Definition of the Parameter Current and Modulation Depth

3.1.2.3

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.

External Control Mode

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