5. External Voltage control output frequency
a) Press down the square wave button [6], select a proper range [5] and set the desired frequency [8].
b) Attach an external control voltage (0 to +10V regardless of polarity) to the VCF input jack [14]; the
signal is available from terminal OUTPUT [15]. The user can now control the output frequency by
adjusting the external DC voltage.
6. External Frequency Counter
a) Set the EXT/INT selector [19] on the rear panel to EXT mode and connect the external signal to the Ext
counter input jack [21].
b) When the input signal is too strong, use the attenuation button [20] to attenuate the signal by 20dB.
