  4.  Display  will  show  the  frequency  and  Hz  /  kHz  LED’s  will  light  depending  on  the 
frequency. 
5.4  VOLTAGE CONTROLLED FREQUENCY OPERATION (model 4003A only) 
  The 4003A can be operated as a voltage controlled generator by using an external control voltage 
applied to the VCF input. 
  1.  Select the desired frequency range and waveform. 
  2.  Set the starting frequency with the variable control.  Apply a  positive DC voltage to the 
VCF input to increase the frequency. A voltage from 0 to +10 V will cause the frequency to 
increase by a factor of 100.
