DAT Data Recorders

Connecting 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 recor­der even in an analysis system that requires exist­ing 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 recor­ded file to create a new data file. Then you can
copy the new data file to another media to per­form 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 config­uration in which a PC is connected and a LX Ser­ies 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 record­ing 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.

Many popular data analysis software packages
support the data file format recorded by the
LX series. In addition, TEAC LXView software
is available for fast data file review and file
format conversion.

Easy Setup and Secure Data Recording

Application Software

LX-10 Series - the LX-10 Series provides basic recording and playback performance

with selections of recor ding media and input/output configurations.

Three Types of Recording Media

Memory (from the standard 64 MB to a maxi­mum of 576 MB) achieves maximum record­ing rate; a PC card (Flash memory and IBM
Microdrive

™

) enables data recording in en­vironments where vibration occurs; or a 3.5
inch 1.3 GB MO disk is convenient for long­term media storage.

Recording Via a Maximum of 32
Channels

By combining channel selection and input
amplifier cards, you can record via 2, 4, 8, or
16 channels, or use an expansion unit to re­cord up to 32 data channels.

Simultaneous Recording to Media
and PC with a Selection of Interfaces

Either an IEEE1394 interface or a 100BASE­TX interface can be selected to connect to
the PC. While recording to a storage media,
you can transfer data to a PC in real-time
and display the data on the PC monitor, pro­cess the data, or record the data to hard
disk on the PC. While using the PC for fast
real-time recording and processing of data,
you can back up the data onto a storage
media. This achieves accurate data record­ing simultaneously with fast data analysis.

(Some information, such as events stored in a header file
while recording to media, are not written to the header file
while recording directly to PC.)

Higher Recording Bandwidth

The LX Series can record 8 channels at 20
kHz bandwidth with 48 kHz sampling fre­quency per channel, which is double the re­cording performance of DAT recorders. Us­ing internal memory or transferring data to a
PC in real-time, you can record 8 channels
at 40 kHz bandwidth with 96 kHz sampling
via the IEEE1394 interface, or 8 channels at
20 kHz bandwidth with 48 kHz sampling via
the 100BASE-TX interface.

(Using an IEEE1394 interface in the PC, as specified
by TEAC. The data transfer rate to the PC varies de­pending on the connected PC environment.)

I/O Amp Cards in 8 Channel Units

Two types of input amplifier cards are avail­able; including a DC input amp card and a
selectable DC / constant current excitation
type accelerometer input amp card. The
available output amplifier card can output
the analog voltage during recording and can
play back the analog voltage after recording
for both types of input amp cards.

(The output amp card does not support low sampling
below 1 kHz, and can only reproduce the analog voltage
within the same sampling time base series.

Lower Sampling Rate to Extend
Recording Times

Using the DC input amp card that supports
low sampling rates, you can select a sam­pling frequency from 1 kHz to a maximum
length of 1/60 Hz.

Controlling the Main Unit from a
Remote Controller Unit or a PC

The LX main unit provides LED indicators and
operation keys that are required for record­ing. After you set the parameters, recording
can proceed independently. Using a remote
controll unit or a PC, you can perform a se­quence of operations: system setup, record­ing, monitoring, and data playback. During
recording, the remote controll unit can display
a bar meter and the PC can display a bar
meter, waveform display, or digital display by
us-ing the standard LX Navi software. These
display functions provide real-time data moni­toring.

Trigger Recording

To let you record data efficiently, various
types of start and stop trigger modes are
provided. You can control the starting or
stopping of recording by using external con­trol, level start/stop triggers, timer recording,
interval recording, time-out start, start pre­trigger, stop post-trigger recording, or repeat
recordings.

(Some restrictions might apply to the triggers that can be
used when using a combination of triggers.)

Voice Memo Recording and Audio
Playback

You can record convenient voice memos to
describe recorded data, which simplifies later
extraction. These voice memos are recorded
as WAV files separate from the recorded
data files. Data recorded from any one
channel or the voice memo can be played
over the built-in speaker.

Battery Enclosure

The battery enclosure BU-80 can be at-ta­ched to the bottom of the main unit. In ad-di­tion to battery-powered operation, battery­backup operation is possible using an exter­nal DC power source. Up to 3 battery packs
in tandem for longer life can be stored in the
BU-80, which enables 3 hours of recording
when recording 8 channels to media via the
constant current excitation type acceleromet­er input amp card.

(The BU-80 does not include the battery pack.)

LX-20 Series - In addition to all recording and playback features of the

LX-10 Series, the LX-20 Series provides the selection of additional
sampling rate series, Tachometer pulse inputs, and a signal generator
feature.

Maximum Recording Rate

Record to the internal memory, or to the hard disk
drive of the PC via IEEE1394 interface:1.536 MB/s
(Example, 40 kHz bandwidth with 96 kHz sampling
rate x 8 channels)
Record to the MO/PC card, or to the hard disk
drive of the PC via 100BASE-TX (Pier-to-Pier
connection): 0.768 MB/s (Example, 20 kHz
bandwidth with 48 kHz sampling rate x 8 channels)

Note: Recording rate to the hard disk drive of the PC may
vary depending on the connection and the PC
specifications.

Versatile Sampling Rate Selec­tions for Frequency Analysis

In the LX-20 series, 102.4 kHz, 65.536
kHz, and 100 kHz sampling rate series
can be selected in addition to the 96
kHz sampling rate series, fitting for FFT
analysis data recording by using the
LX-20 as a PC front-end.

Direct Rotational Signal Inputs

The LX-20 provides dedicated 1 × / 2 ×
tachometer pulse input(s) without im­pacting the analog input channel
count.

(Using the tachometer pulse input channels low­ers the maximum sampling rate at some of the
channel settings.)

Output to Vibration Simulators
and Loudspeakers

A waveform generating function is
provided at the LX-20 monitor output
terminal. You can record data while
outputting sine waves, white noise or
pink noise to vibration simulators or
loudspeakers.
