National Instruments Measure Data Acquisition T, U

SCXI Signal Conditioning eXtensions for Instrumentation. The

National Instruments product line for conditional low-level

signals within an external chassis near sensors, so only

high-level signals in a noisy environment are sent to data

acquisition boards.

sec Seconds

single-ended inputs Analog inputs that you measure with respect to a common

ground.

software trigger A programmed event that triggers an event such as data

acquisition.

Synchronous A method of data communications in which a prearranged

number of bits are transferred per second. Synchronization

occurs before and after the transmission of blocks of data, rather

than before and after every character. There are no start bits or

stop bits, as there are in asynchronous communications. All

transmitted bits represent information or are parity bits. See

Asynchronous.

T

trigger A condition for starting or stopping clocks.

U

unipolar A signal range that is always positive—for example, 0 to 10 V.

update The output equivalent of a scan. One update is one write to each

channel or port in the group. Updates apply to both analog

output and digital output groups.

update rate The number of output updates per second.

update width The number of channels in the channel list or number of ports in

the port list you use to configure an analog or digital output

group.
