Glossary LMG450
278
Catchword Meaning
D. U. T. ‘Device under test’: equipment which should be measured.
Data output format Format which is used to transfer data from the meter to a PC
or data logger.
DC value ‘Direct current’; signal without alternating components. This
signal is constant over the time.
Default parameters Parameters defined by the manufacturer; the instrument is
set to this parameters when it leaves the factory.
Defined length arbitrary block
response data
Data transfer in blocks with a defined length and random
contents inside the blocks; there can be for example the
⇒
EOS character which will be interpreted as data instead of
EOS. The fastest way to get data.
Demodulation
Inverse function to
⇒
modulation; remove the carrier and
you get the signal you want.
Desired integration time Time in which the power is integrated, set by the user.
Device Every meter or equipment take place in the measurement
(Printer, PC ...).
Device under test
⇒
D. U. T.
DFT algorithm Discrete Fourier transformation; operation with discrete
values using the Fourier integral to get the harmonics of a
signal.
Digital filter Filter built up with digital components and software.
Digital Input
Like
⇒
Analogue inputs the LMG series provides digital
inputs, to read external states.
Digital Output
Like
⇒
Analogue outputs the LMG series provides digital
outputs, which can be used to signalise states (e.g. alarm
outputs).
DIP switches Small hardware switches to set up a meter parameter, like
communication speed.
Direction input Input for motor testing to measure the rotary direction of the
motor.
Dot joiner Connects the dots of the measured graph; it improves the
look of a graph.
E
E. U. T.
⇒
D. U. T.
Echo Repetition of characters sent via the RS232 to the
instrument.
Edit line Line in which you can change a value or text.
Efficiency measurement Efficiency is the relation between the output power and the
