  • Page 7: Introducing The Iqs-2100 Light Source

    Source Main Features The IQS-2100 Light Source is designed for scientific and industrial applications using the IQS Platforms. The IQS-2100 Light Source includes a choice of multimode LEDs and temperature-stabilized single-mode Fabry-Perots laser emitters, in single- and dual-wavelength configurations, for both singlemode and multimode test applications.

  • Page 8: Available Models

    For easy repeat access, the software stores multiple power level and modulation configurations. Its Windows-based software allows the IQS-2100 Light Source to integrate easily into any test system. The IQS-2100 Light Source supports local control (via the IQS Manager software) and remote control (through GPIB, RS-232, or Ethernet TCP/IP using SCPI commands or the provided LabVIEW drivers).

  • Page 9: Conventions

    Introducing the IQS-2100 Light Source Conventions Conventions Before using the product described in this manual, you should understand the following conventions: ARNING Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury. Do not proceed unless you understand and meet the required conditions.

  • Page 11: Safety Information

    Safety Information ARNING Do not install or terminate fibers while a light source is active. Never look directly into a live fiber and ensure that your eyes are protected at all times. ARNING Use of controls, adjustments and procedures for operation and maintenance other than those specified herein may result in hazardous radiation exposure.
