User manual TEAC LX BROCHURE

[. . . ] 45 W for an 8-channel I/O configuration (AR-LXPA1 and AR-LXAO) with media recording DC power supply cable and AC adapter are supplied. Weight Approx. 4. 1 kg Approx. 9 lb (for an 8-channel I/O configuration using an MO disk/a PC card) * Other specifications follow the LX-10 specifications. 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.

Input Voltage 100 V Filter Joint use of both a digital filter (Decimation LPF) and an analog filter (2nd Order Butterworth) LX Router Internet/WAN NETWORK 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.
