amplification A type of signal conditioning that improves accuracy in the resulting
digitized signal and to reduce noise.
Am9513-based devices These MIO devices do not have an E- in their names. These devices include
the NB-MIO-16, NB-MIO-16X, NB-A2000, NB-TIO-10, and
NB-DMA2800 on the Macintosh; and the AT-MIO-16, AT-MIO-16F-5,
AT-MIO-16X, AT-MIO-16D, and AT-MIO-64F-5 in Windows.
AMUX devices
See
analog multiplexers.
anlogin.llb
A LabVIEW DAQ library containing VIs that perform analog input with
DAQ devices and can write or stream the acquired data to disk.
anlog_io.llb
A LabVIEW DAQ library containing VIs for analog I/O control loops.
analog input group A collection of analog input channels. You can associate each group with
its own clock rates, trigger and buffer configurations, and so on. A channel
cannot belong to more than one group.
Because each board has one ADC, only one group can be active at any
given time. That is, once a control VI starts a timed acquisition with
group
n
, subsequent control and read calls must also refer to group
n
.
You use the task ID to refer to the group.
analog multiplexer Devices that increase the number of measurement channels while still using
an single instrumentation amplifier.
Also called
AMUX devices.
anlogout.llb
A LabVIEW DAQ library containing VIs that generate single values or
multiple values (waveforms) to output through analog channels.
analog output group A collection of analog output channels. You can associate each group with
its own clock rates, buffer configurations, and so on. A channel cannot
belong to more than one group.
analog trigger A trigger that occurs at a user-selected level and slope on an incoming
analog signal. Triggering can be set to occur at a specified voltage on either
an increasing or a decreasing signal (positive or negative slope).
AO Analog output.
array Ordered, indexed set of data elements of the same type.
