Hi i recently bought a Fnirsi 1014D oscilloscope which has an inbuilt function generator. But the amplitude of the signal is fixed at Peak to peak 2.5V. I tried connecting a volume pot on the out to reduce the amplitude but the signals came out distorted, Is there any way to make it variable by adding an external circuit?
