VT1433B User's Guide

Glossary

DSP

Digital Signal Processing.

DTB arbitration bus

The VT1432A does not use the arbitration bus. The arbitration bus is part of the VXI specification and is used by some modules to request bus control.

ECL

Emitter-Collector Logic, a standard for electrical signals.

Engineering Unit (EU)

A scale factor used to convert the output of a transducer (in volts) into another unit (for example: g’s).

FFT

Fast Fourier Transform.

FIFO

First-In First-Out. A buffer and controller used to transmit data. The FIFO in the VT1432A/33B input is implemented using DRAM.

freerun counter

A counter in which the bits always increment. When the freerun counter reaches all ones it resets to all zeros and continues counting.

Fs

Sample Frequency or sample rate.

group ID

Any number of channels may be declared and uniquely identified by a groupID. A channel can be a member of more than one group.

holdoff time

A circuit that detects a trigger signal will not respond to another trigger until the holdoff time has passed. This prevents a ringing signal from be detected as multiple triggers.

IACK

Interrupt ACKnowledge.

ICP®

Integrated-Circuit Piezo-electric transducer.

IRQ

Interrupt ReQuest.

G-3
