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.
