onnecting with Applications

The LX Series provides a diverse set of connections to popular data analysis applications, which enables
efficiency in all steps of the process: from experiment setup to data recording and processing.

Connecting to Sensors

Using the constant current excitation type accelerometer input amp card, you can directly connect to ICP

®

accelerometers and ICP

®

microphones. You can also read values such as sensitivity and calibration values

for connected transducers. For experiment setup, these features reduce the need for additional equipment
and can automate coefficient settings, thereby eliminating setup errors, and greatly reducing the effort
required for experiment setup and data processing.

Connecting to Existing Analysis Systems

Some existing data recorders have the ability to
perform analog playback and change the playback
speed (matching the analysis system bandwidth
and playing back fast phenomena at a slower
speed, or playing back slow phenomena at a faster
speed, within the same sampling rate series)
The LX Series can replace a traditional data recor-
der even in an analysis system that requires exist-
ing analog data to be played back. At a PC with
the optional LX View program, you can extract
only a necessary portion from an originally recor-
ded file to create a new data file. Then you can
copy the new data file to another media to per-
form analog playback in the LX main unit. This
enables data to be investigated more efficiently.

Connecting to Data Processing Software

The format for recorded data is TAFFmat, the file
format now used by TEAC digital Data Recorders.
Data files in the TAFFmat format can be read by
the LX View and by other companies' analytical
software that supports TAFFmat. Also, in a config-
uration in which a PC is connected and a LX Ser-
ies recorder is used as the front-end, the TAFFmat
format files can be used with software providing
real-time recording and analysis functions. We
also pro-vide the file converter software from
TAFFmat to the popular analyzing data file formats,
such as ASCII, UFF, ATI, and so on. TEAC provides
system integrators with a Windows DLL for direct
control of LX Series recorders. Contact TEAC for
details.

Connecting to Network

Using the 10BASE-T/100BASE-TX Ethernet interface, you can build distributed multi-channel data record-
ing systems. Synchronizing pulses generated by, for example, a GPS signal can synchronize the internal
clocks by using +/-30 seconds' adjustment function of the LX and you can control the recording of
multiple devices connected to the network. The data collected by each LX main unit can be collected
over the network, which reduces the effort required to physically collect media from different locations.

Specifications

S/N (Crosstalk), measured at the Analog Output:

When Using AR-LXDC2 and AR-LXAO
S/N

78 dB (within the bandwidth)

Crosstalk

-

78 dB (below 20 kHz within the bandwidth)

or 75 dB (40 kHz within the bandwidth)
(except for low-sped sampling)

Note: The overall accuracy specified here is the accuracy of the analog output
when using an input amp and a DC output amp, and may differ depending on
the frequency characteristics and the input range of the input amp.

The new LX Series data re-
cording system from TEAC
has been designed for fast
set-up, reliable recording, and
versatile playback in your
data recording applications in
the laboratory and in the field.
Following-on from the conve-
nience of DAT recorders, the
LX Series en-ables recording
in wider bandwidths. The ser-
ies has strengthened connec-
tivity with sensors, PCs and
analysis applications; achieves
fast data processing; and is
designed to lower data re-
cording costs.
