Click the Shift Waveform Up button in the Toolbox.
In the Scaling menu click on Waveform Up 1 Pixel or Waveform Up 10 Pixels. Waveform Up 1 Pixel moves the specified waveform up 1 pixel in the strip and Waveform Up 10 Pixels moves the specified waveform up 10 pixels in the strip.
OR
Drag in the waveform strip area to draw a selection rectangle around a portion of the waveform. The size of the selection rectangle does not matter, it is merely used to represent the current horizontal position of the waveform on the screen. With the mouse pointer positioned inside the selection rectangle, drag the selection rectangle “up” to move the specified waveform up in the strip to the desired position (within the limits defined by the A/D converter).
Choose Scaling Waveform Up 1 Pixel (ALT, C, P) or Scaling Waveform Up 10 Pixels (ALT, C, U). Scaling Waveform Up 1 Pixel moves the specified waveform up a single pixel in the strip and Scaling Waveform up 10 Pixels moves the specified waveform up 10 pixels in the strip.
+ Select the waveform using the left or right annotation margin. Hold the SHIFT key down. Click and drag the waveform up/down in the waveform window.
