    oscillator to the vertical input of the oscillator. Adjust the sweep and triggering controls until a stable pattern is observed. Positive slope means that triggering can take place only on an increasing voltage‚ even if the value or level is negative. Selection of the appropriate slope and level can help to trigger the sweep at any point like on the input signal. Use the oscilloscope to measure the peak to peak amplitude of the voltage from the audio oscillator. The amplitude of the voltage is half the
