ADE
application development environment such as LabVIEW,
LabWindows/CVI, BridgeVIEW, Visual Basic, C, and C++
AIGND
analog input ground signal
AOGND
analog output ground signal
AWG
American Wire Gauge
B
BCD
binary-coded decimal
bias current
the small current flowing into or out of the input terminals of an amplifier
bipolar
a voltage range spanning both negative and positive voltages
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 ISA bus and PCI bus.
C
C
Celsius
CGND
chassis ground potential
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.
chassis
the enclosure that houses, powers, and controls SCXI modules
CLK
clock input signal
CMOS
complementary metallic oxide semiconductor
CMRR
common-mode rejection ratio
cutoff frequency
the frequency that defines the upper end of the passband of a lowpass filter
