  • Page 12: Overview

    Overview Overview The LX series instrumentation data recorders can record and reproduce signals of a maximum 48 kHz sampling frequency via 8 channels onto MO (Magneto Optical Disk) or PC card media. Recorded data on the media is stored as PC files. The maximum input channels are 32 channels by using the selectable types of the 8 channels input cards and the optional channel expansion unit.

  • Page 13: Features

    Features Features Input/Output Amps The LX main unit equips 2 slots and the optional expansion unit provides additional 2 slots for installing the input amps and/or the output amps. The input/output amp provides 8 channels inputs/outputs from the below selections. DC input amp card: Use to connect voltages and/or to connect signals of external amplifiers.
  • Page 14 Features A Variety of Recording Triggers Manual: Starts recording manually. Level Trigger: Starts recording by detecting level changes in a specified channel. External Trigger: Starts recording by using an external signal as the trigger. Pre-trigger: A pre-trigger can record the data that was read into a buffer before a recording-startcondition (based on a level trigger or external trigger) was satisfied.

    -> second sampling channel order ->...-> last sampling channel order. At the LX series, ADC value +/- 25000 represents +/- 100 % of the input range. This document uses the term scan to refer to a collection of data resulting from one sampling. A data file is a collection of scan repetitions.

  • Page 16: Notes On Usage

    Use Specified Media Only Use 1.3 GB, 3.5 inch MO disks from Fujitsu Ltd. Use PC cards checked by TEAC in advance (contact us for information). Other media might be unable to record or reproduce correctly. PC Cards Checked by TEAC for Correct Operations (As of August 2005)
  • Page 17 Notes on Usage Clean Disk and Lens Dust might collect on an MO disk or lens after they have been used for a long time. This dust might cause errors. To prevent this problem, clean the MO disk and lens using a cleaning kit (separate purchase). The period after which cleaning is required depends on the environment but, as a general rule, clean once every three months.

    Make sure to specify the source slot installed the input amp at the Output Slot.  At the LX series, the AD value of +/- 25000 is correspondent to +/- 100 % of the input range. So that the output amp outputs the signal at the scale of +/- 100% as the specified output range. For example, if you record + 1V signal at the 1 V input range and you set the output range at 2 V, you will obtain +2 V signal correspondent to the recorded 1 V signal.
