Using the Oscilloscope
Figure 11 Infiniium Oscilloscope Waveform Display Area
The waveform display area shows the waveforms and, optionally, the
results of your measurements. Several display options, including a grid, are
available. You can use the mouse to click and drag waveforms to new
vertical or horizontal positions. You can also click and drag a rectangular
area on the display, then click the Waveform Zoom menu item to zoom on
that section of displayed waveform.
Avoid Overdriving Vertical Input Amplifiers
N O T E
When zooming on a waveform with the oscilloscope running, be careful to keep the signal
within the screen vertically to avoid overdriving the vertical input amplifiers. Overdriving
causes waveform distortion and erroneous measurement results.
Ground reference indicators show channels, waveform memories, and
functions for each waveform that is on. The symbol represents the ground
reference point for each channel; it moves when you change the vertical
offset. You can also drag this symbol up and down to change the vertical
offset for that waveform.
