    2 Getting Started Operating the DC2100 The DC2100 can either be controlled via the front panel of the main unit (see chapter Operation and Settings) or by a remote application (see chapter Remote Application). Operation and Settings The following sub chapters contain the description about the operation of the DC2100.

  • Page 13: Operation Modes

    This can be done while the main menu is selected by pressing the LED button. The last selected operation mode will be saved. After switching on the DC2100 again this operation mode will be automatically the active mode. All settings are saved and validated after a shut off.

  • Page 14: Pulse Width Modulation Mode

    3 Operating the DC2100 3.1.2.2 Pulse Width Modulation Mode This mode can be used to apply a pulse width modulation to the LED with a defined frequency, amplitude, duty cycle and number of periods. Especially for spectral and power measurements this operation mode can be very useful.

  • Page 15: External Control Mode

    The 'External Control Mode' has no parameter settings. The LED can only be controlled via the BNC connector at the rear panel of the DC2100. The applied voltage corresponds to the LED current. 1V is equivalent to a LED current of 200mA.

  • Page 16: Settings And Configuration

    3 Operating the DC2100 Figure 13 External Control Mode The Modulation Frequency range is 0 to 100kHz and valid for sine wave modulation. 3.1.3 Settings and Configuration There are settings and system configurations, which can be accessed via the main menu.

  • Page 17: Settings

    LED Configuration The LEDs maximum current can be reconfigured for LEDs with an EEPROM. This value is valid until the DC2100 is restarted and can be changed in the 'User Limit Current' menu. This menu entry is hidden in normal operation mode. Go to the 'User Limit' screen described above.
