    This chapter provides basic operating information for the WVR610A & WVR611A Waveform Rasterizers. Overview The WVR610A & WVR611A use a flexible, tiled display. The waveform rasterizer can display four tiles at one time. Each tile can display a different measurement, effectively creating four independent instruments. See Figure 2- -1.

  • Page 56: Figure 2- 2: A Tile In Full-Screen Mode

    The only measurement that cannot be displayed in more than one tile is the Audio measurement. It can be displayed in only one tile at a time. Figure 2- 3: A display with multiple Status screens 2- 2 WVR610A & WVR611A Waveform Rasterizers Service Manual...
