BNC

a type of coaxial signal connector

break-before-make

a type of switching contact that is completely disengaged from one terminal
before it connects with another terminal

breakdown voltage

the voltage high enough to cause breakdown of optical isolation,
semiconductors, or dielectric materials.

C

Celsius

carrier

a main circuit board that provides multiple locations to add sub-circuits or
modules, and a means to connect them

CH

channel

channel

pin or wire lead to which you apply or from which you read the analog or
digital signal. Analog signals can be single-ended or differential. For digital
signals, you group channels to form ports. Ports usually consist of either
four or eight digital channels.

channel clock

the clock controlling the time interval between individual channel sampling
within a scan. Devices with simultaneous sampling do not have this clock.

Channel Wizard

a utility incorporated into MAX that allows you to descriptively name
physical channels in your system

circuit trigger

a condition for starting or stopping clocks

clock

hardware component that controls timing for reading from or writing to
groups

CMRR

common-mode rejection ratio—a measure of the ability of an instrument to
reject interference from a common-mode signal, usually expressed in
decibels (dB)

code width

the smallest detectable change in an input voltage of a DAQ device

cold-junction
compensation

a method of compensating for inaccuracies in thermocouple circuits
