HIGH-RELIABILITY DATA RECORDING
Data recorders should have reliable failsafes and
backups as well as multichannel capabilities and
multiple amplifier variations for important tests
// BERND STEPP
The LX-1000 series of instrument data
recorders is designed to provide
multichannel and multiple amplifier
variation recording solutions for the
testing and monitoring requirements of
aerospace, defense and industrialacoustics/
vibration-based applications.
TEAC has been providing data recorders
for the aerospace testing market since the
reel-to-reel tape era and the company
continues to develop and provide
machines that use the latest and most
reliable technologies.
In the past, PC storage capacities were
small and data transfer rates were slow. In
aerospace testing many signals are
recorded at high sampling rates, but earlier
computers did not have a high enough
performance level to record such volumes
of data. Instrument data recorders were
therefore the main data acquisition system
and the files created were analyzed on a
computer after the testing was completed.
Now the ubiquitous PC is the front end of
the acquisition system, analyzing the data
in real time, while the instrumentation
data recorder has become the important
backup system.
The TEAC LX-1000 series has features
that enable it to provide reliable data
recording with protection from
catastrophic data loss, including a wide
dynamic range and high resolution. A unit
can have 64 channels and synchronization
between four units enables 256 channels to
be recorded. The LX-1000 offers a longer

recording time than is possible with tape
recorder technologies.
Moreover, it’s possible to use, add and
change multiple amplifier variations, such
as PA (DC-switchable), AO, strain,
thermocouple amplifier and CAN.
Additionally the LX-1000 has pulse input
and GPS input.
Connection to sensors is eased by
support for the transducer electronic data
