L
LabVIEW laboratory virtual instrument engineering workbench
latch a digital device that stores digital data based on a control signal
latched digital I/O a type of digital acquisition/generation where a device or module
accepts or transfers data after a digital pulse has been received. Also
called handshaked digital I/O.
LED light-emitting diode
level DAC the calibration DAC used to change the voltage levels to another device
low-pass filter a circuit used to smooth the waveform output and removed unwanted
high frequency contents form the signal
LSB least significant bit
M
mmeters
M (1) Mega, the standard metric prefix for 1 million or 106, when used
with units of measure such as volts and hertz; (2) mega, the prefix for
1,048,576, or 220, when used with B to quantify data or computer
memory
marker a digital signal that is generated on a pin on the digital I/O connector at
a requested point in the waveform buffer; this happens while the analog
waveform is being generated at the DAQArb 5411 Arb output connector
MARKER marker output signal
marker offset the position, in number of samples, from the start of the waveform
buffer at which the marker is requested
master/slave locking the DAQArb 5411 clock in frequency and phase to an externa l
phase locking reference clock source
