Rolls MO2020se Testoscillator Signal Generator

The Rolls MO2020se is an outstanding signal generator designed for electronic testing within the audio frequency range. It offers versatile output options including balanced XLR, RCA, and 1/4” unbalanced sine wave outputs, along with a 1/4” unbalanced square wave output. There's also a 1/4” VCO input that accepts 1.2 to 5 volts dc for external control or frequency - range sweeping. Key features include a frequency range from 20Hz to 24kHz, multiple balanced and unbalanced outputs, sine and square wave outputs, and a - 30 dB pad for referencing. Technical specs show an 11 dB sine and 14 dB square output level, 100 output impedance, 12 - 15 Volts DC power requirement, and a THD (Sine) of less than 3%.

Using the Rolls MO2020se is straightforward. First, make sure to connect it to a 12 - 15 Volts DC power source. You can then choose the appropriate output connection based on your needs - whether it's the XLR, RCA, or 1/4” outputs. For external control or sweeping the frequency range, connect a device that can send 1.2 to 5 volts dc to the 1/4” VCO input. When using the - 30 dB pad, it can help you with referencing during testing. As for maintenance, keep it in a clean and dry place. Avoid exposing it to extreme temperatures or moisture. If you notice any issues, check the power connection and output cables first. And always follow the safety guidelines when handling electrical equipment.
