External Control Mode
This mode allows to control the DC3100 by an external signal.
The 'External Control Mode' has no parameter settings. The LED can only be
controlled via the BNC connector at the rear panel of the DC3100. The applied
voltage corresponds to the LED current. 1V is equivalent to a LED current of
100mA. A maximum voltage of 10V can be applied, which results in a current of
1000mA.
Please note: The maximum current is limited by the user defined current limit set in
the 'Adjust Limit' menu.

The Modulation Frequency range is 0 to 100kHz and valid for sine wave modulation.
