stops only if the FIFO overflows.
D32, D16 and D08 (EO)
The VXI Bus provides 32 data lines. Modules can use all 32 lines or 16 lines or
8 lines. For example, “D16 access” refers to data read across 16 lines.
daisy-chain
A set of instruments or modules connected together in a line. Data and
instructions enter each one before being buffered and passed out to the next
module in line.
decimation filter
A digital filter that simultaneously decreases the bandwidth of the signal and
decreases the sample rate. The digital filter provides alias protection and
increases frequency resolution. For more information, see
Spectrum & Network
Measurements available through VXI Technology.
delta sigma
A method for converting an analog input to digital data. It involves using a
difference of two voltages (delta) and a summation of signals (sigma) to improve
accuracy.
digitizer
An instrument which converts analog signals into digital data suitable for digital
signal processing.
DRAM
Dynamic Random Access Memory.
