The MO2020se is designed to provide a sine wave, or square wave outputs, for testing audio devices. The units frequency output varies from 20Hz to 24kHz. VCO Input: 1/4" jack for connection to a Voltage Control source which may vary from 1.2 volts to 5 volts dc. This voltage allows for external control of the MO2020se's frequency. THE FREQUENCY CONTROL MUST BESET TO MAXIMUM FOR PROPER OPERATION OF THE VCO CONTROL. SQR Out: 1/4" unbalanced jack containing the square wave signal.
