B
backplane an assembly, typically a printed circuit board (PCB), with 96-pin
connectors and signal paths that bus the connector pins. PXI systems have
two connectors, called the J1 and J2 connectors.
backplane
synchronization clock the clock signal that is used to synchronize the RTSI/PXI triggers or
PXI_STAR triggers on an NI 6653
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. An examples of a PC bus is the PCI bus.
C
C Celsius
CLKIN CLKIN is a signal connected to the SMB input pin of the same name.
CLKIN can serve as PXI_CLK10_IN or be used as a phase lock reference
for the OCXO.
CLKOUT CLKOUT is the signal on the SMB output pin of the same name. Either
the OCXO clock or PXI_CLK10 may be routed to CLKOUT.
clock hardware component that controls timing for reading from or writing to
groups
CompactPCI a Eurocard configuration of the PCI bus for industrial applications
D
D/A digital-to-analog
DAC digital-to-analog converter—an electronic device that converts a digital
number into a corresponding analog voltage or current
DAQ data acquisition—(1) collecting and measuring electrical signals from
sensors, transducers, and test probes or fixtures and inputting them to a
computer for processing; (2) collecting and measuring the same kinds of
electrical signals with A/D and/or DIO devices plugged into a computer,
and possibly generating control signals with D/A and/or DIO devices in the
same computer
