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.
